GE Profile Washer Error Code E3: Motor Hall Sensor... | appliancefaults.com

Technical Background:

The MCU (Microcontroller Unit) on the main control board uses the motor hall sensor signal to detect motor speed and position. The hall sensor generates a pulsed DC voltage signal proportional to the motor's rotation. The MCU interprets these pulses to ensure proper motor function. If the signal is missing, inconsistent, or out of range, the MCU triggers the E3 error to prevent damage.

Symptoms:

The washer displays an E3 error code on the control panel. The washer may fail to start or may stop mid-cycle. The motor may not spin or may spin erratically.

Possible Causes:

Faulty motor hall sensor
Wiring harness issue between the motor and the control board
Loose connection at the motor or control board
Damaged motor control board
Obstruction preventing motor rotation
Motor failure

Solution:

1

Disconnect power to the washer at the breaker panel (LOTO).
2

Access the motor and motor control board area. Typically involves removing the rear panel using a 1/4-inch nut driver.
3

Locate the motor hall sensor connector on the motor. Visually inspect the connector and wiring for damage or corrosion.
4

Use a multimeter to check the hall sensor wiring harness for continuity between the motor connector and the control board connector. Refer to the wiring diagram for the specific wire colors.
5

With the washer powered on (carefully, following safety precautions), backprobe the hall sensor wires with your multimeter (DC voltage setting). You should see a fluctuating voltage (typically around 5V DC) as you manually rotate the motor pulley. No voltage or a constant voltage indicates a sensor problem.
6

If the wiring and sensor appear to be functional, but the E3 error persists, the motor control board may be defective. Replacement of the board might be required.
7

Reassemble the washer, ensuring all connections are secure. Restore power at the breaker panel.

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage is present within the appliance and can cause serious injury or death. Use proper Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Periodically inspect the wiring harness for any signs of wear or damage. Ensure the washer is not overloaded. Avoid using excessive amounts of detergent, which can cause buildup and strain on the motor.

Expert Tip:

Many GE washers have a diagnostic mode. Refer to the service manual for your specific model to enter the diagnostic mode and retrieve detailed error information. This can help pinpoint the source of the E3 error more accurately. The specific sequence varies by model but often involves pressing and holding specific buttons in a particular order. Consult the service manual.

Frequently Asked Questions

•How do I locate the motor hall sensor on my GE Profile washer?

The hall sensor is typically located on the motor housing, near the motor pulley. It's a small, rectangular sensor with a wiring harness connected to it. Refer to the service manual for a specific diagram.

•What is the correct resistance value for the motor hall sensor wiring?

The resistance should be very low, close to 0 ohms, indicating a good connection. High resistance indicates a break or corrosion in the wiring.

•Where can I find the wiring diagram for my GE Profile washer model?

Wiring diagrams are often included in the service manual. You can usually find a copy online by searching for your model number and 'service manual'. They may also be attached to the inside of the washer cabinet.
