Why doesn't soap dispenser pump?

pump inoperative or feed tubes clogged. need to check the small belt; not the main belt.

most of the Bissell carpet cleaners that have the water heating feature stop pumping water at one time or another. Make sure the belt is still on the pump and if it is then the problem is probably in the heater core in the handle. Hard water deposits plug the tiny little water ways inside the heater core. Pull the heater core and take it apart and clean it with a strong scrub brush and I think vinegar works for cleaning I was told. I just use soap and a brush. Then flush all your lines with hot water. The cause is from hard water deposits or leaving the soap in the cleaner after you use it. Both will stop it from pumping water

There are a few things that can cause a Bissell carpet cleaner to not dispense water. First thing to check is the belts if your machine is a Pro Heat. The flat belt goes around the motor shaft and the pump. As the motor runs it spins the pump. This is a stretch belt and stretch belts should be replaced at least once or twice per year to work properly as they will lose elasticity even if the machine has never been turned on. The first thing to check is to see if water will spray from the upholstery tool. If it sprays but you still get no water at the floor jets then check and clean the jets to insure they are not clogged. Getting water from the upholstery tool means the pump is working ok. If not, make sure the water tank and soap tank are not empty. Even if the water tank is full make sure the soap tank is full too. I would suggest NOT putting any soap in the soap tank because that is what causes most of the problems. Put plain tap water in the soap tank and try the machine again. Hold the trigger down giving it plenty of time to flush out any air bubbles and/or soap from the pump and the lines. If you still can't get any water from to the floor jets the most likely problem is the heater is clogged with mineral deposits or soap gunk. When a machine sits in the closet for months the soap in the lines coagulates and will clog things up. Which is why if you want the machine to work for a long time NEVER put soap in it. To do a better job of cleaning put your soap and hot water into a sprayer and use this solution to pre-condition the carpets. Pre-conditioning gives the soap and hot water a chance to dissolve the gunk in your carpets, then use fresh hot water in the machine to flush the soap and dirt from your carpets. Your machine will last longer and your carpets will be cleaner and stay clean longer because you rinsed out the soap. If you try this method you will be amazed how much cleaner your carpets will be.
If you need to clean the heater you will need to separate the handle assembly by removing all the screws. First make sure the machine is unplugged. You'll have to figure out which screws need to come out, it's not too tough. The heater is inside the handle. Look at how it comes apart so you will know how to put it back together. The heater is the silver metal thing with wires and hoses. Remove the screws that hold the cover on being sure not to lose any of the tiny red gaskets. Remove the cover and clean the soap or mineral deposits from the heater core, put the cover back on and put it back together and it should work fine. To keep it from getting clogged again simply make sure you use soft water if minerals were the problem and never put soap in the machine.

The tank assembly needs to be replaced. Keep your tank handle. The other problem is your water not dispensing. There are electric solenoids and a pump that control dispensing soap and water. Take it to a repair shop for complete diagnosis before you replace the tank. The new tank is better, both soap and water tanks are in one assembly

You need to check that the motor drive belt is OK and turning freely to drive the water pump - under the flap on the right side at the front as you look at the front of the Bissell. If this is OK have you filled the cleaning bottle with fluid etc? If so you may have an airlock in the pipe from the bottle to the motor. You can also have a blockage from the pump to the dispenser nozzles and can test this by taking off the top cover and taking the plastic tubes off them to see if water comes out of the tube. You can also do the same for the tube from the tank to the pump to see if water is getting to the pump OK. Also make sure that the mix valve setting (on the left side - looking from the front) is not turned to the off position. This could also be blocked and need cleaning or replacing.

Sounds like either the pump is not working or the collection unit has an air leak.

Pour some hot water in the machine and see if the hose is clogged. Is the pump making any noise when you hit the switch like it is trying to pump?

Probably be a rubber seal leak or crack at the soap water dispenser pump.
If you can take it apart and it is the seal you should be able to reseal it with gasket seal from an auto parts store.

Could be the pump, but this model clogs up easily. You could try taking the noozles off and blow thru them to see if they are clogged or not. Other then that you may have to take it in for repair, It can be problem to find where it is clogged, if the noozles are ok that is. Unless you want to take it apart and try to find the problem yourself.

They all have problems. Hoover over Bissell, or Eureka. But it is hard to know which is better.

This could be due to dried out soap in the works below the dispenser. Try cleaning the hole, putting plain water in the soap dispenser to clean it out further. You could just put some soap in with the water. Be sure to run lots of rinse water through afterward to clean out the heating unit.
