Whirlpool Washer Error Code F0 E5: Troubleshooting Guide... | appliancefaults.com

Technical Background:

The F0 E5 error code typically indicates an off-balance load detected by the machine's sensors. The MCU monitors motor speed and current draw to determine if the load is balanced. The voltage paths involved are the 5V DC reference voltage to the pressure sensor and the 120V AC voltage to the motor.

Symptoms:

The Whirlpool washer displays an F0 E5 error code, and the washer may stop mid-cycle. The load *appears* to be balanced, but the error persists. The machine may attempt to spin but then aborts.

Possible Causes:

Faulty load sensing system
Defective motor control unit (MCU)
Wiring harness issue between MCU and motor
Problem with the central control unit (CCU)
Stuck or failing pressure sensor
Damaged wire connections

Solution:

1

Unplug the washer from the outlet or turn off the breaker.
2

Inspect the wiring harness between the MCU and the motor for damage or loose connections. Repair or replace as needed.
3

Check the pressure sensor hose for kinks or blockages. Clean or replace the hose.
4

Test the voltage to the motor using a multimeter after carefully reconnecting power (120V AC). If no voltage is present, suspect the MCU.
5

Inspect the CCU for burned components or signs of water damage. Replace the CCU if damaged.
6

If the wiring, pressure sensor, and CCU appear normal, replace the MCU.
7

After repairs, run a calibration cycle on the washer. Refer to the service manual for instructions.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental energization. High voltage is present when the appliance is powered on.

Prevention:

Avoid overloading the washer. Regularly inspect the suspension rods for wear. Use the correct amount of detergent.

Expert Tip:

Enter the service mode by pressing and holding the Start/Pause button for 3 seconds, then pressing the Power button. This will allow you to run diagnostic tests and potentially clear the error code after fixing the issue. Note the error code may not clear until it is fixed!

Frequently Asked Questions

•How do I test the pressure sensor?

The pressure sensor can be tested with a multimeter. Disconnect the sensor and check the resistance between the terminals. Compare the reading to the values in the service manual. Also, check the voltage supply from the control board to the sensor, it should be around 5V DC.

•Where is the MCU located in my Whirlpool washer?

The MCU is typically located behind the lower access panel at the front of the washer or inside the control panel. Refer to your specific model's service manual for the exact location.

•What is the part number for a replacement MCU for my Whirlpool washer?

To determine the correct part number for a replacement MCU, you will need the model number of your washing machine. This can typically be found on a sticker located on the back of the machine or inside the door.
