Dolphin Pool Cleaner - BROKEN is FIXED!!! SOLVED with 1$ Bearing | HOW TO REPAIR for MOST Models!

[@AngeloDellaPorta-k7y]

Hi Luke, thanks a lot. This was exactly my problem. I've spent only 1 dollar, 40 minutes and could fix it. you are the BEST. best regards from Switzerland Angelo

Hi Luke, I have a dolphin, E-10, it seems lately the unit will go on the bottom as it goes through the debris. The debris just blows around. It does not seem like it has any suction yet I do see water coming out of the top. Any ideas why this would not have any suction? I checked the impeller, and there was no debris. Mike

[@LeisureLuke]

@@michaelbennett3202 If water is blowing out the top, then you have suction coming in the bottom. If it's able to cling to and climb walls, your suction is good enough. I'd double check your filter basket for small tears, any small tear means that filter basket will pretty much not work at all. Also make sure it's assembled correctly and sitting right in the unit. If you're climbing walls, and your filter basket is clean, then it should be sucking up and cleaning something! Hope that helps.

Awesome video. Thank you for helping the algorithm find this repair and saving big $$$ A few notes as I'm mid-repair: 1) The sealed unit itself can be really hard to open. I used the shaft of a screwdriver (not the pointy end) to pry it apart using the clip brackets as leverage. I slipped a credit card into the gap to help work around. When it finally opened there was a large pop - I think the unit was REALLY well sealed and the temperature swing at night when I tried to open it caused a pressure / vacuum making it extra hard. 2) The long screws on the motor itself have SUPER SOFT heads. Immediately stripped one of them using a regular screwdriver. And that's the point I'm finding myself stuck at right now. Ugh. Be careful everyone with these! Might end up having to buy a new motor just because I've stripped some darn screws 😵 There is an eBay seller out there who will repair/refurb your motor for ~$110, or sell a kit of all the necessary parts for ~$30. Might be worth it if there's a lot of parts that need fixing, or if you're happy to outsource part of the fix without shelling out the full $450!!

[@bristolj.buckets8968]

Thanks for the tip of using the shaft to pry open the black motor box. I was stuck.

[@JP-hj2gs]

@@bristolj.buckets8968 I was curious about how well it was sealed. Thanks for this!

[@tutube112]

Could you please give us instructions on how to open this black open. I don't want to force open and at the end I can't close it tightly.

[@theringostarman]

I spent $180 to replace the blue cable on my DOLPHIN Nautilus CC. It would only run for about 30 seconds and just stop. No indication on what was happening. Local pool shop suggested to replace the blue cable and I let them. Got it home a week later and of course it didn't fix my issue. They then suggested to replace the motor.. Adding up the cost of the potential repair, and I could have gotten a new unit for the cost of the motor and cable! :) I will for sure be taking my motor apart this afternoon to see if the bearing is the issue! Thanks for making this video!

[@LeisureLuke]

Good luck! While you are in there you can check both motors. Some people have actually done the same fix on the other motor too! I’d use your old cable and save the new one :) someday you’ll probably need it! Might as well squeeze out the life of the old one!

[@theringostarman]

@@LeisureLuke so taking the motor out in of itself showed me the issue. The propeller had hair and twine underneath it in a way I wasn’t able to see it from the top down view. Took the prop off the spindle and removed it and it’s working perfectly!!

[@johniannetta1822]

My Maytronics Dolphin Active 20 just started having this problem where the impeller is not spinning. I bought brand new in 2020. We use it everyday in the summer. This is the 3rd season. With your instructions, I was able to take it a part. There was all this black carbon flakes. I used electrical contact cleaner to clean the inside of the 24V impeller motor, and both bearings. I couldn't take out the 3rd bearing off, put it all together and everything is working - back to normal! Without changing any parts! This took me 2 hours to do at a easy comfortable pace. Thank you for making this video. You saved me $1500. I was almost going to buy a new one.

