Question about Bissell 7901-1 ProHeat Scotchgard Upright Wet/Dry Vacuum

Bissell Pro Heat gives no flow

I confirmed that tubes aren't clogged and that the belt's not too loose.  I took out the pump and blew into the suction and turned the rotor-- can't get any air through. I turned the pump over and blew and got air through.  How does this thing work?  and why doesn't mine.  I just had the pump replaced at a service center.

Re: Bissell Pro Heat gives no flow

Check the heater in the handle to make sure it isn't clogged up where the tubes hook to it. When you put the top back on, make sure the tubes are routed correctly so as not get pinched by the cover. The smart mix valve needs to be on the water setting and make sure that the piston is on the bottom of the smart mix knob. Is the seal at the bottom of the tank on the tank and not sitting in the hole or missing, tha flow indictor cap is leaking air or may even be on too tight.

Why is there no suction or extration of wateron my bissell pro heat pet ?

Your filters may be clogged. The User Guide states that filters are to cleaned after each use. To clean them Turn the Flow Indicator Cap counter-clockwise and remove it. Lift out the rotor and filter. Clean filter and reinstall in reverse order. There is also a Lint Filter on the Hot Water Tank Cap that you should clean as well. When these get clogged they seem to do funny things. Hope I helped.

Bissell pro heat wont spray water

Hi, it's Allie from Crucial Vacuum!

Your Bissell ProHeat 25A3 may have stopped spraying water for several reasons. Make sure the bladder or water tank of your unit is filled with water properly and that the 2-in-1 tank has been placed properly.

If the water tank/bladder is filled and the 2-in-1 tank is placed properly, your unit's pump may have lost prime, to check this turn your unit's power off and hold spray trigger for 30 seconds. Turn the machine back on and check the spray flow.

Another thing that may not be allowing your unit to spray properly or spray at all is having a clogged solution filter and may need to be cleaned.

Last, your unit's pump belt may be broken. To replace, turn off your unit and unplug from any electrical outlet. Use a flat head screwdriver into the slot of the belt access door to release where you should have access to your unit's pump belt.

Bissel pro heat cleaner won't expell water -- seems no suction

The reason that it won't expel water is because your pump belt is stretched and worn. You need to replace that belt, it is pretty easy. Here is the belt you need:

Bissell Pro Tech Pro Steam Cleaner - no suction @ pump

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.

Good luck!

Bissell PRO Heat Steam Cleaner is not dispensing the water. I took it apart and cannot find any obvious issue with it i.e loose tubes, connectors etc.

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 knob. Pump is bad. Try running a mix of vinegar and water to see if that unclogs the lines.

Brush is not rotating.

Turn the vac over, remove the access plate, covering the brush roll, 2 to 4 screws. Brush roll part number is 2032032if you need it, belt is a Bissell Style 7. While you have the brush roll off, check in dirt inlet to see if it is clogged, also check the hose to see if it is clogged. You won't feel suction at the bag tube, it has to have a bag on it and the lid closed before it will create suction.

No flow and no suction

Check to make sure that the seal under the buckets are on the bucket and installed correctly. There should be a rubber gasket between the clear window and the bucket, there at the top. When the top cover was out back on, were the tubing routed right as to not get piched when the cover was put back on, also the piston underneath the smart mix know is on the bottom of the knob, and that the smart mix knob is in the water setting. Another is the cap for the flow indicator is leaking air or e=ven be on to tight. One other thing is to make sure that the heater in the handle asm. is not plugged where the tubes hooked into it.
