Hello Everyone,

I have a Whirlpool WFW9250WW00 washer that will not work with hot or warm water. If I attempt to do a load with hot/warm no water enters the washer and I eventually get a LF error. The washer works fine with cold water.

I have so far replaced the hot water inlet valve and the pressure switch. I am also sure that I am getting plenty of hot water to the valve. I still have the same problem.

I tested the continuity of the wire going from the computer to the water inlet valve and the wire is good.

I don't want to just keep throwing parts at this thing.

Is there a way that I can do some tests or something so that I can figure out what is wrong? Any advise would be most appreciated.

Hello Simon,

I located the VCH7 plug.

I checked the resistance on the plug between 5-7 pins and got a reading of 800 ohms. So, according to your instructions I should replace the CCU.

However, I am confused because I also checked the resistance on the computer and got a reading of zero ohms.

Maybe I am not thinking about this correctly but it seems to me that I should be checking the resistance on the CCU if I am trying to determine if the CCU has a problem.

In addition, it seems to me that the D16 plug on the CCU controls the hot water inlet valve. Should I be checking the computer and or plug at D16?

The wire going from the valve to the D16 plug is showing zero resistance, so it is good.

I sincerely appreciate the help but I do not want to order a $160.00 part unless I am sure it is what I need.

Thanks,

Chad