[@LeisureLuke]

Nice!!!! Congrats on the fix! It’s not a job for the faint of heart, and sounds like you did a thorough job and cleaned it like new! The black dust is normal - it’s from the wearing of the motor brushes, which I’m guessing will be our next failure and next fix-it video :). Well done! Party accordingly!!!

[@chuckanthony6451]

DUDEEEE credit where credit is due!!!! Dolphin moved backwards a few inches then forward a few inches then nothing. Checked impeller and stuck solid. Followed ur video and believe it or not a local skate shop had my bearing in stock and I fixed it in less than an hour. Saved me my hard earned cash man! Thank you!

[@LeisureLuke]

Nicely Done!!!! Happy to have helped!

[@mattanderson3389]

Got the bearing replaced and motor put back together. The seal must not have lined up right, Dolphin worked for about half hour then stopped. I took it apart and the housing for the motor is filled with water. Looks like I'll have to purchase a new one. Thanks for video, was super helpful!

[@LeisureLuke]

AH! Shoot! That's a tough one to stomach, but you did all you could to save it in the first place. Enjoy the new pool cleaner, and let me know which you end up getting!

[@jillmhunter]

I'm 2 minutes away from ordering a whole new Dolphin but your video was so well done that, even though I've tried everything else, short of opening the motor, - which makes me nervous - you've given me the confidence to try this. Sounds like it is just the bearing and that will save hundreds!

[@LeisureLuke]

I hope that's the case and you're back on your way to a clean pool!!! Yeah, it's worth trying anything if the alternative is a new $1k unit! :D Good Luck!

[@squidlips5368]

Hey mate, thanks for the great video, saved me $600 AUD for a new motor. Ended up being the brushes not the bearings, cost me a grand total of $10 to change them out. Although not the same problem as yours, your video gave me an insight on how to pull it apart & put back together again, working a treat now. Cheers from OZ

[@desertsynthguy]

Literally, you saved me $450 AND the fix was free !! Took apart as you did, took the motor apart and the inside was caked in fine carbon powder. A bit of compressed air later, the motor cleaned, everything back together and good as new. Thank you.

[@LeisureLuke]

Awesome! Nice work :D Party Accordingly :D

[@billc6087]

I'm having this same problem, so I'm very glad I found your video! I'm adding one brief note - when reassembling the motor housing I checked the gasket for any impurities and then added a small layer of silicone grease. I bought this tube of pool-grade silicone grease for my pool filter when I replaced the cartridges and o-ring a couple of years ago and it's proven useful on many other occasions.

[@uncleruss01]

Thank you Luke. I had the same problem on my Dolphin Deluxe 4. It has 2 bearings 626rs and 608rs. Truthfully, I only really needed to replace the 608rs, but since I was already in there and its like 10 years old, I replaced both. Additionally my circuit board had some corrosion and a burnt up resistor. I got some 90% rubbing alcohol and cleaned the circuit board. Determined the burnt resistor was an 18 ohm 1/2 watt, soldered a new one of those in and let'r rip. It runs like new. I would not have done any of this without your video. So here's the breakdown. Multi pack of resistors $13. 10 pack of 626rs $9. 10 pack of 608rs $8. Rubbing alcohol from Wal-Mart $1.50 and a tube of silicone lube from HD $5. So, less $40 for enough parts to maybe keep this thing going for another 10 years. A ton of simple knowledge that I got to learn with my 15 year old son. It's a joy to watch a once dead Dolphin that I paid a $1000 for still going. One more tip. I've always had the habit of keeping those little silica packets that come with all the Chinese junk we buy. So I stuffed like 8 of those in the box to hopefully stop or limit future corrosion. I realize this this is now old and not as water tight as it used to be, I will probably open this thing up a couple times a year just to make sure. Thanks again Luke, you're AWESOME!!!!

