No soap, soap pump belt is very loose. How to replace?

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.

You need to replace the pump belt. This is the belt you need:

I wasted a lot of time following the expert advice to repair my unit by taking the cover off of the main unit and using compressed air to blow out the lines. The problem turned out to be in the lower panel of the handle (4 screws to remove). The heater is a large block of aluminum with a stainless cover held on by screws. The lower nozzle of the heater was blocked by water/soap reacting with the aluminum while in storage. Blowing out the lines as recommended with air compressor just warped the stainless cover resulting in time spent flattening this back into shape.

I would recommend the following steps:
1. Make sure that fluid levels are up in both the supply water bladder and the soap dispenser.
2. Pry off the left side access cover and ensure the pump drive belt is still in position. Switch the unit on and see that the pump is spinning.
3. With the unit plugged in and the handle laying flat on the floor (using the foot release lever) , remove the clear bezzel over the red impeller, switch the unit on, and pull the trigger for soap. Liquid stream should shoot straight up past the impeller. If not the lines are plugged somewhere.
4. Unplug the electric power. Remove the four screws and remove the lower handle access cover (with the red light in it).
5. All the fluid lines are clear plastic so you can identify which have fluid movement.
6. Disconnect the line from the soap activation switch (pliers on the squeeze hose clamp) feeding the heater (large aluminum block). Blow air (with your mouth NOT the air compressor) into this line and see if fluid movement is observed in the clear plastic lines. A little tentative about soap in your mouth, use a turkey baster filled with water). I saw no movement of liquid. Nozzle exiting the heater blocked.
7. Remove this hose and use a small drill bit to twist the debris loose. You may elect to remove the heater shinny cover for better access. Gaskets are reusable. Blow thru the hoses again to assure blockage cleared.
8. Button unit up.
9. With the clear bezel off and the red rotor exposed, plug unit in, soap and water supplies in place, switch on power and pull soap trigger. Should see vertical stream. Mine was about 5 inches initially then jumped to about 10 inches high. Knew blockage was cleared.
10. During shampoo operation if soap stops (red impeller stops spinning) first check fluid levels and fill. That doesn't work, I unscrewed the clear bezel and pulled the soap trigger with the unit switched on. Less than a second vertical stream appeared every time.
11. Now you know how to fix and achieve continuous operation.
12. The unit must be thorougly cleaned before putting it away for storage to prevent the reoccurance of the blockage in the heater. After following the manufacturer's instructions, by flushing (operating the unit) with clear water in the bladder and the soap dispenser, I did one final thing. By removing the fresh water storage/collection plastic container, a black round fitting is exposed that channels the water from the bladder into the spray system. I used a length of automotive heater hose that was the same diameter as the seal on this fitting (turkey baster with bulb off will work) and blew hard while the unit was switched on and the clear bezel was off. One last big blast of water spewed from the unit. This cleared all the lines from the bladder through the pump, switch, and heater and blows it out just prior to the spray nozzles.

This is long but specific.

Not so technical, take each step as presented.

Good luck.

If it is the flat belt that broke, that is the pump belt, the pump can't work without it. To replace the belts, turn the unit over, remove the red holder, has one screw, pull it out, then the brush roll will come loose. You can replace the belts thru that opening.

There is a panel on the side for belt access, open this and inspect your belt. Usually replacing the rubber belt will fix this problem, as the belt from the main motor is what drives the water pump unit. (The cogged belt in the front is what drives the brushroll, but if the rubber belt isn't functioning properly the brushes generally won't turn either.)
If the rubber belt seems ok and the brushes are turning either you have soap clogging the lines, or your pump has gone bad.

Flushing out the water lines can help clear a soap clog, but to effectively do it requires disassembly of the lower chassis. Both this procedure and pump replacements in these units are a nightmare because all of the rubber hoses running around in the machine have a tendency to get pinched closed on reassembly, so if you do disassemble your unit, be very careful to align all of the hoses so that they are not crimped upon reassembly.

if you are getting power to the pump then it has to be something stopped up take the lines loose from the pump and see if you can blow through them if not its stopped up if you can you might not be getting power to the pump use a volt meter with it on and pluged in to see if you have power. at the wires to the pump and make sure you dont get an electrical shock be careful have the meter set on 110 V AC. try to blow through all the relevant lines to check for stoppage.
