How to Fix Whirlpool Washer F20 Error Code

If your Whirlpool washer is displaying the F20 error code, it means the machine is not getting enough water to fill the drum and complete a wash cycle. This issue is typically caused by the water supply being turned off, but it can also result from blocked or kinked inlet hoses, a clogged water inlet valve, or a faulty pressure switch.

1. Check the Water Supply

First, ensure that both the hot and cold water faucets are turned on completely. If the faucets are open but the washer still isn't receiving water, check whether there is a general water supply issue in your home. Low water pressure can also trigger the F20 error.

2. Inspect the Inlet Hoses

Blocked or kinked inlet hoses can prevent water from reaching the washer. Check the hoses for bends or obstructions and straighten or clean them as needed.

3. Clean the Water Inlet Screens

The washer’s water inlet valves have small screens that filter out debris. Over time, these screens can become clogged, reducing water flow. To clean them:

• Turn off the water supply.
• Disconnect the hot and cold hoses.
• Remove any debris from the screens.
• Reconnect the hoses and test the washer.

4. Reset the Control Board

Sometimes, the F20 error is caused by a control board glitch. You can try clearing the error code by:

• Pressing Pause/Cancel twice.
• Performing a hard reset by unplugging the washer for a few minutes before reconnecting it.

If the error code persists, continue troubleshooting.

5. Test the Pressure Switch

The pressure switch regulates water levels in the drum. If it malfunctions, the washer may not recognize that it is filling correctly. To check it:

• Locate the pressure switch (usually at the top of the washer).
• Disconnect the attached hose and inspect it for blockages.
• Use a multimeter to test the switch for continuity.

If the pressure switch is defective, it will need to be replaced. Make sure to use the correct replacement part for your washer model.