[@LeisureLuke]

Well done Russ!!! You really went the extra mile there, sounds like thorough and excellent work! You should be proud to have revived something, saved money, and probably learned a lot! Happy to be the inspiration to crack everything open. That’s some seriously good work 👍🏼👍🏼👍🏼

[@chief44vp]

Hi would these bearings be the same on dophins200 Vince

[@DieselMike]

Hopefully you are still checking comments... So my S300 will go forward as it should. Climbs the wall no problem and creeps along the tile line while bumping up against the coping. But then when it decides to go in reverse, it will do so for only a few seconds and then stops moving. Gravity will make it sink to the bottom of the base of the wall and after about 30 seconds it will resume going forward again. As a result, it's constantly climbing walls, but never finding the floors where all the filth is. Also take note that when it is just sitting for those 30 seconds immobile, it is still blowing a lot of water out the discharge vent as I can see all the turbulence in the water. So this makes me assume my impeller is working. Regardless, your video is very helpful in informing how to take the guts apart and possibly looks for clues. I am going to try it tonight. So thank you for that. But in the meantime, any suggestions as to what is causing what I am describing?

[@LeisureLuke]

Hey Mike, any luck? Not sure what it could be. If your drive motor or drive belts are getting stuck only in reverse, that’s pretty unusual. Maybe someone else here will have a better idea.

[@DieselMike]

@@LeisureLuke Unfortunately no. I dug into it and impeller was clean as could be and spinning freely. Then I opened up the sealed box to look for any visible issues, like water inside or burnt out circuit boards. Again, all good there. I removed the belts from the wheels, all the teeth were good and catching the sprockets. So I buttoned everything back up, dropped it in the water and same thing. But then I did another test that may provide a clue (sorry this is so long): I held the robot by the handle suspended under water (so there would be no friction on the wheels) and turned it on. The drive went in forward, then after a while stopped (as it is supposed to) and started going in reverse (as it should during it's cycle). It STAYED going in reverse for some time! When it cycled again (forward and then reverse), I then let go of the robot to allow it to sink to the floor. As soon as it made contact with the floor, the reverse stopped (while still blasting plenty of discharge out the impeller port). Eventually, it started going forward again on the floor and back up the wall. So it appears that if there is any friction on the wheels (belts), the motor doesn't have enough power to move it. But ONLY in reverse?!!! This makes no sense to me. So I am wondering if I can replace or repair the drive motor in a similar fashion that you repaired the impeller motor? I would hate to spend over $400 to replace the whole guts when possibly one small component may be bad. Any further thoughts? I submitted an online request to Maytronics explaining all this. Have not gotten a response yet.

Nice fix! Its always nice to be able to fix things rather than having to throw them out.

Hey Luke, big shout out form Canada. After procrastinating for the summer I finally found your vid and did the same. The bearing cost me $7 here but still cheaper and quicker than sending it in to a shop. Thanks for the great vid.

[@SDsurferguy1]

Fixed!!! Thank you!!!Dolphin Nautilius CC Plus. 4 years old and I always leave in the pool. Robot would run for about 1-2 minutes and then stop and the blower fan on the top would continue to run without moving the robot. Fixed: opened up the motor assembly and found the motor that drives the wheels to be completely full of electric motor dust. Picked up a can of contact cleaner for electronics ( and safe for plastics) and cleaned the hell out of the motor. The bearings after cleaning rolled smoothly so I didn't need to replace. Put everything back together - be mindful of the little odd looking washer that sits ontop of the bearing- kind hard to put back but you'll figure it out with time. Only thing I noticed while it was opening the the brushes on the motor were running a little low. If it acts up again I'll plan to buy some extra brushes to keep the motor running. To make sure you have good seals you need some pure silicone grease. Total cost to fix: 1 can of contact cleaner: $12 since I already had the silicone grease.

[@patescalona3035]

My Nautilus CC Plus was spinning the impeller for a few seconds but the motor for the tracks wouldn’t start. Followed your advice and checked the bearings. Replaced one of the impeller motor bearings since it was noisy and failing. Back in business! Thanks for this video!

[@LeisureLuke]

Nice work!!! And good to know the same issue can appear on the drive motor!!!

[@juancabello6576]

Great video. The same problem happened to my pool cleaner, your video inspired me what to do and it turned out that the bearing next to the brushes was blocking. I lubricated it with oil and the problem was solved, but I bought new bearings and will change them later. Thank you, thank you, thank you. Greetings from Spain.

