Fix your smoke, snow machine, steam mop solenoid pump.

[@twocvbloke]

I bought my smoke machine (a cheapy with the pump rammed into the built-in tank) off ebay with a dead pump, wasn't actually dead, just worn out, took it to bits, thought I'd test it while it was open, the piston shot across the room and to date I've still not found it... :P Never needed the machine, I'm just obsessed with electricals... :P

As long as you're looking for it, you'll never find it. The trick is to put it out of your mind, convince it that you're no longer looking for it. Then it will suddenly appear somewhere you're sure you couldn't have missed looking before.

[@richardclayton1374]

This video has come to my rescue for the second year in a row! Last year it was a blockage, this time that pesky o-ring needed a trim (and when my Dremel attachments didn't do the job, my wife's electronic nail file was just the ticket!). Thank you Clive!

[@JeffandJake]

Clive, I have watched your videos for years out of interest and curiosity. I recently was working on my dehumidifier whose water pump was not functioning properly. I disassembled the machine and found a nameplate on the solenoid pump which I combined with a few key words on Google only to find your video. I should have known you’d have a video on this very topic. The pump I have is similar in construction but not identical. The operating principle is the same. I had to get this pump operational today so I simply cleaned the gunk and lightly lubricated the culprit o-ring (I know eventually the o-ring will swell a bit when in the presence of petroleum oils) and it worked. I appreciate your videos and all of the interesting stuff you’ve put out over the years. Thank you.

[@gleaminx]

Thank you for this video. Due to your full tear down I was able to determine the plastic housing in the donut hole of the solenoid connecting the piston to the fluid input nipple was broken. I ordered the same pump in this video for my Froggy's Fog F4 Fobble machine. FYI - for those who have my same issue, read on. I had to reuse the black cone shaped o-ring from the output side of the original pump to seal the existing silver metal tubing to the new gold colored nut. I wired it from red to brown and black to blue using Scotchlok UR2 butt splice connectors. I left the diode on the wire. She runs great!

[@mobettaspice]

Thank you. You gave me the confidence to examine my pump and fix the problem. Now it’s working again.

[@Bickley68]

Excellent, thank you so much. I used this to fix my steam mop with a 30DCB in it. I'd already dismantled everything else and descaled it and came to the conclusion the pump was the only other thing. It's now working like a dream.

[@Erasmuspipebagger1]

I brough my haze machine home (which is essentially a low output smoke machine and a high output 240 volt fan at the front on a 45 Deg (ish) angle, which disperses the smoke quickly so it doesn't look as frightening when it comes out of the machine) and I was faced with exactly this problem : I knew the pump wasn't working. Lo and behold your channel pops up and the fix of the first o-ring being flattened was exactly the problem the pump was all the way in one direction and wasn't coming back enough off the buffer. Popped in a 6 x 1 mm o-ring (I service air rifles, so I have 1000's in zip lock bags) and would you believe it the bloody thing works again. Now I'm going back to making more Joule thieves (it feels like somehow I'm saying thank you, with the added bonus of keeping the few quid I have in my pocket). Please keep up the excellent work, your channel keeps me going when all around me have failed.

Brilliant video. Exactly the same pump as in a floor mop that I'm trying to repair. The whole heater was blocked with scale. Ive cleaned it and descaled everything. It worked brilliant at first but then stopped. I rechecked and no blockages so i took the pump apart, I can hear it trying so I'm at a loss. Now seeing your great video Im going to bench test it and check that seal is not too tight. Thanks.

You can get replacement o-rings. A dab of silicone grease can get things going again.

[@markgreenbaum9680]

I've been rebuilding fog machine pumps for a few years and this was a very helpful video. I didn't know the little red O-ring was subject to swelling, and I don't have any on hand. I was able to get my existing pump running enough to verify the heater wasn't clogged but I'm not getting the volume of fog I expect from a 1KW. All the other parts look good so I have to assume the tiny red O-ring is the culprit. Thanks for the "class".

