Water flowing back into washer after wash

Our Whirlpool Duet 9100 washer has an intermittant problem of water flowing back into the washer after a load is finishes and removed from the washer. We've tried emptying it by running an empty cycle and by running a drain and spin only cycle. Neither works. We've checked the position of the drain hose and it seems appropriate, the recepticle is 32" off the floor.

There is a back flow valve attached to the outlet port of the drain pump. It is just a small rubber flap. This sometimes comes loose or remains open due to debris and allows the water in the drain hose to flow back into the machine after the drain pump shuts off. It can be checked by removing the drain hose from the pump inside of the machine. You will lose all of the water in your machine (about 1/2 gallon)when you do this so be prepared with a bunch of towels.

Whirlpool duet steam washer displaying F 20 error code during wash cycle. Water seems to be flowing just fine. I've unplugged it several times to clear the code but it's not working.

The F20 error code on a Whirlpool Duet Steam Washer typically indicates a water inlet problem. It means the washer is not getting enough water to continue the wash cycle. This can be due to several reasons, even if it seems like water is flowing fine at first glance. Here are steps you can take to troubleshoot and potentially resolve the issue:
  1. Check Water Supply Hoses:
    • Ensure both the hot and cold water faucets are fully open.
    • Inspect the water inlet hoses for kinks, bends, or twists that could restrict water flow. Straighten out any issues you find.
    • Turn off the water supply, disconnect the hoses from the back of the washer, and check that the filter screens inside the water inlet valve are not clogged with debris. Clean them carefully if needed.
  2. Water Pressure:
    • The washer requires a certain amount of water pressure to function correctly. Low household water pressure can lead to insufficient water flow to the washer. Make sure your home's water pressure is within the washer's required range.
  3. Check for Siphoning:
    • Make sure the drain hose is correctly installed. The end of the hose should not be too far down the standpipe, and there should be an air gap to prevent siphoning.
  4. Inlet Valves:
    • If the water hoses and screens are clear, there might be an issue with the water inlet valves themselves. They might not be opening fully due to electrical issues or mechanical failure.
    • The inlet valves can be tested with a multimeter for continuity to ensure they are functioning correctly. If they lack continuity, they need to be replaced.
  5. Flow Meter:
    • Some Whirlpool Duet models have a flow meter that measures the amount of water entering the washer. If this component malfunctions, it could mistakenly signal that there's not enough water, even when there is.
    • Diagnosing a flow meter requires some technical knowledge and a service manual for your specific model.
  6. Pressure Switch:
    • The washer uses a pressure switch to monitor the water level. If there's an issue with this switch or the hose connected to it, the washer might incorrectly interpret the problem as insufficient water flow.
    • Check the pressure switch and the hose for any blockage, disconnection, or damage.
  7. Reset the Washer:
    • Since unplugging the washer hasn't cleared the error, after checking the above, try to reset the control board by unplugging the washer for about 5 minutes, then plugging it back in.
If after trying these steps the F20 error persists, it may be time to consult the manual for more specific troubleshooting steps for your model or contact a professional appliance repair service. Sometimes, the problem could be related to the washer's electronic control board or other components that require professional diagnosis and repair.

Code f 20 what does that mean and how can I fix it.

A possible solution to an f 20 fill error for a whirlpool duet washing machine. Blow out the pressure hose that connects to the pressure switch.

Before doing any of these fixes first ask yourself if you have over loaded the machine. Too many Bulky - heavy items will cause this same message.
How to fix Whirlpool Duet F20 Error:
Whirlpool uses a flow meter that detects the flow of water entering the washer. If this flow meter does not detect the correct amount of water entering the washer it will sound the F20 error code. Often this repair can be made with out calling an appliance repairman and without ordering parts. Start by removing the washer fill hoses; both the cold and the hot water hoses. Check for proper water pressure from the house. To do so, turn the water on and put the hose inside the washer or a bucket.
If water pressure is good, check the water valve inlet screens. Most residential washing machines have inlet screens. The screens prevent minerals from clogging the solenoid. With the hoses removed, you can visually inspect the water inlet screens. If the water valve screens are clear the inlet valve with the screens itself will need to be replaced. To replace the water valve, remove the top of the washing machine. Three screws hold the top down. The screws that hold the top down are on the back of the top panel. Once removed the top will slide back and off. Now remove the wire harness that connects to the valve. One screw holds the valve to the washers cabinet. Removing the screw and sliding the valve over will release the valve from the back panel enabling you to complete your repair.
One last thing to check is the fill hoses. These front load duet washers call for a lot of water quickly. So if you have stainless steel braided flood-safe hoses, they will trip for no reason at all. Replace these flood safe hoses with more traditional hoses.

Whirlpool Duet 9100 will not drain during regular wash cycle. Cleaned drain filter & ran diagnostic and then rinse & drain. Water drained from washer & clothes were damp and I thought the...

I would assume that you are using HE detergent if not the pump could go into a suds lock. You may have a bad drain pump. The other options could be possibly a bad central control unit. (however these are very expensive) or possibly a door lock issue but usually you will get a door lock error.

Whirlpool Duet 9100 starts cycle then stops & wont drain

F2 code is a drain issue. If you are not using he detergent you can cause slow draining and then you will get the code. Try using less detergent. Also, try disconnecting the power to the washer to reset controls.