[@LeisureLuke]

My favorite result! Glad to hear you were able to find the issue! I'd still replace that bearing, but it sounds like you've bought yourself some time. EXCELLENT JOB!!! Party Accordingly 🥳

[@ryanmcdaniel7030]

Thank you for the description and link to the bearings- that saved me a lot of research! I pulled my Dolphin apart last summer when it refused to run for more than a minute or two and found that same bearing you changed was not turning smoothly in my motor. I lubed it with some oil put it back together and the robot worked for the rest of the year. Fast forward to this Spring and that bearing was rough again so it is time to replace it. Oil has it working for now, but the bearing really needs replacing. One note for your viewers- when I reassembled the motor the first time it was running backwards and I needed to swap the red and black wires / brushes to the opposite positions from where they were originally to get the motor to spin in the proper direction. I'm not sure how I managed to get something backwards as it seems like all the parts were keyed for one orientation. I think it might have been the brass cap at the end of the motor. It isn't keyed to the motor housing but is keyed to the plastic enclosure. I think that going on opposite to original resulted in the terminals lining up opposite to where they were previously. I recommend putting an alignment mark on the brass cap and motor housing. It will help with aligning the screws to the holes, too. Does anyone have a source for replacement brushes or the brush springs? I don't know how long these will last, but it would be great to be able to replace them when they wear out.

[@LeisureLuke]

GREAT feedback Ryan. Nice work on oiling up the bearings! Bummer that's only temporary, but at least it reassures you that you've identified the problem! I've seen a few people ask about the brushes and brush springs. From what I can tell these aren't parts that wear out in the life of a dolphin, yes, these wear out in electric motors (usually before the bearings), but you would probably have to run a 2+ hours a day for 10+ years to actually wear those out. That being said, they're generic, and brushes are sold by size, so if you remove the brush, measure the width & height with a caliper, you should be able to find that brush size on ebay, and you'll have to guess at the length. Springs too. I search a bit and found springs that looked the same. I didn't buy them to verify. Again, good work, and good luck when the replacement time comes!

[@ryanmcdaniel7030]

@@LeisureLuke Since my first post, I replaced the bearing and everything is running smoothly again. I used the terminal puller you recommended to pull the bearing. I used a small bolt between the puller head and the axle to reduce the diameter down to the appropriate size to not interfere with the bearing race as it was being pulled off. It worked great! This is pretty embarrassing, but somehow I managed to get my terminals backwards AGAIN even with being aware of the issue and had to take it apart another time to fix that.

I'm decided to try and replace both bearings of the impeller motor anyways, and the error cleared and is working again. Thank you for your video!

[@scottsegura5903]

Thank you. My Pentair Prowler 920 (Dolphin Active 20) stopped working. It would move a couple feet and shut off. I pulled it apart and noticed a ton of black soot everywhere inside the motor unit housing. Upon further inspection it was dust from the impeller motor brushes. I pulled apart the impeller motor and it looked terrible, I wiped it down really good to remove the dust and it cleaned up nicely. The bearing was okay. I re-assembled and now it is working. It's a bummer you can't find the impeller motor (5500024 in my case) anywhere as I'm concerned the brushes are worn and may eventually need replacing. Thanks again as I was able to repair this for $0 and a couple hours of time.

[@LeisureLuke]

We’ll done! Yeah, those solid brushes create lots of dust… they are generic brushes that can be replaced just by measuring the height & width and ordering the right size brush on eBay. Sounds like a few other commenters here are considering the same thing when the time comes. Nice work on your repair !!!

[@mtbdad]

Great how-to video! Thanks for saving me significant replacement $$. I almost ordered a new robot right away, but figured I'd try this first. It fixed my Dolphin model with the exact same bearing, threw it in the pool and it started working again. I used toothpicks to move the motor brush springs off and then used them to hold the brushes back while inserting the electric motor back into its housing. With the extra bearings, I'm ready for 4 more repairs if necessary.

