John G. for Model Number WFW9200SQA12 We are getting an f20 error code. We have cleaned out the bottom valve and whenever we have a heavy load we get this error code. Otherwise, it runs fine. Any suggestions on what part we should repair?
Answer Hello John, As per the tech sheet: 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 the tub and pressure switch. 1. Unplug the 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 the washer or reconnect power. 6. Verify pressure switch operation (run diagnostic test). 7. Verify CCU operation by running a Diagnostic Test or any cycle. Details on the diagnostic test are included on the tech sheet found on the unit. This is normally located behind the lower kickplate of the machine in a plastic bag. Read More...
