Kitchenaid Washer Error Code FH

Error code FH on your KitchenAid washer indicates a failure to detect water entering the machine or a lack of pressure switch trip. This can lead to issues with the proper functioning of your washer. The error is designed to safeguard the appliance and its components from potential damage due to insufficient water supply.

Troubleshooting Steps:

1. Check Water Supply:

   Ensure that the water supply valves are fully open. If there’s no water in the unit, it might be due to closed valves.

2. Inspect Inlet Hoses:

   Check for any kinks or blockages in the inlet hoses leading to the washer. Make sure they are not twisted or bent.

3. Examine Inlet Valve Screens:

   Inspect the screens in the inlet valves for any debris or blockages. Clean or replace the screens if necessary.

4. Verify Inlet Valve Operation:

   Confirm that the inlet valve is functioning correctly. If it’s malfunctioning, it may not allow water into the machine.

5. Check Drain Pump and Pressure Switch Hose:

   Verify that the drain pump is operational and not causing any water drainage issues. Examine the pressure switch hose for damage or disconnection. Ensure it’s securely connected.

6. Inspect for Siphon Problems:

   Check for siphoning issues, where water is draining out of the machine too quickly. Adjust the drain hose to prevent siphoning.

7. Look for Hose Leaks:

   Inspect all hoses for possible leaks. Leaks can contribute to insufficient water levels in the machine.

8. Check Wire Harness Connections:

   Unplug the washer and disconnect the power. Inspect and secure all wire harness connections to the inlet valve, pressure switch, drain pump, flow meter, and Central Control Unit (CCU).

9. Verify Pressure Switch and Flow Meter:

   Reconnect the unit and power. Check that the pressure switch is operational. Test the flow meter by blowing air through it and measure the resistance.

10. Confirm CCU Operation:

    Check the Central Control Unit (CCU) by performing a diagnostic test or running any cycle.

11. Replace Failed Component:

    If all else fails, and the issue persists, it may be necessary to replace the component that has failed, whether it’s the inlet valve, pressure switch, drain pump, flow meter, or CCU.

Remember, if you’re unsure or uncomfortable performing these checks yourself, it’s always recommended to seek the assistance of a professional technician
