Admiral Washer Error Code 130: Rotor Position Sensor... | appliancefaults.com

Technical Background:

The rotor position sensor provides feedback to the MCU about the rotor's position and speed. The MCU uses this information to control the motor's operation. Error 130 indicates that the MCU is not receiving a valid signal from the sensor, disrupting the washing cycle. The sensor typically operates on a 5V DC circuit, and variations in resistance signal rotor position. Incorrect voltage or resistance values trigger the error.

Symptoms:

The Admiral washer displays error code 130 and may not start, or it may start and then stop mid-cycle. The motor may not spin, or it may spin erratically. There might be unusual noises coming from the motor area.

Possible Causes:

Faulty rotor position sensor
Wiring harness damage to the sensor
Loose connection at the motor control unit (MCU)
Defective MCU
Motor malfunction causing erratic rotor behavior
Obstruction preventing rotor movement.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the rotor position sensor, typically near the motor.
3

Inspect the wiring harness for any visible damage, cuts, or abrasions. Repair or replace the harness as needed.
4

Check the sensor connector at the MCU for proper seating and corrosion. Clean with electrical contact cleaner if needed.
5

Use a multimeter to test the sensor's resistance. Refer to the service manual for the correct resistance range. Replace the sensor if it's out of spec.
6

Inspect the motor for any obstructions preventing rotor movement. Remove any foreign objects.
7

If the wiring and sensor test okay, the MCU may be defective and require replacement. Verify all other components before replacing the MCU.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental power-up. High voltage components are present; exercise caution.

Prevention:

Periodically inspect the wiring harness for signs of wear and tear. Avoid overloading the washer, which can strain the motor and sensor. Ensure the washer is level to prevent excessive vibration.

Expert Tip:

Some Admiral washers have a diagnostic mode. To enter the service mode, simultaneously press and hold the Start/Pause and Cycle Select buttons for 3 seconds. This may provide more specific error codes or sensor readings.

Frequently Asked Questions

•What is the typical resistance range for the rotor position sensor on this Admiral washer?

The typical resistance range for the rotor position sensor varies by model, but it's often between 500 and 1500 ohms. Consult the specific service manual for your Admiral washer model.

•Where is the MCU located in this Admiral washer model?

The MCU is typically located behind the control panel or near the motor. Refer to the wiring diagram and service manual for your specific Admiral washer model to pinpoint its exact location.

•Can a faulty motor cause a false error code 130?

Yes, a faulty motor can indeed cause a false error code 130. If the motor's bearings are worn, or if the motor is drawing excessive current, it can affect the rotor's position and speed, leading to an inaccurate signal from the sensor and triggering the error code.
