GE Washer Error Code 45: Water Level Sensor... | appliancefaults.com

Technical Background:

The GE washer's main control unit (MCU) uses the water level pressure sensor (transducer) to monitor the water level in the tub. The sensor converts pressure changes into an electrical signal, which is sent to the MCU. The MCU uses this signal to control the fill valve and prevent overfilling or running dry. error code 45 indicates that the MCU is receiving a signal from the sensor that is outside of the expected range.

Symptoms:

The homeowner observes that the washer displays an error code 45. The washer may not fill properly, overfill, or stop mid-cycle.

Possible Causes:

Faulty water level pressure sensor (transducer).
Obstruction in the pressure hose.
Loose or corroded wiring connections to the sensor.
Defective main control board (MCU).
Air leak in the air dome or hose connection.
Excessive suds interfering with the sensor reading.

Solution:

1

Disconnect power to the washer at the breaker panel. Verify 0V AC at the wall outlet using a multimeter.
2

Locate the water level pressure sensor. It's usually near the bottom of the washer, connected to a small hose.
3

Inspect the hose for kinks, clogs, or damage. Disconnect the hose from both the sensor and the tub, and blow through it to check for obstructions. Clean if necessary.
4

Check the wiring connections to the pressure sensor. Look for loose connections, corrosion, or damage. Use a wire brush to clean any corroded terminals. Reconnect securely.
5

Use a multimeter to test the sensor's resistance. Consult the washer's service manual for the correct resistance range. If the sensor's resistance is out of range, replace it.
6

If the sensor and wiring appear to be good, the main control board (MCU) may be faulty. Replacing the MCU is a more complex repair best left to a qualified technician.
7

After making any repairs, reconnect power to the washer and run a test cycle to verify that the error code 45 is resolved.

Safety Warning:

Always disconnect power to the washer before performing any repairs. Lock Out, Tag Out (LOTO) procedures must be followed. Some components may retain high voltage even after the power is disconnected.

Prevention:

Periodically check the pressure hose for kinks or obstructions. Use the correct amount of detergent to prevent excessive suds.

Expert Tip:

Many GE washers have a diagnostic mode. Consult the service manual to learn how to enter the diagnostic mode and retrieve specific error codes and sensor readings. Use a 1/4-inch nut driver to remove the front panel.

Frequently Asked Questions

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

The water level sensor is usually located at the bottom of the washer cabinet, typically on the left or right side. It's connected to the tub with a small rubber hose. Refer to your washer's service manual for the exact location.

•What is the proper resistance reading for the water level sensor on my GE washer?

The resistance reading varies depending on the model. Consult the service manual for your specific washer model. The manual will provide a range of acceptable resistance values.

•How do I access the diagnostic mode on my GE washer to read the water level sensor data?

The procedure for entering diagnostic mode varies depending on the model. Typically, it involves pressing a specific sequence of buttons on the control panel. Consult your washer's service manual for the exact steps.
