Water leaking out from bottom of 7901

I have a 7901 steamer. Water leaks out of the valve uner the bladder tank.Appears to be leaking out from the part that is attached to the body itself. (not from the part on the bladder tank) I took the thing apart and the spring -loaded part on the bladder tank seems fine.Does the other half of this have records of leaking. I filled the other part up with water and it does not leak by itself. When i blow into it the water comes out of the end normally.I was wondering if the "pressure seal" might be the culprit here.Can you purchase this part seperatly. Any help would be great. 3 kids and a dog want me to fix this thing soon. Thanks,Jim

That part can go bad, but I have found more often the a water line came loose. Take out the 6 screw and the flow indictor cap, remove the top, then inspect that area. If you find what the problem is, fix it then when you put the top back on, make sure the piston is on the bottom of the smart mix valve and that the knob is in the water only spot, then push the top back on. If you need to replace the auto-load receiver, the part # is 2140710 and you can order from a local repair shop.

How do I cycle the valves on the bottom with the eraser end of a pencil on my hoover dual vac shampooer


The center part of the valve (stem) pushes up (spring loaded) to release liquid. If it leaks it can (and should) be replaced. Also, check the black valve seal (conical shaped ring around the outside) for cracks or splits as this can contribute to leaks. The entire valve assembly (similar to photo) should be replaced to solve both issues.

How to fix dirt ***** easy steamer deep cleaner, it is leaking water?


Hi there! Check the clean water tank valve to see if that is where the leak is coming from. If so, your clean water tank will need to be replaced. If the leak is coming from somewhere else we recommend taking the cleaner in to a Dirt Devil authorized service center for repair. I have included a link where you may locate the nearest service center to you. Hope this is helpful. If you still need assistance feel free to reach out to us here on Fixya, Facebook.com/dirtdevil or Twitter @DirtDevil.

The Clean Water Tank is a 2 stage tank. As the clean water leaves the Tank the flexible bladder allows the dirty water to enter. Dispose of the water in an area outside or a utility sink.

Let me start out with an apology. I did not ask my question very well - and you did not answer it as I needed.
If you wish, we MAY be able to communicate in your native language. We can do most indian languages, Turkish, Ukranian and some Russian - as well as Spanish. If any of those are easier for you - please feel free to use any of them.

The Machine storage tanks are 2 - one clean water, one dirty water.
I understand that, when OFF, no leaks happen.
I understand that when on a leak comes from "the side". Also, water comes from the bottom.

So, water comes out near the bottom brushes (even without trigger). Then, with trigger, MUCH water comes out near bottom brushes. Am I correct so far?

Water out the side concerns me. I am guessing that the bottom of the clean storage tank may have a small leak.
I am also guessing that the trigger valve (located in the small opening behind the black rubber seal that the clean water tank rests on) is not closing all of the way - or is broken (cracked).

Can you please remove the clean water tank and inspect the trigger valve with a torch (flash light). Can you see it open/close as you operate the trigger? Is it broken, cracked, or dirty?
If yes then it must be replaced. If no, the the storage tank is bad and must be repaired.

You inspect all of these things and you should be able to determine the failure. THEN, I an help you repair the failed item.

Sounds like either the pump is not working or the collection unit has an air leak.

Rubber valve at bottom of blader tank


It is called the (#69)auto load asm, part # 2107041. It would be wise to replace it, It will come as one piece. Is the bladder ok? You can call Bissell and maybe buy the part thru them or they can tell you where to go to get it(800) 237-7691 ) .

Will water squirt out the hose? If it does then the heater in the handle may be clogged and not allowing water to flow. The heater is in the handle. There are a number of things that can cause your problem. If no clogged heater and lines, and no water from the hose, then the pump or pump belt maybe bad, the cap for the flow indictor is leaking air and not sealing, the gasket at the bottom of the tank isn't on the tank, either missing or sitting in the hole in the base where the tank sits.

Does water squirt out of the hose nozzle, if it does, then check the heater inside the handle asm. Make sure that where the tubes hook up to it are not clogged. If water doesn't squirt, check for the seal at the bottom of the tank, it needs to be on the tank, not in the hole. The flow indictor cap is leaking air or maybe is too tight. If you had the top cover off, make sure that the tubes are routed right so as not to get pinched when the cover is put back on, the smart mix knob should be in the water setting and that the piston is on the bottom of the smart mix know. Pump is bad.
