You are amazing! I have used your videos to replace the flow switch and circulation pump on my spa. You are so detailed that someone with very little experience can figure out how to do it and save a lot of money. Thank you for helping.

Yes who ever put that second screw in the back of the bracket dose suck that made me laugh it's nice to see a real human being suffering along side with us thank you for making this video

Great instructions. Just what I needed to fix my problem. Thanks

@@spaman5440 I’ve got an FL1 error on my J235. The number 1 jets aren’t working and it isn’t heating but the number 2 jets all run ok. Does that suggest it’s the flow valve? Or is there some second pump somewhere for the number 2 jets? Great vid thanks 👍

How do you test your recirculation pump to know if it needs to be replaced?

You would need to call the office and talk to Scott and Im sure he can get you going in the right direction. Thanks for Watching & SUBSCRIBING

Hi Spa man where can I buy the circulation pump for jacuzzi j355? Very informative video. Thank you.

[@mohammedrafay8602]

Excellent video and shown in detail. Could you put a link for the flow switch and pump.

[@greggdesmarais9749]

Hello Spa Man! Thanks for the great videos. Trying to replace my circulation pump but the black box attached to the back of the panel that is connected to the circulation pump via a tube has another opening that was hooked up to a tube (now stripped off). Trying to fix but I don’t know what this black box even is? Attaching photos

[@spaman5440]

The black box is part of the heater and the part that probably fitting that has a hose attached to it they usually brake quite often. Thanks for Watching & SUBSCRIBING

Thanks for the great instruction on this unit!! Question: I recently diagnosed a bad recirc pump for a Jacuzzi J325 unit. I removed the pump and tested the flow switch. When I restored power to the unit, the FL1 error code came on. I removed the flow switch and manually tested it closing the switch and reading continuity. I noticed that the error code cleared, the heat light came back on, and immediately after that, the GFCI plug used on this unit, tripped. This happened after the 1/4' barb on the C3226-1A heater snapped off and water started leaking out of it. Is it possible that the heater electrical connection box could be shorted out? I appreciate your help.

[@garrettanner7963]

Thanks for the video, I just have a question for you. I was looking online, and I noticed that the FLO Could also mean that the circulation pump isnt working. If the jets turn on, does that mean the pump is working? Also, do you have any idea why the jets automatically turn off by themselves?

[@tylerford9483]

The vinyl tubing on the suction side of the circulation pump should be the stuff with the webbing in it thats rated for a vacuum. If the length of tubing is too long, the hot water will soften the vinyl tubing and the negative pressure will cause it close up on itself.

[@jTempVids]

I've had nothing but troubles with the Laing pumps lately. The first original one on my hot tub lasted a good 10 years. The second maybe 7 years. The third lasted only 1 month. The free warranty replacement just died and it only lasted maybe 16 months. Now I need a new one. Each time you can hear the impeller try to rotate and vibrate then nothing. I watched a few videos where people just change the $95 impeller. Some say the impeller gets out of balance. I've also watched quite a few videos where people just change the Laing pumps out for Grundfos. The Grundfos circulation pumps are a traditional style pump.

[@chrishaase]

Thanks for the video. I had an intermittent Fl1 error. I fixed it by replacing the flow switch. After a couple of months, the Fl1 came back and the heating stopped. The flow switch is working so I guess its the circulation pump. The question is my Jacuzzi has two jet pumps, one on each side of the pack. Do I need to pull the jet pump om the right to get the circulation pump out or can I sneak it through.

[@ValmontFirearms338]

thank you i have an FL1 error and now i can fix it sir

Thanks for your videos. I have a 2007 Jacuzzi J325. Had FL1 code for awhile and finally determined was the circ pump. Replaced it and has been working for several months no problem. The other day went out and had FL1 again. Replaced filters, used garden hose to purge air, but no sound from circ pump. Tried your screwdriver trick to test flow switch and when I touch both prongs the heater does not activate. Any next ideas?

[@sebastiancielma5676]

Did you ever find a fix? Going through same problem right now. Just hit me out of the blue a couple days after I replaced circ pump

[@CatsScienceClub]

@@sebastiancielma5676 Let me know if you find out how to fix.

[@brianjordison2910]

You should verify that the bare wire is not a ground wire but a BOND wire bonding all metal to ground. The ground wire is green and is part of the cable supplying voltage to the motor.

