When I run the service test it only gets o C:00 fillswith cold then shows FH
I tested the fill switch. It is ok. The pressure tube is good. Hot and cold are fine. The pump and drain are ok. I checked the flow meter and the resistance is erratic. Is it the flow meter or what
What should it read?

Hello
The C:00 is a control action for the door lock system.
FLOW METER TEST ****
To test the flow meter disconnect the wires from it and remove the hoses so you can blow through it. Touch the terminals with an ohm meter. When you blow through it, the resistance should change. If not, it has failed.
The FH error
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 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. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves, pressure switch, drain pump, flow meter,
and Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power.
6. Verify pressure switch operation.
7. Verify flow meter operation by blowing air through the part and measuring the resistance.
8. Verify CCU operation by running a Diagnostic test or any cycle.
