GE Washer Error Code E22: Dual Water Inlet Valve... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) controls the water inlet valve by sending 120V AC to energize the hot and cold water solenoids. The MCU monitors the water level using a pressure sensor. If the expected water level is not reached within a specific timeframe, or if the valve fails to open, the E22 error is triggered. The valve has two separate coils, one for hot and one for cold.

Symptoms:

The washer is displaying an E22 error code. The washer might not be filling with water, or it may be filling very slowly. The water may also be cold when hot water is selected.

Possible Causes:

Faulty dual water inlet valve: One or both coils may be open or restricted.
Low water pressure: Insufficient pressure preventing the valve from fully opening.
Clogged inlet screens: Debris obstructing water flow to the valve.
Wiring harness issue: Damaged or loose wiring to the water inlet valve.
Main Control Unit (MCU) failure: Rarely, the MCU may be sending incorrect signals.

Solution:

1

Disconnect power to the washer by unplugging it from the outlet or switching off the breaker.
2

Turn off the hot and cold water supply valves connected to the washer.
3

Disconnect the water supply hoses from the back of the washer. Inspect the inlet screens for clogs and clean if necessary.
4

Locate the dual water inlet valve, typically at the back of the washer near the hose connections.
5

Disconnect the wiring harness from the water inlet valve. Use a multimeter to check the valve coil resistance. A normal reading is typically between 500-1500 ohms for each coil. An open circuit indicates a faulty valve.
6

Remove the water inlet valve. This usually involves removing screws or clips securing it to the washer cabinet. A 1/4-inch nut driver or 5/16-inch socket may be required.
7

Install the new dual water inlet valve and reconnect the wiring harness. Reconnect the water supply hoses and turn on the water supply valves. Check for leaks.
8

Restore power to the washer and run a test cycle to verify proper operation.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed in a licensed technician setting. Be aware of 120V AC circuits inside the washer.

Prevention:

Periodically inspect and clean the inlet screens on the water supply hoses to prevent clogs. Check the water pressure to your home to ensure it meets the washer's requirements (typically 20-100 PSI).

Expert Tip:

After replacing the valve, run the washer through a calibration cycle if available in the service menu. This will ensure proper water level sensing and optimal wash performance. The service mode is typically accessed by pressing and holding specific button combinations simultaneously for a few seconds. Consult the service manual for exact instructions for your model. Forcing the water valve on through the diagnostic mode is a good way to confirm the valve opens.

Frequently Asked Questions

•What is the typical water pressure required for a GE Profile washer?

A GE Profile washer typically requires water pressure between 20 and 100 PSI.

•Where can I find the service manual for my specific GE Profile washer model?

You can usually find the service manual online by searching for your model number followed by 'service manual'. GE's website or appliance parts retailers are good starting points. You can try searching on reputable parts suppliers such as AppliancePartsPros.com.

•How do I test the pressure sensor to verify it is working correctly?

The pressure sensor can be tested with a multimeter by checking its resistance as you apply pressure to the sensor's air chamber. The resistance should change proportionally to the applied pressure. Consult the service manual for specific resistance values for your model.