[@mkanyuh]

This is a great video...my bearings where fine ...my motor was packed with carbon dust...cleaned it out and it runs fine now....this video is great showing all the steps...the engineering on this machine is fantastic...taking it apart and reassembling it is pretty easy...all the parts are indexed to only go together properly...even the power cord. thanks so much....saved a LOT of money. I recommend cleaning all the gaskets as you reassemble...just to keep water from creeping in. I sure wish they would sell the individual motors inside the $450 assembly....why engineer it so well to for repair and then not sell the interior motors?

[@LeisureLuke]

Thanks for the comment! That carbon dust is a build up from the brushes wearing away on the motors. These are "brush motors" vs "brushless motors". Some people eventually have to replace the motor brushes when they become too short over time. Glad you fixed it! I agree about cleaning the gaskets, but I'm worried about getting the wrong silicon grease to coat them in before reassembly. Do you know what the right stuff is? Nice fix - one less thing in the dump and $1k saved a little longer! Great Job, party accordingly :)

Thanks Luke, I had the same problem and your video gave me the confidence to try the repair. Replacing the bearing was a piece of cake. Reassembly of the motor was a little cumbersome because of the brushes. Next time I think I will retract the brush springs and let the motor housing keep them off the brushes. Getting the housing for the motors and circuit boards back together with the o-ring properly in place was a bear. After 30-45 minutes of swearing I decided to try my woodworking bar clamps (2) to draw the housings together while using a piece of wood to tuck the o-ring between the two housings. In two minutes the housing was back together and after 3 days the cleaner still works. I’m fairly confident I just saved a thousand bucks. Thanks.

Thank you, Luke, for the video. My Dolphin Triton PS stopped working after two years, right after the warranty expired. The lady at the pool store said that the model was an "internet special" that broke early (I purchased it online). I was not happy, I'm used to such large purchases lasting many, many more years. Anyway, I went through your tutorial--first, I could move the fan but it did have some resistance, so I moved forward. When I got the motor out, a bunch of rust-colored water spilled out: the gasket had failed. The circuit board had some pieces that fell off after soaking in water. I didn't go past that so now am going to purchase a new robot. I thought about replacing the motor unit, but I also would need a cord, since that would all cost $600 plus I'm leaning towards a new one around $850. However, the reviews tout the Dolphin Nautilus CC, but I'm so hesitant to get a Dolphin. Perhaps I will, and after 2 years, pull everything out and replace gasket and parts. I'm not sure :(

[@LeisureLuke]

Sorry to hear that rob. I would get a new one vs fixing yours. Once you have water damage you're looking at replacing everything internal and it's work without a warranty. You'll be happier finding the store with the best, longest warranty possible and getting that! Seems like purchasing through a local pool store that clearly states their warranty is the best thing. If it were me, I'd start reading through Amazon adds and get the highest-reviewed product that has a warranty (you will have to pay to ship it in). These things just aren't made to last, but a new one will undoubtedly be better than an old one. Hope that helps.

Thanks to you, I had the confidence to take a shot at fixing my Dolphin M500. My unit would attempt to move, lurge and stop... usually sideways . Suggesting the motor bearing you discuss. I pulled off the top and side covers off. One track seemed to be able to work freely, but the other was binding up. Then I flipped the unit upside down and pulled off the four screws holding the center drive roller. At this point, the ball bearings in the gear drive assembly for the drive roller fell out on the table ! This bearing had failed. The specific part name is “Active Brush Holder Kit”. So it was not the motor bearing, but still a bearing... and an easy fix! I located the part from the parts diagram from a supplier and it’s on order. $9 part to fix my $1000 robot! Thanks for your tips. Got R Done!!

Trying to drive the tracks is really hard to do but the impeller is free as a bird. SO for me its likely to be the movement motor has a seized bearing. Here's hoping that my Polaris p825/Zodiac CX20 motor unit is as serviceable as yours was. cheers

[@LeisureLuke]

Very likely, I've read comments of several other brands/models with the same issue on drive/impeller motors. Fortunately, most come apart easy, and you've got nothing to lose! Good luck & keep us posted!

