Hello
The F20 Error code is : (NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED) If, after 30 seconds during Diagnostic Test, less than 3.3 oz (0.1 L) of water has entered the machine, or if
during a cycle, the maximum fill time of 13 minutes is exceeded, the valves will be turned off and the error
code will be displayed. Press PAUSE/CANCEL twice to clear the display.

Possible Causes/Procedure
* If there is no water in the unit:
– Make sure that both valves at the water source(s)
are turned on all the way.
– Check for plugged or kinked inlet hoses
or plugged screens in the inlet valves.
– Verify inlet valve operation.
* If there is water in the unit:
– Verify that the pressure switch hose is in good
condition and properly connected to tub and
pressure switch.
1. Unplug washer or disconnect power.
2. Verify there is not a siphon problem.
3. Verify wire harness connections to inlet valves,
pressure switch, and Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power.
6. Verify pressure switch operation (run diagnostic test).
7. Verify CCU operation by running a Diagnostic Test cycle