[@bigclivedotcom]

If the heater core is furring up then white vinegar may clean it.

[@tachmonite37]

WOW! You are the man! I had a steam mop just sitting around for over a year because it wasn't producing any steam and your video was just specific enough to help me fix it. One of the springs was not lined up properly so I think the pulsating part wasn't moving as it should. THANKS for this video.

[@SigEpBlue]

As long as you thoroughly flush it with distilled water afterward, there's no harm in using an acid for cleaning. I use citric acid, as it's more aggressive than vinegar, and less expensive per unit volume if you know where to look. Also, it dissolves solid deposits MUCH better when it's HOT. Thanks for the tear-down and explanation of how it works, Clive! :)

[@amseek94]

Man I wish I had found your video before brute forcing my pump open. Had to cut slots in the crimp of the housing then pry open the crimp. Oh well, luckily the crimp didn't need to be water sealed tight 😊. Thank you for another wonderful, easy to understand video. Love your stuff 👍

[@williammchugh4361]

Thanks, had a fog machine that stopped working after a single season again. Pump hummed but didn’t work. Disassembled and it turned out to be an issue with that very small gasket you were talking about. In this case, the gasket was rubber and didn’t allow proper travel of the metal piece. Scrapped the inside out a little in place with a utility knife. It started working again. To test, you remove this gasket put the pump back together without it and see if it runs.

[@julianmartin7985]

Excellent video. I had issue with my pump which is very similar. Yes the O ring had swollen preventing the plunger to move back and forth. I too had problems sourcing the correct O ring. I found one that was slightly oversize on the inner diameter and slightly larger on the outer diameter. When fitted it was too tight on the inner. I gently slid the O ring over the shank of a drill bit and with a needle file ran it over the outer whilst spinning in a cordless drill until the fit was perfect. It's now working better than when the smoke machine was new. Thanks again for the tip.

[@bigclivedotcom]

Another thing that helps is a dab of silicone grease on the plunger.

[@georgebraud]

Great video. Thanks. In my case, I will need to scrap my OEM pump and buy another. My OEM pump is made of brass instead of plastic. The spring plunger w/ the small rubber head that goes in the brass hole was stuck. The only way I could get it out was to force 100PSI of compressed air from the other side. Once out, I had a hard time to get it back in the hole. I tried sanding the inside of the brass hole w/ 320, 400 and 600 grit sand paper. I cleaned out much of the build-up but the plunger would still not move freely inside that hole. I tried the pump w/ the plunger stuck at the bottom and I tried it without the plunger installed. No luck. Amazon, here I come.... Anyway, thanks for the time you spent putting this video together.

[@bigclivedotcom]

Thankfully, the pumps are pretty common and cheap.

[@Bullfinchman1]

Well i took it apart again and sure enough the solenoid plunger was sticking on the rubber seal. I flied the inner of the seal but although it improved it was still sticking so I used a blade and gently scraped the plastic where the outer par of the seal goes. Its working perfectly thanks. Its an H2O Steam Cleaner. Thanks again.

[@amseek94]

Word to the (un)wise: If for some reason you brute-force this thing open (ie remove the white plastic cover you normally unscrew the right angle shaft from), when putting it back together the white cover wants to be just so slightly above the contact spacer/stand, about a 16th of an inch. It's also critical that the right angle shaftt is directly in line with the hose connector on the other end (check all sides), otherwise the solenoid inside with either just hum or rattle like mad. I found you can put a slightly thick washer between the stand spacer and the white cover. That will help maintain the correct gap. If you have the gap too small, you won't be able to screw in the right angle shaft and it will keep slipping like it's stripped (it's plastic threads so when push cones to shove, they let go). The diameter of the white cover is larger than the center brass tube and you need this center. The diameter of the right angle shaft will help maintain the correct centering once screwed in but getting the gap, direct center and overall tightness is a science to get it all just right. Slap some alligator clips on a standard 3prong household wire and test your progress in the sink. (Take pictures of which wite goes where - ground is the wire plugged into back of pump if it exists, wire with inline diode goes to hot (black) other wire to white (neutral)). Or it might work either way. I didn't check. Best scenario? Watch bigclive videos before you start tearing things apart the wrong way 😂

