Question about Bissell 9400 ProHeat Upright Wet/Dry Vacuum

Bissell Proheat 2 solution tank

I bought the machine Oct. 2007. The solution isn't emptying from the solution tank when I use my cleaner. I called the Bissell service number for help and they had me try these things: 1-When depressed, solution does come out of the x-valve on the cap of the solution tank. 2-The cleaning strength dial was set to normal clean and light clean during my cleanings. I was then referred to a local repair company.
Do you have any suggestions for me to try to fix this at home before taking it to be serviced?

Re: Bissell Proheat 2 solution tank

First make sure the solution bottle is seated correctly and the machine solution inlet is free from any debris
try the hose part of the machine,
See if water comes out of the hose ; Set the dial to heavy traffic, then put a pencil mark on the solution bottle level with the solution liquid ,
See if the solution level goes down
see if water is coming out of the spray tips under the machine
The spray tips could be blocked .

How To Fix Your Bissell Carpet Cleaner When Solution Doesn't Spray

If you have a Bissell Carpet Cleaner, and you're machine is not spraying water on the floor, there are several things that might be causing this. Here's a list of possible problems that might be causing the machine not to spray water:

It may be a problem with your pump belt. Bissell Carpet Cleaners use a belt that powers the pump to spray solution out. There are also a few other possible issues, but as a Bissell warranty station, the belt going bad out-numbers all other problems.

Remove the belt access door and inspect the pump belt to ensure it is not broken, worn or stretched. You may also check the belt by turning on the power and watching the brush on the bottom of the machine. If the brush rotates the belt is not broken.

If your belt is worn out or broken, here's a direct link to that belt on our website:

Here's a great video that will show you how to check, and replace the pump belt on your ProHeat carpet cleaner:

If this was not the problem, here are some other things that you may check:

  • Make sure there is liquid in both the Tank-in-Tank and the SmartMix bottle. Both tanks must contain fluid or the machine will not spray properly.
  • Check for proper placement of the o-ring on the SmartMix Cap Insert (some o-rings are detachable and need to fit over the straw; others are molded to the cap).
  • Check for liquid in the base of the machine where the SmartMix Bottle sits (SmartMix Reservoir). If there is no liquid in the reservoir, the neck on the SmartMix Bottle may be undersized and the cap will not make proper contact with the unit. If there is no liquid present, you will need a replacement SmartMix Bottle.
  • Check for the black or red tank gasket on the SmartMix Bottle Cap and on the bottom of the Tank-in-Tank Assembly. If gasket is lodged in base of unit or has been lost, reattach gasket on auto-load or order new gasket if appropriate.
  • Check the valves on the bottoms of the Tank-in-Tank and SmartMix Bottle to make sure water/solution will come through when the "x" valve is depressed. (Bladder or SmartMix bottle may be empty or the valve may be blocked internally.) Use a soft-bristled brush and hot tap water to clear any debris. Replace autoload assembly or cap/insert if necessary.
  • Check if the small rounded window tabs on the top edge of the Floor Nozzle are locked in their mating slots on the base of the machine, and not inadvertently lifting the tank up out of place.

If these suggestions have not resolved the problem you are experiencing with your machine, you might want take your machine to a local BISSELL Authorized Service Center. I really hope that this information was helpful to you. If you find what's wrong with your Bissell and have specific questions about how you can fix it, please just let me know and I'll be happy to walk you through step by step to fix any problem you may have on your Bissell.

My formula tank is not emptying on my 8910 proheat eurka cleaner

Make sure it is on heavy traffic on the selector set. You may find it is on Clear water rinse. FYI you will find your machine will clean better and your carpet will be cleaner if you use a weed sprayer and mix your soapin it. Just spray it down fairly heavy and let it set for 10 minutes. Then just use straight water in both tanks and you will be amazed. It is like a lasagna dish if it soaks for a while it comes cleaner easier.

How to unclog a bissell proheat turbo carpet cleaner

proheat 9300

Remove the water tank. You will see 2 red tabbed plastic spray tubes.(where the spray comes out if not clogged) Pinch the clips to remove from the machine. Then you will need to pinch the hose clips to remove the red tabs from the hose. Clean out those red spray nozzles. Next step: have a towel ready and fill the solution tank with water. Put the solution (not water) tank on to where the water tank would go. Place the machine selection knob to rinse/wet only. Now with towel under the hoses that you removed the red tabs. Turn on the machine and pull the trigger to activate the water. You should see water flow out of the hoses that had the red tabs on them. If not, release and pull again the trigger several times. If only 1 hose has water coming out of it then block the one that works and try the process above again to de clog the one that isn't working. Good luck.

I have a Bissell ProHeat Turbo 2x, it isn't mixing the water & cleaning solution and isn't spraying. What do I do?

Isn't Spraying:
Possible Problems->Solutions
-Water Tank may be empty-> Fill Heavy duty bladder with hot tap water.
-Formula Tank might be empty-> Fill with Bissell fiber cleansing formula for cleaning.
-Tanks may not be seated completely-> Turn power off and reset the tanks.
-Pump may have lost prime-> Turn power off, then on again, wait one minute then depress the trigger
