Maytag Washing Machine Error Code F0E4: High Water... | appliancefaults.com

Technical Background:

The Central Control Unit (CCU) monitors the water temperature sensor (thermistor) to ensure the water temperature is within the programmed limits. When the CCU detects a temperature exceeding a set threshold for a prolonged period, it triggers the F0E4 error. The thermistor changes its resistance based on water temperature; the CCU reads this resistance via a 5V DC circuit.

Symptoms:

The homeowner observes that the washing machine displays error code F0E4. The washer may also fill with hot water even when set to a cold water cycle. Clothes may feel excessively hot after washing.

Possible Causes:

Faulty water temperature sensor (thermistor).
Defective water inlet valve(s) allowing hot water to leak in.
Malfunctioning Central Control Unit (CCU).
Wiring harness issue between the thermistor and CCU.
Grounded heating element (if equipped on specific models).
Drain pump running continuously causing water heating.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the water temperature sensor (thermistor). It's usually near the water inlet valve or in the tub. Access it by removing the top or rear panel using a 1/4-inch nut driver.
3

Disconnect the thermistor and measure its resistance using a multimeter. Refer to the service manual for the correct resistance value at room temperature (typically around 77°F). A typical reading might be 10,000 ohms at 77°F. Replace if the reading is significantly different.
4

Inspect the wiring harness and connectors between the thermistor and the CCU for any damage or loose connections. Repair or replace as needed. Use wire strippers and crimpers if needed.
5

Check the water inlet valves for leakage. Turn off the water supply and disconnect the hoses. Inspect the valve seats for debris or damage. Replace if necessary. Use pliers to disconnect hoses.
6

If the thermistor and wiring are good, and the inlet valves are not leaking, suspect a faulty CCU. Replace the CCU as a last resort. Note: CCU replacement may require programming with a service dongle.
7

After repairs, reconnect power and run a test cycle to verify the F0E4 error is resolved.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lock-out/Tag-out (LOTO) procedures should be followed. High voltage is present when the appliance is powered on.

Prevention:

Periodically check the water inlet hoses for leaks and replace them every 5 years. Clean the water inlet valve screens to prevent debris buildup. Avoid overloading the washing machine.

Expert Tip:

Many Maytag washers have a diagnostic mode. To enter, press and hold the Start/Pause button for 3 seconds, then quickly press and release the following buttons in sequence: Rinse, Spin, Wash, Rinse. This will allow you to view error codes and run diagnostic tests.

Frequently Asked Questions

•Where is the water temperature sensor (thermistor) located on my specific Maytag washer model?

The thermistor's location varies. Consult your washer's service manual or look for it near the water inlet valve or embedded in the outer tub housing. Common locations are accessible after removing the top or rear panel.

•How do I test the water inlet valves for leakage?

Turn off the water supply to the washer. Disconnect the inlet hoses from the valves. Place a bucket under the valves and turn the water supply back on briefly. If water drips from the valves when they are supposed to be closed, they are leaking and need replacement.

•What is the correct resistance value for the thermistor at different temperatures?

The resistance of the thermistor varies inversely with temperature. Refer to the service manual for a resistance chart specific to your model. A typical thermistor might read 10,000 ohms at 77°F and 3,000 ohms at 140°F.
