Resetting the washer
SOURCE: M washer keeps coming up with the f 20 error code.
F20 = NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED.
The pressure switch is not tripped after 6 minutes.
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 drain pump operation.
Verify that the pressure switch hose is in good condition and properly
connected to tub and pressure switch.
1. Verify there is not a siphon problem.
2. Press PAUSE/CANCEL twice to clear the display. The machine will drain
for 3 minutes before unlocking the door.
3. Unplug washer or disconnect power.
4. Verify wire harness connections to inlet valves, pressure switch,
drain pump and Central Control Unit (CCU).
5. Check all hoses for possible leaks.
6. Plug in washer or reconnect power
7. Verify pressure switch operation.
Hello Shirley - Typically error code ER01 indicates that a water leak is detected under the tub. Unit will possibly need a hydraulic kit. Try unplugging the unit or flipping the household circuit breaker off. Wait approximately ten minutes and turn the unit back on. Could the error code DF possibly be PF? If so, PF means power failure and you should be able to start a cycle. If the error code continues to display on dishwasher then I suggest contacting a professional to accurately diagnose and repair it.