[@rbljackson]

talk about timing....i just developed a FLO error message on our J365. I put new filters in but problem is still there. So found your video during research. No heat because of flo error. I have bubbles coming out of the recirc pump outlet so its working. I will try to jump the connections on the flow connector like you discussed in another video. Can I change out the flo sensor without draining the tub?

[@spaman5440]

The water should be flowing out the heat outlet into the tube with a really really good amount of pressure.. You sent me a message on another video and I gave you some ideas on witch way I would go ...Thanks for watching..Let me know what you find out.

[@rbljackson]

@@spaman5440 you bet...thanks for taking the time to answer my questions in that other video. I will drain the tub to replace flow switch (if its bad) to avoid the mess. I had to fix our dishwasher this weekend, so I hope to get back to the hot tub next.

Spa Man-Thank for your videos! My circulation pump id not working- FL1 was on, flo-switch functions as per your other video. The circulation pump appears fine- it doesn't have any exterior leaks or rust. Question, How do I know it's not just a blockage? I don't want to drop a few hundred on a new circ. pump if I don't have to.

[@spaman5440]

If you are working on a Jacuzzi ?...Then remove the filters..turn the heat to 104...Do not turn on the jets...with the heat on(Red Light on Top Side Shinning Bright) and set on 104..The circulation pump should be pumping water and the flow switch should show it has been activated (Like in the video)..

I have replaced my , circuit board, flow switch, and circulation pump on my J365 2011 hot tub this past week, upon start up everything was fine and the water heated up to desire temperatures, however in a couple days I got an intermittent flo1 switch warning that I thought was due to the filters. I cleaned them and put them back but then a day or two after my circulation pump stopped working, and in turn my hot tub stopped heating. Is there anything I can do to fix it?

@spa man. I have a 2005 Cayman hottub serial numner ocn3lxd-100191700-0805. At exactly 35 seconds into this video you can see a black box attached directly to the bac of contol panel, that black box on your unit does not have any tubing but actually has a metal bolt in it. My black.box has a T and where your metal screw isni hade a male plastic screw insert with a 1/2 nipple to accept a plastic tube. Well the niple broke and when input my reach on the pastic nut that was still there cracked. Now I need a way yo get the plastic out or I need a new T that goes onto that black box but I don't know whag it so I cannot check online to either check for box or the T. Any thoughts, I have a video and some photos if need be, just tell me where ro send them. Ty

Any chance on getting or finding schematics for an LX-15 Sea Side Spa? Currently in Florida working on my girlfriends spa. I noticed it’s not heating up quickly I have that FL1 code, however the heater light does come on. I have other questions as well. Is it common to run for over an hour on its own.? I figure it’s doing it’s self maintenance. My g/f is worried it’s going to run up her electricity bill as she is freaking out that’s it 220. Also do these jacuzzi have a service line? I have a line with a manual open & close (two) valves on it. It appears to be dead end. Thank you! Bill from Peoria

[@spaman5440]

Im not a 100% sure but I think the LX-15 is built by Spas Builders and is found in many Hot Tubs.Most spa have a standard and economy mode ..you need to find out what mode it is in..(You want it to be in Standard Mode)as far as running for an hour ..Most spas when they are plugged in will run continuously until it reaches the selected heat setting after that will come on for one hour every 12 hours for filtration (the 12 hour filtration is set at the time you turned on the breaker...Example:If you turn on at 9 A.M. that is your start time.. As far as valve ? un sure what you are saying ... Hope This Helps ..Thanks For Watching. For more info call my office and ask to speak to the Spa Man.

How about unthread the flow switch from the t?

[@spaman5440]

Ive done it that way in the past.. the reason I replace the whole unit is the new one also come with the new clear plastic housing making it easier to see the flow switch activate. the other reason is I have damaged a couple when switching them and in doing so it voided the warranty because the seal was broken. Hope this Helps Thanks for Watching & SUBSCRIBING

[@TylerKohlslaugh]

HELP! 2003 j-325. I just replaced the circ pump, new temp sensor, fl1 code still. When I flip the breaker all I hear is a click, then the code pops up. I jumped power straight to the circ pump and it pumps good, then flipped the breaker to the spa and no code, heater kicks on, jets still don't work but otherwise seems normal. Also, the flow switch works as it should, continuity when shut, not when open. Is it the board? I'm lost here.

[@TylerKohlslaugh]

Also I don't recall there being a ground wire on the outside of the pump, and the new one I got does not even have a place for one I don't think. Is that normal?
