When your Maytag washer water is the wrong temperature, the temperature sensor is the most likely cause. This sensor monitors tub temperature and signals the water inlet valve to release more hot or cold water. Test it with a multimeter for proper electrical continuity and replace it if it fails. A faulty temperature selector switch can also send incorrect power to the water inlet valve, causing a washer with no hot water, water that is too cold, or water that is too hot. The dispenser door is another highly likely cause listed for this symptom and should be inspected for damage or improper operation. Next, check for clogged screens in the fill hoses or water inlet valve. Unplug the washer, shut off both water supplies, remove the hoses, and clean away any debris from the screens. Reversed fill hoses can make wash and rinse temperatures seem wrong, so confirm the hot and cold connections match the markings on the valve. If these checks do not solve the problem, test the temperature control switch, which powers the valve's hot and cold solenoids.

01 - Maytag 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.

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.

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.

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.

06 - Maytag 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.
