Clearing F20 Error Code
To remove the F20 error code from your washer’s display, you have a few methods to try:
Method 1: Using Pause and Cancel
Press the Pause and Cancel buttons twice on the display panel. This often clears the error code, at least temporarily.
Method 2: Power Reset
If pressing Pause and Cancel doesn’t resolve the issue, proceed with a power reset:
- Unplug the washer from its power source for 2 minutes.
- Plug it back in.
- Choose a wash cycle and press the Start button.
It’s worth noting that when you start the washer for the first time after disconnecting it from power, it might initiate a draining cycle. During this 8 to 10-minute draining period, you won’t be able to use the pause or cancel functions. If the F20 or FH error code reappears, further diagnosis is required.
Verifying Water Valve Positions
Make sure both HOT and COLD water valves are fully open. Your washer’s water inlet valve needs pressure from both hot and cold water lines to function correctly. If only one hose is connected, the washer will not operate as it should.

Examining Water Hoses/Inlet Screens
Hose Condition
Ensure that the water supply hoses connected to your washer are not bent or kinked. A bent hose could restrict water flow, contributing to error codes and other operational issues.
Inlet Valve Filter Screen Check
To inspect the filter screens on the water inlet valve, follow these steps:
- Turn off the water supply at the valves.
- Disconnect the water hoses from the inlet valves located at the back of the washer.
- Locate the filter screens and remove any debris that might be obstructing them.
- Reconnect the hoses.
- Turn the water supply back on.
- Check for any leaks to ensure a secure connection.

Detergent and Water Supply
Using the Right Detergent
It’s crucial to use High Efficiency (HE) detergent in your washer. Always check for the HE logo on the detergent packaging before making a purchase. Using non-HE detergent can lead to excessive suds, which can interfere with the washer’s ability to detect incoming water. Remember that concentrated HE detergents require a smaller quantity.

Use Flood Preventing Hoses
These specialized hoses contain an internal check valve that triggers when water pressure exceeds 2 gallons per 60 seconds. If activated, the valve will halt water flow to the washer. This feature also comes into play if a hose becomes loose, increasing water flow and thereby closing the valve to prevent potential leaks.
Monitoring Water Pressure
Your washer needs a minimum water pressure to function correctly. If the water pressure is less than 11 psi, you’ll encounter operational issues. To ascertain your water pressure level, consult your local water company.

Hello,
We keep getting the F20 error code. We unplugged it and turned back on it did not work. Sometimes it worked with the quick wash cycle. But the regular cycle never works. Kept receiving the flashing F20 Error.
Any idea how to fix it?
Thanks,
I have a whirlpool duet front loader. Everything is cleared, cleaned, replaced, pressured, etc.
F-20 at the start of the softener cycle. 1 in 5 loads works. The clean cycle doesn’t work either. Takes in my cleaner or bleach, spins around for 45 seconds then drains out of the cleaner. Then runs with plain water or no water at all. About 15 minutes into the cycle it will F-20. Repair guy was stumped. Time for a new mother board or different brand
I have to report that replacing the inlet valve (replaced the hoses too, as they were old) fixed the F20. Note: The screens on the valve looked clean, still something was wrong inside.
Washer works in normal and heavy duty … did five loads without the error.
