SOURCE: Bissell 7920-E; No spray.
I have a similar problem and `phoned Bissell support. They told me that no spray is either a failed drive belt or a failed pump. I suggest you remove the belt access cover and see if the belt is intact; if so rotate the pump using finger pressure - it should rotate easily with no unusual noises.
If this is all OK, fill the bucket and the mix bottle with warm, clean water. Turn the machine on and with the handle upright press and hold the trigger for about 2 minutes. Hopefully you should see a spray and both the bucket and bottle will reduce in volume. If not you have either a blockage in one of the tubes, the trigger valve needs adjustment or, worst case, the pump has failed.
Hope this helps.

The problem was a clogged heating unit which is located in the lower handle. There are two clear hoses going up the inside of the left leg of the lower handle that go to the heater and to the in-line water switch all within the lower handle. I unplugged the metal heating unit water lines and electrical connections (label the connections as you take them apart if you have a hard time remembering things...there were seven connection in all be it water and/or electrical). Removed the heat unit out and then removed the 6 screws holding the heater cover. Inside was a white powdery pasty debris (lime deposit ?) and the water path was clearly blocked in four different places. I cleansed the water trough with a little water and soft toothbrush and several toothpicks then reassembled. If you need new washers go to Orchard or ACE hardware. Take the old rubber washers(they are red) with you for comparison. I didn't need new washers...I just gently cleansed them. I immediately ran clear water through the machine and actually cleaned the carpet with a water rinse only. Will go back and finish the carpet the right way tomorrow. I had only used my machine three times before this happend over a three year period. A friend told me to always rinse it two maybe three times with clear water after using it and before storage. This took me exactly 42 minutes to disassembly and reassemble. Cost savings is several hundred dollars since I have a 5 bdrm house and would need a professional cleaner to do the small dirty traffic lanes all around the house.