[@philliphurst3752]

Mine is the nautilus cc plus my impeller seems to be fine but the drive motor shaft is barely moving and noisy. I’m going to give it a try. Thanks, didn’t expect it to be that easily repaired these things are usually impossible to get apart without breaking something is the reason I didn’t give it a try. Now I’ll take back apart tomorrow. Thanks so much! Phillip Hurst

[@LeisureLuke]

I’m impressed with how well these come apart and go together. I know other nautilus cc owners have fixed their drive motors the same way, and I’m 99% sure those call for the same bearings! Good luck & keep us posted!

I'm going to try! Mine is broken in the same way! Thank you so much.

[@stodini]

Thanks for this video! Easy to understand and follow. I got mine down to the impeller, before opening the box, and the impeller was easy to turn but had a lot of hair around the shaft. I cleaned that off and thought I'd gotten off easily, but it still does the 10-15 second run and stop. Should the impeller twirl, or just be able to turn.?

[@LeisureLuke]

Nice, the problem is usually just a stuck impellor clogged with hair, sticks, etc. The impeller turns hard, but can be turned. I would say it does not "spin". You can't flick it and watch it twirl, but if you grab it you can rotate it.

[@richardwrobison]

Looks awesome! My Dolphin stopped working and it may be the same issue. I will check it out and see. I will let you know. Thanks.

[@LeisureLuke]

Good Luck! If the impeller is clear of debris and still doesn't turn easily it's probably this. Worth checking out!

[@zadina59]

Follow up- The motor was seized. Mine had different size bearings inside. I had to replace the 626RS bearing AND one of the motor brushes. It was difficult finding both parts. I had to order the bearing online. I found a motor brush locally but had to file it down to the proper size. I got everything back together easily and it works as it should. Thank you for your helpful video!

I have just had my robot for 2 weeks. It is running but leaf sometimes got into the impeller. I can took most leaf out by squeeze my fingers onto the impeller. I am already tempted to taking it apart after watching your video.

Yeah, it's just a few screws. Keeping the impeller clean is crucial. I clogged impeller won't let your suction properly, so climbing walls and clinging to corners can become problematic. Good Luck! You Got This!

[@glennmartin2192]

Nice and concise, I took mine apart thinking your diagnosis was causing mine to stop.....but all bearings were running freely. then I separated the main body away from all electrics and diagnosed the tracking system.....there seemed to be an irregularity to it. Forensically examined inside the tracks and squashed piece of tree was inhibiting the smooth running.. These pool cleaners have a memory system to them......when once stopped for what ever reason ...they continue to stop which make diagnosis deceptive...................Currently cleaner and dad are now happy chaps......all the best from Australia

Nice work! That debris can be tricky to find! At least now you're prepared to identify a bearing should you ever have that problem. Well done! Cheers!

[@travislangley4209]

Thanks for the great video. My impeller has no debris and will turn, but will stop immediatley if I stop pushing it. Should it continue to spin on its own after I give it a nudge?

[@LeisureLuke]

Nah, there's some normal motor resistance as you pass the magnets. If it's seized it'll be hard or impossible to rotate at all. Sounds like your problem isn't the impellor motor bearings. Good luck!

[@134lifeplay]

Hey Luke, great vid... I'm just waiting on a part in a last ditch effor to fix my Maytronics DB2 also.. My issue is a seized servo motor and it was difficult to find the replacement (if the one I ordered is correct). Have you had any issues after opening the motor with water getting in? I was thinking I might put some silicon or something around the seal as the repair shop said they would not even open them due to water problems after this is done.

[@LeisureLuke]

Haven't had any water issues, but you could add some new Silicone Grease to the rubber gasket rings. Just be careful putting the lid back together to slide it on evenly. It's built to be a serviceable part, you can even take the lid on and off without tools.

