The water temperature is backwards. Warm is hot, cold is hot
My washer will add hot water on cold, hot water on warm, hot water on everything. We have switched the hoses and still hot. We have turned off the hot and selected cold and the washer just hums not filling at all. We have taken to turning off our hot water tank and emptying it of hot water (showers, dish washer, etc.) in order to wash clothes on cold. It has ruined several loads of clothing with hot water!
It sounds like the wires to the hot and cold solenoids have been switched.
This isn't a solution, more a workaround. Try connecting both hoses to the cold tap. You can buy a Y-shaped adapter to fit on the tap.
If it works, think of it as an upgrade - most new washers have cold fill only.
becky hoban, the hot and cold water inlet valves are located at the back of the washer. These valves receive a control signal from the Central Control Unit to manage the temperature of incoming water. The temperatures are determined by the specific wash cycle selected and a temperature sensor located in the wash tub. Since it only hums if you select the cold, I would check the little screen filter at the water inlet first. It is possible that it is clogged and does not allow cold water to enter. If that filter (screen)is okay, check the water inlet solenoids. you will need an ohmmeter for that. You can get the service manual for your washer from here for an explanation of the testing procedure. The water valve assembly is available at places like this. Hope this helps, good luck.
