GE Washer Error Code 22: Water Fill Time Exceeded... | appliancefaults.com

Technical Background:

The MCU monitors the water level through a pressure sensor or switch. It opens the water inlet valves and expects the water level to reach a certain point within a specific timeframe. If this timeframe is exceeded, the MCU throws error code 22 and shuts down the water fill process. The MCU supplies 120V AC to the water inlet valves.

Symptoms:

US homeowner reports the GE washer displays error code 22 and stops mid-cycle. The washer may not fill with water at all, or it fills very slowly.

Possible Causes:

Low water pressure to the washing machine.
Clogged water inlet valve screens.
Defective water inlet valve(s).
Faulty pressure sensor or pressure switch.
Kinked or blocked water supply hoses.
Problem with the main control board (MCU).

Solution:

1

Turn off the water supply to the washing machine at the shut-off valves.
2

Unplug the washing machine from the outlet.
3

Disconnect the water supply hoses from the back of the washer using pliers.
4

Inspect and clean the inlet valve screens. Use a small brush to remove any debris.
5

Use a multimeter to test the water inlet valve solenoids for continuity. A reading of around 1k-3k ohms is typical. Replace the valve if open or shorted.
6

Inspect the pressure switch/sensor and the hose connected to it for damage or blockages. Test the continuity of the pressure switch with a multimeter.
7

Reassemble the washing machine and test its operation.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energization. Be aware of high voltage (120V AC) when testing components.

Prevention:

Periodically inspect and clean the water inlet valve screens to prevent clogs. Check water hoses for kinks and replace them every 5 years.

Expert Tip:

To enter service mode on some GE washers, press and hold the Start/Pause and Temp buttons simultaneously for 3 seconds. This will allow you to run diagnostic tests and clear error codes.

Frequently Asked Questions

•What is the typical water fill time before the error code 22 is triggered?

The typical fill time before error code 22 is triggered varies by model, but it's usually around 8-10 minutes. Refer to the service manual for the specific model.

•How do I test the pressure switch/sensor with a multimeter?

With the washer empty and disconnected from power, use a multimeter to check continuity across the pressure switch terminals. Then, gently blow into the pressure switch hose. You should hear a click and the continuity should change. Replace if it doesn't function as described.

•Where is the main control board (MCU) located in a GE washer?

The MCU is typically located behind the control panel at the top of the washer. You'll need to remove the control panel to access it. Be careful of sharp edges and static electricity.