[@frankortolano5886]

Excellent video, I just got mine the S200

[@LeisureLuke]

Nice! Hopefully you don’t have this repair anytime soon, but you’ll be ready when the day comes. I’ve got 2 now, and this is the only failure I’ve had. I’ve replaced the filters when they get a cut, and the cables will need replacing soon. Other than that these are great!

[@timmajors7486]

Sounds like you're on the right track, and have found a problem! That's basically steps 1-4 of 5 done! NICE! GOOD LUCK!

[@jamesduffield8335]

this is great advise thank you but I can separate the top part of the case from the rest of the motor unit, how did you do that?

[@LeisureLuke]

Yeah, that's tricky. Those plastic clips all need to be unclipped. Then the lid is just held on by squished rubber seals/gaskets/rings and some grease. You can use a flathead screwdriver to work your way around prying up the lid evenly until you're able to remove it. Just be careful not to cut those rubber seals and you'll be alright. Good luck.

I would only check the ones than can't spin. Since my robot was scooting forwards and backwards, I knew the drive motor was OK.

Great video. My impeller definitely spins fine, but my unit shuts off after a minute or two. Maybe it's the drive motor? Can you comment on how freely the treads should be able to move by hand? Although it performs the out of water test, my treads will move, but it is definitely not easy to move them.

I have the same issue. Out of water test it worked but put back in the water, it goes forward then back and stops within 10 sec. Visually I didn't see any dirt in impeller and it turned around but I don't know how freely it should move. If someone can comment would be perfect. thanks

[@cedricbeaudeparis9542]

This is pretty awesome, Luke! Thank you for taking the time to share your fix that worked on my Triton Maytronics, which also has the 626-RS ball bearing. At least, the one that was defective. The other one is 608 if I recall correctly. Both shields were collapsed, it was pretty impressive. There was also a lot of dirt/metallic dust inside, and fortunately no water. I took pictures that I am happy to share. I just don't know how to post them here. Thank you for allowing to save additional frustration and expenses! Triton is now back in service (although I had to restart it twice times, possibly until the fault cleared by itself. I wasn't able to reset it via the app, which seriously needs improvements. A cool project would be to be able to start the robot from Wifi or set more than 3 repeats (useful when on vacay). And how about a feature that would allow Triton to not be tangled in my tikki table and stools in the pool? That would be nice!

The water flow piece that controls left and right does not move freely, in fact it clicks. No debris present, but at the point where I am going to pull the unit apart and attempt to fix myself. 30i active and issue started with a few months of purchase. I moved and it went to storage and I lost track of the warranty period, which has since expired, hence self repair.

You have to unclip the plastic clips, and then just work your way around with a small pry bar, screwdriver (careful not to gouge it up), or a putty knife. It's on there pretty good, and is just pressed on with 1 or 2 rubber seals. If you work your way around with a tool it'll open.

[@chief44vp]

Hi Saw you video looks very easy to understand how to go about changing the bearings What bearing size and how many do I need for dolphin S200 Vince

[@LeisureLuke]

You'll probably only replace the one that failed, but each motor has 3 bearings if you wanted to replace them all. The s200 probably uses the same 626rs bearing as the 300s. The good news is most bearings have the size printed right on it, so you'll know what you need once you take it apart and find the problem bearing. If you have any questions, let me know! Worst case, you can measure the bearing with a calipers, and use that to lookup what you need. 626rs = 6mm Inner Diameter (ID) x 19mm OD x 6mm thickness and RS = Rubber Sealed. The seal doesn't matter, just the size.

