Customers say they replaced this switch for F20, FH and HF error codes. Washers that kept filling or took on water while idle stopped doing so for several. A few tested first: if it fills while unplugged with the water on, the inlet valve is at fault; otherwise the switch. In other cases the fault was the flow sensor, inlet valve, or a chafed or clogged pressure hose.
