Whirlpool duet washing machine error codes – Whirlpool duet washing machine diagnostic codes explained plus recommended fixes
Below are the typical Whirlpool duet washing machine error codes, what they actually mean, and suggested repairs:
Whirlpool duet washer error code FH (F/H)
This is usually displayed when there’s no water in the machine.
Suggested fixes
- Make sure both valves -at the water source(s)- are turned on(all the way).
- Check for plugged/kinked inlet hoses as well as for plugged screens (in your inlet valves).
- Verify there’s proper inlet valve operation.
But sometimes there’s water in the washer so water supply is not the culprit.
In this case, try the following.
- Verify that the drain pump is operating properly. If not, it is the cause and a replacement might be needed.
- Verify that pressure switch hose has no problems and that it is connected properly to the tub and the pressure switch.
- Verify there’s no siphon problem.
Procedure:
- Unplug the machine / disconnect power.
- Check if the wire harness connection(s) to the inlet valves, pressure switch, drain pump, Central Control Unit(CCU), and flow meter are all fine.
- Check every hose for possible leaks.
- Plug in the washer / reconnect power
- Check if pressure switch is operating as expected.
- Check if flow meter is operating properly- to do that, simply blow air through the component and then measure the resistance.
- Verify the CCU operation by starting a Diagnostic test/any cycle and see how it goes.
