Washer: Why is the water in my washing machine the wrong temperature?

If you get cold water when you set the washer for a hot-wash load, first make sure the water heater is doing its job. (FYI, if the water is warm instead of hot, your ENERGY STAR washer is following Department of Energy standards that limit hot water to 85-95 degrees F for the Normal cycle.)

Check to see if hot and cold water supply hoses connected to the back of the washer are reversed. Connect the supply hoses properly if you find them reversed.

If the water heater is fine, the water supply hoses are connected properly and the water comes into the washer warm when you set it for cold, then the washing machine water temperature control may not be working. Washing machines have various water temperature controls. Some washers use switches and others use electronic control boards to control water temperature. If your washer uses a temperature selector switch, the switch may need replacing. If your washer uses an electronic temperature control board or the main control board controls water temperature, then you may need to replace the control board that controls water temperature.

The washer also won't fill with the right temperature of water if the hot or cold valve on the water inlet valve assembly fails so replace the water inlet valve assembly if a valve fails.

THESE REPAIRS MAY HELP SOLVE YOUR WASHER PROBLEM

Replace the washer temperature selector switch

The temperature selector switch lets you set the temperature of the water going into the washer. The temperature selector switch switch is usually a rotary switch mounted in the control panel. If the switch fails, the washer won't fill properly or might not fill at all. If one of the water inlet fill valves isn't actuated because of defective contacts in the switch, the actual water temperature differs from the set temperature.

Replace the washer electronic temperature control board

The electronic temperature control board has a thermistor (a temperature sensor) that detects the temperature of the water entering the tub. The electronic temperature control board opens and shuts the electrically operated water inlet valves to accurately fill the washer tub with the correct temperature of fill water. If the electronic temperature control isn't controlling the fill water temperature properly, replace it.

Replace the washer water inlet valve assembly

The water inlet valve assembly is a set of water valves that control the flow of water into the washer. Replace the water valve assembly if the washer won't fill and start because a valve doesn't open, or if the washer overfills because the valve doesn't close.