Hello Clive. I hope you are well. I've been given some of these that don't work and all have been a case of blockage. I'm sure my method of clearing it would not be "Clive Approved" but worked. I had no clue the pump would disassemble that easily. Thanks and have a great weekend.

[@bigclivedotcom]

I'll guess forcing fluids through it? That works.

[@ATMAtim]

Pumping fluids at enough pressure to force cleaner to bypass the 2 check valves. There's a magic point in which the valves neither block or pass and that allows water to chase enough blockage through to clear it up.

[@apexmike849]

When servicing hot pressure washers, one must descale the heating coil, which is a coiled steel tube, forming a drum shape into which diesel is sprayed ignited and air forced in with a fan. It gets very scaled quite quickly - a bit like a monster kettle, but angrier. We use hydrochloric acid for this task and it is a pretty scary process, as you are basically dealing with over 100°C steam/water at around about 2500 PSI and so you can imagine what happens when we pour in HCL to this mix! By comparison, a small bit of vinegar in a small copper pipe, well...

[@patrikstaron]

In my case the pump was stuck, but I just opened it up as in this video, cleaned it a bit and then tightened the valve part, but maybe 3/4 way through. Turned the pump on and it rang like crazy. Then I disconnected the pump and tightened the valve a bit more, turned it on, it worked and was more quiet. Then I disconnected it again and tightened it fully. It works.

It sounds like the o-rings are the biggest problem in these machines, almost a design defect. Couldn't there be an improvement to the original design by the pump manufacturer, or a repair option, using some kind of "self-lubricating plastic" such as Teflon or Delrin for the o-rings?

[@chrisPbacon_1]

this video came right on time, had a zr44 that needs a date with the screwdriver this weekend...

[@BlueKitsuneSakai]

You can also try to boil the o-ring in clean water and in most cases it'll return to its original dimensions. I use that trick for o-rings that touch fuel in automotive applications. Just don't let it touch the bottom of the pot or it may melt to it.

[@bigclivedotcom]

I'll have to give that a go.

[@PaulSteMarie]

That inlet check valve: is it opening via water pressure or inertia? I'm guessing the latter, since the pump is drawing water up into the mechanism.

[@bigclivedotcom]

If there's a dribble of liquid then it's possible that an electrolytic capacitor has failed and leaked. If it's a lot then a possible scenario is that water from above the ceiling has entered the lamp in some way and caused discoloration and corrosion.

[@utahsirens]

I'm thinking its an issue with the capacitor. The lamps were originally bright white, but after about a month, the lamp decreased in brightness and started to glow a warm yellow light. I replaced it, and the new lamp has the same issue.

[@bradheuser5949]

At 13:04 frame, you can see a ~ 5mm straight "slot" on the metal piece. When pump is activated in our fog machine, water leaks out of this "slot". Other than water leaking from this spot, the fog machine works fine. Any thoughts on why water is leaking here? thnx

[@CyberlightFG]

I repaired my smoke machine by using a better pump. What you got there is the cheapest available. It never failed since then. Would you show us a professional pump? Sometimes the heater gets clogged, too. If you use a thyristor you don't need the diode.

[@jhsevs]

The diode is interesting, why don't they just use the negative half of the sine wave to pull the plunger back? There's probably a good reason for that?

[@bigclivedotcom]

The core isn't magnetic. It would be attracted in on both halves of the waveform.

[@kilrahvp]

Core would then need to be a magnet, aka a lot more expensive.

