I started shampooing some carpet yesterday, and our shampooer was leaking from the bottom, so... I took it apart.
After a bit of trial and error, I discovered that the side port/valve where the water/solution hose for the upholstery tool attaches to the machine was the source of the leak. It is called a "quick disconnect assembly," and I found the end cap popped up on one side caused by a broken locking tab on the inside of the part. I could put my mouth on the inlet tube, blow, and hear air passing through but when I pushed the end cap down as it should be and blew through the inlet tube, no air would pass through. I searched online for the part, but it is not manufactured anymore, so I decided to try and fix this one. I have some black epoxy and clamped the part so that the end cap would be seated properly, then mixed up the epoxy and filled in the slot where the locking tab would be. I also epoxied the other side for good measure even though that locking tab was intact. Now, I will have to wait a day or so, put it all back together, and see what happens. If my "fix" doesn't work, then I will just plug the hose that connects to the "quick disconnect assembly." I won't be able to use the upholstery tool but would still be able to use the machine for cleaning the carpet. We have a "Little Green Machine" for upholstery anyway.
