GE Washer Error Code 31: Water Level Pressure Sensor... | appliancefaults.com

Technical Background:

The washer's main control board (MCU) uses the water level pressure sensor to determine the water level inside the tub. The sensor converts water pressure into an electrical signal (voltage), which is sent to the MCU. The MCU uses this signal to control the water inlet valve and prevent overfilling. error code 31 indicates the MCU is not receiving a valid signal from the sensor or detects an out-of-range value. This can be due to wiring, sensor or hose faults.

Symptoms:

The GE washer displays error code 31. The washer may not fill properly, overfill, or not start the wash cycle. The control panel may be unresponsive or indicate an incorrect water level.

Possible Causes:

Faulty water level pressure sensor
Obstruction in the pressure hose
Loose wiring connections to the sensor or control board
Defective main control board (MCU)
Air leak in the pressure sensing system
Voltage supply problem to the water level sensor

Solution:

1

Unplug the washer from the 120V AC outlet or turn off the breaker to the washer circuit in the breaker panel.
2

Locate the water level pressure sensor, usually at the bottom of the washer near the pump or attached to the frame. Remove the front panel with a 1/4-inch nut driver.
3

Disconnect the pressure hose from the sensor and inspect for kinks, cracks, or obstructions. Clear any blockages with a small wire or compressed air.
4

Check the wiring connections to the sensor and the main control board. Ensure they are secure and free from corrosion. Repair or replace any damaged wiring.
5

Use a multimeter to test the sensor's voltage. With the washer powered on (carefully, while plugged in), a good sensor will typically show a fluctuating DC voltage between 0.5V and 5V depending on the water level. Refer to the service manual for specific voltage ranges.
6

If the sensor tests bad, replace it with a new one. GE part number verification is essential.
7

Reconnect all components, plug the washer back in, and run a test cycle to see if the error code clears. If the error persists, the MCU might need replacement.

Safety Warning:

Disconnect power to the washer before performing any repairs. High voltage is present inside the washer. Lock-Out/Tag-Out (LOTO) procedures should be followed to prevent accidental energization.

Prevention:

Periodically inspect the pressure hose for kinks or damage. Use a washing machine cleaner regularly to prevent buildup that can obstruct the hose. Ensure the washer is level to prevent water level errors.

Expert Tip:

Some GE washers have a service mode that allows you to test the water level sensor. Typically, you can access the service mode by pressing and holding specific button combinations on the control panel. Consult the service manual for the exact sequence for your model. This can help isolate the issue.

Frequently Asked Questions

•Where is the water level pressure sensor located on my GE washer model?

The water level pressure sensor is typically located at the bottom of the washer cabinet, either near the pump or mounted on the frame. Refer to the service manual for your specific model for the exact location.

•What is the correct voltage range for the water level pressure sensor on my GE washer?

The voltage range for a functioning sensor generally fluctuates between 0.5V and 5V DC, depending on water level. Specific values can be found in the washer's service manual. Different models may have slightly varying voltage ranges.

•How do I access the service mode on my GE washer to test the water level sensor?

The service mode access varies depending on the GE washer model. Consult the service manual for specific button combinations (e.g., pressing and holding Start and Pause simultaneously) to initiate the service mode. Once in service mode, there should be diagnostic tests for the water level sensor.
