Our washer does not know warm. Have it run hot, and it is HOT. Have it on cold and it is COLD. Have it on warm and it is HOT.
When under warranty, a guy replaced the water temp switch. It seemed to help some, but it still was not quite right.
I can use a multi-meter. I have a diagram. I have torn the thing apart and know how to get at everything. But, I am not certain what I am looking for or what to test. I am guessing the the water valve is messed up, or a thermostat. I see on the diagram a temp control light, but I have NO idea where that light might be.
Can you help get me started?
