I know what the C:00 means I was just describing what happens in the service mode. I have done all these tests but need some expertise on any specific reading on the flow meter ohms. It does change when water fills it but is it normal for the reading to be eratic? Could it be the CCU?
When I run the service test it only gets o C:00 fillswith cold then shows FH
Model Number
Mfw9600sq0
What have you tried so far?
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
If the flow meter has 5 volts DC and you get erratic resistance when blowing through the tube the flow meter, the meter is operating normal and is not your issue. The flow meter resistance will change based on pressure. There are two other possibilities that will cause your FH error.
1) Remove the pressure hose WPW10004260 , inspect it carefully to make sur there is not a pin hole leak in it. We have found this to cause your FH error many times. You cannot phisically see it sometimes but if you have a pinhole leak the pressure switch will not operate.
2) Make sure you do not have flood safe water inlet hoses with check valves in them. These can cause FH error codes also.
Please let me know if either of these suggestions correct your issue.
