It sounds like you either have a clogged nozzle or one that is too small for your pump. At lower speeds the pump is pumping less gpm. So your unloader valve does not cycle. Then when you go to full power. The engine is running faster and pumping more gallons per minute. The nozzle is too small or clogged and so the bypass opens and closes ( surges) Try a new nozzle that is the right size for your machine.
Remove the dispenser draw and pour water down the soap chute as much as you can to soften any soap causing the blockage. When the water level drops, add more water. After a while use a soft flexible rubber hose and run it down the chute up and down to remove caked soap. Once this has been achieved, run the machine on "Rinse & Spin" to clean out the drum.
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.
A "chattering" pressure washer pump can be caused by many things. You could have a bent or damaged inlet line, or the water supply might be too low. Fixing these is simple, but checking on the water supply is critical. Never let the water supply run low for any extended period of time. Other causes of a chattering pump include water that is too hot, you may have air in the pump system or a stuck float valve. A power washer pump that is vibrating, but not chattering could be the result of air in the system or debris stuck in the valves. Catching these pressure washer problems early and knowing what causes them will save you a trip to the repair shop, especially when it comes to the low-water issue.
Troubleshooting Low Nozzle Pressure
Low nozzle pressure is a common complaint generally caused by one of the following:
1. Plugged nozzle tip. 2. Inlet screen plugged. 3. Insufficient flow in gallons per minute (not pressure) to the pump. 4. Unloader valve stuck open due to debris lodged under the check valve ball. 5. Customer use of shutoff-type quick connectors. 6. Plugged hose.
Troubleshooting Pressure Washer Soap Injector
When a soap injector is not working properly, the problem is generally fairly easy to isolate. Check the following:
1. If you have interchangeable tips, make sure the Black, soap tip is installed. Soap injectors will not work when high pressure nozzles are installed. 2. Be sure that the soap injector valve is turned on, and turn selector valve to desired setting. 3. A piece of debris may be caught in the injector valve, injector ball valve, or orifice. Disassemble and clean the injector. 4. If you have an adjustable nozzle, be sure it is in the low pressure position(away from the gun) to draw soap.
Possible blockage in line or at the nozzle ends. There is a small screen that keeps debris from entering the lines but can get clogged. The screen is plastic and is inside the reservoir at the bottom between the pump and the outlet hose. Remove and clean the screen as needed. If the problem persists there is most likely a clog in the line. Slightly higher pressurized air (more than the washer pump can produce) could clear the clog. Be sure to check the nozzles for blockage too. Good luck to you
the pump gears could be stripped or clogged with soap residue including the line from the pump to include the drain hose itself. I took the back of my machine off after cleaning the pump twice to find the reservoir full of a brown soap gunk/sludge. there is also a small rubber tube that runs from this reservoir back into the drum which was plugged shut with the same gunk. this thick soap residue can damage the pump motor or slow the drainage system to get the E 04 warning. I cleaned the gray drain hose out with the garden hose and was amazed at the sludge that game out. When the machine would run on the drain cycle we would also get a sewage smell that I thought was coming form the drain trap but turned out to be caused by the sludge in the pump. After cleaning the system and now using no more that a tablespoon of soap it works great & the cloths are clean.
WE had a person with the same problem with her HE4 front loaded washer. What we discovered was when we opened up the soap resivour was that soap built up around the float valves causing them to stick.
A technician I knew put vinegar down the soap dispensor and ran the cycle, with the washer empty. He put it on in the hot water mode and ran it for four or five complete cycles like washing clothes.
It worked for him. Try it like it did for him to see if it helps. If not, you will need to contact a service technician to see if the SUD error code means something else.
Sometimes the timer boards get a bit of moisture on them and cause a corrosion headache. I have yet to see anyone figure out a way to dry them off, and when condensation builds up, it usually means there is a problem causing the condensation to get that far up. On some versions a foam seal gets worn out from time, often needs to be replaced to prevent moisture built up.
Another thing that sometimes does it is the back of the machine, will be too close to the wall or have debris back behind there causing it not to be able to breath.