[@tompicking653]

This winter i replaced the cable, rats chewed it into 3 pieces. 3 weeks ago when I opened my pool the Dolphin Nautilus CC Plus would not run, it was running last year. The power supply is putting out 29+ VDC all the way thru the new cable, the cable continuity is good. I opened the motor box. It was dry and like new inside. Both motors rotate with what I feel is the correct amount of resistance. I tested approx 3 ohms on each motor terminal. My new cable is a 2 wire. The old cable was a 2 wire, the output of the power supply is 2 pins. Inside the motor box I notice that the motor leads are red and black. The connector inside the motor box has 3 wires, red, black, and white. The cable connector is clocked to the connector in the motor box, it can only be inserted 1 way. The 2 leads from my cable connect to the white and black wires inside the box. Could this be the problem? Should the input power connect to the red and black instead of black and white? I have read somewhere that some Dolphins are 3 wire if they have remote control. Maybe that is what the white wire is for. I wonder if I could modify the wires inside the box to correct the problem. Maytronics has not been able to help, the only time I was able to finally talk to a service rep he did not know the answer, put me on hold to check with someone else and then we got cut off and he did not call back. Please help.

[@LeisureLuke]

I’d keep trying their customer support. Sometimes you can call your local pool store and they will impart some knowledge for free. I don’t know if red/black or red/white is the correct hookup. I tend to wonder if it’s a control signal or perhaps some EU spec for their 220v systems. I’ve got no knowledge here, hopefully someone else responds :). Good Luck.

Great video! My Dolphin Triton PS was not moving, but still had water moving through it. I disassembled the impeller motor and cleaned out the black powder with electronic cleaner and air compressor. It is now working, but not going up the wall and falling backwards (pop wheelies as other described). I am not sure what you mean that the red and white wires were reversed. Do you mean on the mother board (green plate)? I don't know how to solder, so what is an alternative solution? Did I put the magnetic cover over the impeller upside down? Thanks for your assistance!

[@killer01ws6]

Hey Luke, Fellow Fipper owners. So, this week out of the blue.. my flipper started the dreaded move forward a foot, back a foot and stop.. I took the impeller top off and the bottom basket and its cover area.. nothing noticeable.. I CAN turn my impeller by hand, but it will not just spin it is tighter than that, seeing I never tried to mess with it new, I don't know the resistance level of it. but does this sound like I need to tear the impeller motor down also? I left the cover off of it and watched and it never does engage.

[@LeisureLuke]

Hello! There is usually resistance in the impeller motor, such that you could never spin it like a top, it's motor with magnets, and they tend to want to hold the impeller in place. That being said, I'd still take the impeller motor apart and look inside your black box for any signs of water damage. Sometimes cleaning out the carbon dust helps, you'll be able to check the bearings by hand, and you can check the length of those motor brushes, some people replace them and say it helps. Remember to mark which color wire goes to which side of the motor - it matters :D Good luck!

[@staceyzaff614]

Are there 3 bearings or 2? I have one on either side that spin but I suspect there’s one more that’s wedged in to the main part - I’ve watched the videos a few times to try and figure it out- excited to see where I land!

Sounds like the sort of error one could get with a seized bearing. Along with any other electronic failure 😣 I recommend taking it apart down to the impeller and give it a few turns.

question please: My Dolphin E10 lifts up in the water (almost straight up before laying back down over and over) while vacuuming. What is this? Thanks!!

[@LeisureLuke]

Check your impeller. As the impeller gets clogged with hair and debris, it'll become less efficient. Unplug the device, and with a hand screwdriver you can quickly get down to the bare impeller (the fan blade). It's a little sharp. Clean it and the area underneath it. Hopefully that'll do it!

[@michaelmcdowell30]

Hi Luke, thanks for the video, my impeller spins, was your not spinning at all or just tough to spin?

[@LeisureLuke]

It's always a little tough to spin, that's normal magnetic resistance in the motor. IMPOSSIBLE to spin means you have a bearing problem. I couldn't spin mine at all by hand.

[@malcolmgrey6172]

Water in motor! Great video. I had the exact same symptoms though the impellor was not seized, just a little firm. Unfortunately when I split the motor housing open I found WATER INSIDE. The unit had never been repaired before and no cracks were evident. The motor bearings all seem free enough and spin OK. I will test the motor. Do you have any tips for re-waterproofing the motor housing.

[@LeisureLuke]

The housing should have 2 rubber ring gaskets and lots of marine grease. It’s probably worth understanding where the water leaked from - there’s 2 motors, the cover, and maybe some wiring that all goes through that black box.
