E23 GE washer error code: A troubleshooting guide

You’ve just loaded your washer, ready to tackle that mountain of laundry, when suddenly, your GE washer flashes a cryptic E23 error message. It’s the laundry equivalent of a “Do Not Pass Go” card, and it’s just as frustrating. But don’t throw in the towel yet! While an E23 error can be a head-scratcher, it’s not game over for your washing day.

The E23 error code may mean that there’s an issue with the foam water level switch on certain GE front-load washing machines. Check the diagnostic sheet for your washer model to find out if your washer is one of these.

To find the root cause, we’ll need to work through some troubleshooting steps. Let’s demystify the E23 error code so you can get your GE washer back in the spin of things.

While we strive to offer helpful advice for DIY appliance repairs, variations in models and configurations can lead to differences in troubleshooting steps, error codes and part replacements. For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.

Why the E23 error shows up

Your GE washer control board monitors water levels using a pressure switch connected to an air chamber at the bottom of the outer tub. As water enters the tub, air pressure increases in the chamber, closing internal switches at each water level threshold:

• Foam switch – Activates at approximately 2 1⁄2 inches below the door opening
• Main wash switch – Closes at approximately 1 1⁄2 inches below the door opening
• Overflow switch – Closes at approximately 6 1⁄2 inches above the door opening

The E23 error occurs when the foam switch incorrectly closes while the washer is in an idle state. The control board registers this as a potential overflow condition and activates the drain pump as a protective measure.

Some common reasons for the E23 error displaying on your washer include:

Troubleshooting steps

1. Check your washer load

Imbalanced loads that induce heavy vibration during fill can cause an E23 error.

To check for vibration issues:

1. Run a test cycle with a typical mixed load of laundry.
2. Place your hand on the top panel while the washer is filling to feel for any excessive shaking or vibration.
3. If there’s a strong vibration, redistribute the load to balance the tub weight.
4. Rerun the test cycle to see if the error code clears after correcting the excess vibration.

2. Check the water valve 

You’ll need to make sure the hot and cold water valves are working correctly. Leaking valves could slowly fill the tub and close the foam switch early.

To test the valves:

1. Enter service test mode t08 to activate the hot water valve (find out how to enter service mode by checking the tech sheet that comes with your washer).
2. Enter service test mode t09 to activate the cold water valve.
3. Listen closely for any trickling water when the valves are off.
4. Remove the hoses and check the valve screens for debris and blockages.
5. Make sure the valves shut off completely when the power is turned off.
6. Turn off the washer and measure the solenoid resistance with a multimeter. It should be approximately 1.1K ohms.

If you find any issues, replace the valve assembly.

3. Check the pressure switch 

1. Enter service test mode t06 to begin a fill test. The first display should be “E” indicating the empty tub.
2. Monitor the display for “F” at the foam level, “nl” at the main wash level, and “oF” at the overflow. If it skips “F” and jumps right to the main wash, the foam switch contacts are likely defective and need to be replaced.
3. Remove the pressure switch tube and check for any blockages. Remove any debris you find.
4. Use a multimeter to test the foam switch for continuity. You should get continuity if the tub is empty.

Replace the pressure switch if the contacts are defective or the readings are abnormal.

4. Check the drain pump 

1. Enter service test mode t05 to activate the drain pump.
2. Remove the plug (if your washer has one) and let the tub fully drain.
3. Remove the drain pump and check the impeller and housing for blockages.
4. Measure the pump motor winding resistance. It should be approximately 10.6 ohms. If it doesn’t, it needs to be replaced.
5. If the pump doesn’t empty the tub or the resistance is abnormal, replace the pump assembly.

5. Check the drain system

1. Remove the drain pump.
2. Clean the drain pump of any debris and clogs.
3. Examine the drain hoses for kinks, cracks, or blockages. Repair or replace them as needed.
4. Check that the standpipe diameter is 1 1⁄4” or larger and doesn’t exceed 96” in height.
5. Check for blockages at the standpipe inlet or inside the standpipe and remove any you find.

Last resort fixes

If all other components test normal, the water level control or main control board may be defective.

To replace the water level control:

1. Unplug the washer and turn off the water supply.
2. Remove the top panel, then disconnect the wire harnesses.
3. Detach the pressure tube from the water level control.
4. Rotate and remove the water level control assembly.
5. Install new water level control and reconnect all wiring
6. Plug the washer back in and turn it on to test its operation.

To replace the main control board:

1. Unplug the washer and disconnect the water lines.
2. Remove the top panel and detach all wire harnesses.
3. Remove the mounting screws and detach the main control board.
4. Install a new main control board and reconnect the wire harnesses.
5. Reassemble the washer, reconnect the power and water, and test it.