[@AM-yj5yc]

My personal guess would be energy consumption. Having the negative half move current too would double power consumption and isn't neccesary since a spring does the same job as a passive device requiring no power. Not an engineer, but that'd be my guess.

[@picobyte]

@@bigclivedotcom remove the diode. More smoke. Less runtime per cycle? Maybe full wave just is to fast for the piston to get back to start position.

[@someguy2741]

@@picobyte Not the issue. The magnet would not turn off. The piston would stay attracted because the magnetic field needs time to collapse. The solenoid would not have time to cool off either and the coil would burn out. You could have two coils and suck the piston to each end of its stroke using coils at each end but that doubles the cost when in this case a spring is adequate. If you were pumping something thicker you maybe could use the force generated from the other coil instead of a spring. FYI, solenoids are disturbing powerful little things, and simple, and cheap. The tradeoff is one direction power only. If you decide to play with one.... watch your fingers :p

[@Dontknowme81]

This helped a ton, that’s a lot!

[@4DRC_]

Will this method work for the smaller 12vdc 4.2 watt pumps on eBay as well?

[@jamesg1367]

Only one way to know. Buy one and take it apart! FWIW, a DC pump needs some sort of oscillator to switch the coil. And at 12V it will have a finer-wired coil with more windings. Otherwise the design is presumably very much the same.

[@simontay4851]

I wouldve thought there would be less windings at 12V. The 240V primary of a transformer has more windings of thinner wire than the low voltage high current secondary. Are solenoids not the same?

[@bigclivedotcom]

You can often open them and clean them, but they are based on a magnetic rotor and impeller. If the cover comes off the impeller and core usually slide out.

[@netpilot5]

I've got a 12VAC impeller type pump in my cat fountain. My water's pretty hard. Tried cleaning it with vinegar and couldn't dissolve all of the scale that built up on the shaft that the magnet rotates around. Finally gave in and carefully soaked the motor innards with a household descaler called CLR and used a fine pipe brush (with gloves, eye protection, ventilation, etc.) to work on the harder deposits. Has worked like new after that. Does anyone know where I can get a submersible impeller pump that pushes maybe 50% - 100% more water than the garden variety one found everywhere? The stock 12VAC 200ma one that I have works as designed to aerate the water and doesn't splash much, but my cats like to drink from the falling water. The water flows so slowly that they lick the spout rather than the stream. I want to get the stream to be a bit more robust. Specs for small pumps are almost never listed online. Any ideas? Edit: spelling.

[@jamesg1367]

@Simon Tay -- This isn't a transformer. Unless I am severely mistaken, a lower voltage requires more windings to produce an equivalent current and consequent magnetic field.

[@voxmanish]

If you wire the red and black wires directly to 110v, on a working pump, will the pump vibrate rather obviously?

The pump often has a diode built in or inline with the cable. So it will run if it's designed for 110V.

I've stripped my pump down on bubble/smoke machine. Beamz SB2000LED It's model is 30dsb-zjf pump 50hz 18w. My machine works for a while then the smoke seems to stop. Is it the pump or could it be the heater element not heating the fluid? The pump seems to work though. Any thoughts?

If the pump is pushing through liquid then the heater block may be blocked up. It may be possible to dissolve any blockage with a weak acid like white vinegar in water. Complete heater pipe blockage is a fairly common machine failure.

@@bigclivedotcom I'll try white vinegar through it. I've flushed through with distilled battery water after use. Frustration is I've only had it out twice to use and after about an hour the smoke stops and it's just bubbles blowing... Making it an expensive bubble machine lol If I get a new pump off the net... I see they say 500w 900w etc. Does it matter which you get as mine is a 2000w unit.

Hi Since a week I work to bring steamer cleaner back to life. All you said was mega helpfull ,expecially the O-ring which cause pump disfunction. Also you said it's difficult to find replacement. I think I have found solution how to safe it by making it functional. If you want to know we can talk. Regards Miro
