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.

Thanks,

No carpet spray


That means that you need to replace the pump belt. Here is a link to the belts you need and the manual:

Won't spray wate rwhen you press trigger.


When the water won't dispense that usually means that the pump belt is usually stretched or broken. Here is a link to the belt you need and a manual you can view:

This may be caused because the pump belt has stretched or broken or the pump is seized and will not turn. Remove the pump belt and turn the pump rotor with your fingers to see it turns freely. If it does then the pump should be OK but the belt may be stretched and will need replacing. If the unit does not spray after changing the belt then clean the spray nozzles at the front of the machine and make sure that water flows to the nozzles OK. You can check this by temporarily disconnecting the nozzles from the plastic pipes.

Main causes for no spray.

Bladder may be empty.
SmartMix Bottle may be empty.
The Filter may be clogged.
Tanks may not be seated properly.
Pump may have lost prime.
The Pump Belt may be broken.

2 front jets are blocked. This is a common problem. When the machine is standing for a while the detergent turns to a gel causing the blockage Lay the Bissell on its side then where the water comes out of the jets at the bottom of the machine unblock them using a pin to poke through the hole in the centre.

Try running hot water through the system with no detergent to empty out all the residual detergent. Keep running hot water through the system by pressing the button you press for it to spray the water do this for about 5 mins and keep swapping the water for hotter water as it starts to cool doing this 4 or 5 times might solve your problem if not get the tools out and start looking for the blockage. Do this once a month to ensure that the pipes and jets are kept clean and free of any detergent gel build up.

Machine suction works but will not spray liquid. Belts are ok but are not turning. Shaft gets hot and there is a burning odor.

My bissell proheat 12 amp will not spray water on to the carpet,nor will the hand tools spray water?


The water is pumped via the belt that drives the pump. Remove the belt pump on the left side of the unit using a screwdriver and prying upward in the slot in the rear of the belt cover. The belt cover has holes in it. Check to make sure the belt is not broken. If it is replace, about $3-4.

Good Luck
