Kenmore Washer F20 Water Supply Problem

What Does the F20 Error Mean?

The Kenmore washer F20 error code indicates that the washer is not receiving an adequate water supply during the fill cycle.

The control board monitors how quickly the washer fills with water. If the required water level is not reached within a specified time, the washer may stop the cycle and display the F20 error code.


Common Causes of the Kenmore F20 Error

Several issues can trigger the F20 error code, including:

  • Water supply valves turned off
  • Low household water pressure
  • Kinked or blocked inlet hoses
  • Clogged inlet filter screens
  • Faulty water inlet valve
  • Frozen water lines
  • Pressure sensor issues
  • Control board problems

How To Fix Kenmore Washer F20 Error

Follow these troubleshooting steps to help diagnose and fix the F20 error code.

1. Check the Water Supply Valves

Verify that both hot and cold water valves are fully open.

Many Kenmore washers require both water supplies to operate properly.

2. Inspect the Water Inlet Hoses

Check the hoses behind the washer for:

  • kinks
  • bends
  • blockages
  • leaks

Replace damaged hoses if necessary.

3. Clean the Inlet Filter Screens

Turn off the water supply and disconnect the hoses.

Inspect the inlet screens for:

  • sediment
  • mineral buildup
  • debris

Clean the screens carefully before reconnecting the hoses.

4. Verify Water Pressure

Low water pressure can prevent the washer from filling correctly.

Check nearby faucets to confirm adequate water flow.

5. Inspect the Water Inlet Valve

If water flow remains weak or inconsistent, the inlet valve may be defective and require replacement.

6. Run a Test Cycle

Reconnect power and start a short wash cycle to determine whether the error returns.


How To Reset Kenmore Washer After F20 Error

You can often reset the washer using these steps:

  1. Turn off the washer.
  2. Unplug the washer from power.
  3. Wait approximately 5 minutes.
  4. Plug the washer back in.
  5. Start a new wash cycle.

Some Kenmore washer models may use slightly different reset procedures.
