Do you have manuals for a Bissell carpet machine model 1640-6? This machine is about 25 years old. I forgot how to set up soap dispenser

Check to make sure the tank is installed completely. Turn off unit and unplug it. Then reinstall the tank, plug in the unit, wait one minute and turn it one. Check by using the sprayer. If that didn't work call the Consumer Care at 1-800-237-7691

Your solenoid that activates the hand unit is most likely burned up. Bissell 2X machines generally last 4 to 6 uses and a solenoid burns up. This is the only machine that we do not offer repair service for in my store. It is a terribly poor quality design.
BTW, the brushes aren't supposed to turn when the machine is in the upright position.

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 put the soap solution, in the plastic gallon jug, in the sink next to your faucet...then jsut guide the short hose down into the jug.... the long hose goes out to the machine... and the whole assembly screws into your faucet.

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.

Probably plugged with soap. Try to clean the hole under the shampoo dispenser. Put plain water in the dispenser and hope it gradually cleans it out.
