Washer water is the wrong temperature
If your washer water is the wrong temperature, the washer may be using too much hot or cold water, or the water supply may be reversed. The most likely cause is a faulty temperature sensor, which tells the water inlet valve when to release hot or cold water. A defective temperature selector switch can also send the wrong signal, causing a washer with no hot water or water that is too cold or too hot. Next, inspect the dispenser door, since a damaged door can interfere with proper temperature selection. Clogged screens in the fill hoses or water inlet valve can restrict hot or cold water flow, so unplug the machine, shut off the water, and clean the screens. Also check that the hot and cold fill hoses are connected to the correct ports. Less commonly, the temperature control switch may not send the proper voltage to the water inlet valve solenoids. Test these parts with a multimeter when appropriate, and replace any defective component. Enter your model number to find the exact replacement temperature sensor, switch, water inlet valve, or dispenser door for your specific washing machine.
01 - Washing Machine Temperature Sensor
The washer's temperature sensor determines whether more hot or cold water should be released by the water inlet valve to maintain an appropriate water temperature in the tub. If the sensor is faulty, the incoming water may be the wrong temperature. You can use a multimeter to test the sensor for appropriate electrical continuity. If the sensor tests inappropriately, the part will need to be replaced.

Highly Likely
02 - Washing Machine Temperature Switch
The temperature selector switch allows power to be sent to the water inlet valve to release hot or cold water. If the temperature selector switch is faulty, the valve may only allow only one temperature of water to fill the tub. You can use a multimeter to test the switch for electrical continuity. If the switch tests negative for continuity, the part will need to be replaced.
Highly Likely
03 - Washing Machine Dispenser Door
The temperature selector switch allows power to be sent to the water inlet valve to release hot or cold water. If the temperature selector switch is faulty, the valve may only allow only one temperature of water to fill the tub. You can use a multimeter to test the switch for electrical continuity. If the switch tests negative for continuity, the part will need to be replaced.
Highly Likely
04 - Clogged Screens in Fill Hose or Water Inlet Valve
All water valves have filter screens to prevent particles from clogging the valve or stop the valve from closing. For added protection and easier access, some fill hoses may have screens added to the hose washers/gaskets where the fill hose connects to the homes hot or cold shut-off valve. The screens in the water valve and hoses should be checked and cleaned if necessary. Unplug the machine. Turn off the water supply valves. Get a bucket to catch the remaining water in the hoses. Unthread the hoses from your machine and clean any debris from the filter screens.
Common
05 - Fill hoses reversed
If the fill hoses are not connected to the appropriate valve faucets or ports (one hose connecting the cold water supply valve to the washer's cold water inlet valve port and the other hose connecting the hot water supply valve to the hot water inlet valve port), the wash and rinse water temperatures will be reversed. Check that the fill hoses are connected correctly. There are usually markings next to the water inlet valve connections for the hot (H) and cold (C) designations.
Common
06 - Washing Machine Temperature Control Switch
The temperature control switch switches power to either the cold or hot solenoid on the water supply valve to maintain the proper water temperature. If the temperature control switch is defective the water inlet valve may not receive the proper voltage to work properly. If the temperature control switch is not sending proper voltage to the water inlet valve solenoids it will need to be replaced.
Less Common
07 - Washing Machine Water Inlet Valve
A defective water inlet valve may only be allowing one temperature of water to fill the tub. In addition, some water inlet valves will have a temperature sensor built in to determine whether more hot or cold water should be released to maintain an appropriate water temperature in the tub. If the valve's sensor is faulty, the incoming water may be the wrong temperature. In either case, a defective inlet valve should be replaced with a new one.
