Why does H and F flash in window
Why does H and F flash on me washer machine?
Is this a good question?
F/H error code:
No water detected entering machine or Pressure switch trip not detected.
If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.
If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.
Press PAUSE/CANCEL twice to clear the display.
If there is no water in the unit:
1. Make sure that both valves at the water source(s) are turned on all the way.
2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves
3. Verify inlet valve operation
If there is water in the unit:
1. Verify Drain pump operation
2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
Verify there is not a siphon problem
Verify wire harness connections to:Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU)
Check all hoses for possible leaks
Verify pressure switch operation
Verify flow meter operation
Verify CCU operation
If this is intermittent, it would be very hard to determine the cause.
It can be caused by low water pressure into the water from the customers water supply, or clogged inlet water valve screens.
Make sure you don't have any duct tape or something around your drain pipe, it needs that air gap to prevent siphoning.
