Admiral Washer Error Code Err 10: Heater Temperature... | appliancefaults.com

Technical Background:

The main control unit (MCU) monitors the water temperature via the heater temperature sensor. The sensor provides a resistance value proportional to the water temperature. The MCU interprets this resistance to control the heating element. Err 10 indicates that the MCU is receiving an unexpected or out-of-range signal from the sensor.

Symptoms:

The Admiral washer displays error code Err 10. The washer may not heat the water properly, or the cycle may stop prematurely.

Possible Causes:

Faulty heater temperature sensor
Wiring harness issue between sensor and control board
Loose connection at the sensor or control board
Defective main control board (MCU)
Heater element malfunction causing erratic sensor readings
Mineral buildup on the sensor affecting accuracy

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the heater temperature sensor, typically near the heating element at the bottom of the wash tub.
3

Inspect the wiring harness and connections to the sensor for damage or corrosion. Repair or replace as needed.
4

Using a multimeter, measure the resistance of the temperature sensor. Consult the service manual for the expected value at room temperature (typically around 77°F).
5

If the sensor resistance is outside the specified range, replace the sensor with a new one.
6

Check the voltage at the sensor connector on the main control board (MCU). You should typically see a low DC voltage (around 5V DC) from the MCU.
7

If the voltage is incorrect or absent, the main control board may be defective and require replacement.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Capacitors in the control board can retain a dangerous electrical charge even after the power is disconnected. Lock-out/Tag-out (LOTO) procedures must be followed.

Prevention:

Periodically inspect the water inlet hoses for leaks and mineral buildup. Use a washing machine cleaner regularly to prevent scale buildup on the heating element and sensor.

Expert Tip:

Some Admiral washers have a diagnostic mode. To access, press and hold the Start/Pause button and simultaneously press the Power button. The error codes are then displayed on the control panel. Refer to the service manual for details on accessing the diagnostic mode and interpreting the codes.

Frequently Asked Questions

•What is the typical resistance range for the heater temperature sensor at room temperature (77°F)?

The resistance range for the heater temperature sensor at 77°F is typically between 10k ohms and 20k ohms. Refer to the service manual for your specific model for precise values.

•How do I access the diagnostic mode on my Admiral washer?

Accessing the diagnostic mode varies depending on the model. Usually, it involves a sequence of button presses while the washer is powered off. A common method is to press and hold the Start/Pause button while pressing the Power button. Consult your washer's service manual for the correct procedure.

•Where is the main control board (MCU) located in the Admiral washer?

The main control board (MCU) is typically located behind the control panel on the top of the washer or sometimes at the rear of the machine, behind an access panel. You'll need to remove screws or clips to access it. Always disconnect power before accessing the MCU.
