Question about Vacuums
Hi There, Problem - no water or soap flow when depressing the trigger. Check belts - both ok! Lines do not appear to be clogged however I did blow some air though them. Pulled lower top cover to expose pump. Pulled line off pump - no suction? Should I get noticeable suction from the pump? any thoughts?
Take a look at the Service Center Repair Manual (courtesy of Bissell New Zealand):
There's a (basic) diagnostic routine for cleaning solution flow (page 7). However, there's a step that's (somewhat) left out. If you follow the diagnostic and get no spray, then try to spray with the hand-held upholstery thing. If:
1) you can spray cleaning solution with the hand-held upholstery thingie, and
2) there's no pinching of the lines at the base of the unit,
...then your heater block is probably blocked. There's a Lower Handle Disassembly guide (page 20) which you can follow to get at the heater block. The input port on mine was blocked with lime, and quite clearly so (I live in an area with pretty heavy water). You can also take the heating block apart (page 8) to better clean out the flow channels, and apply some descaler. I suppose you could also just recirculate descaler through the input and output ports of the heater block, but I wasn't exactly equipped to do so.
If you can't spray cleaning solution from either the upholstery thingie or the main unit, you probably need a new pump. Word of advice: get the one with the METAL PULLEY on the end. The old ones had plastic pulleys which often failed or deformed to uselessness after a while. Since the pulley wasn't replaceable, you had to order the whole pump assembly. Bissell maintains a list of service centers in various countries / cities which can either repair your unit for you, or, considering the name of this website, sell you the parts.
