How to Fix E23 Error (Step-by-Step)

Unplug the washing machine from the power source immediately and confirm the error stays cleared during a full test cycle.
Turn off the water supply to the washer at the wall valves.
Inspect the base of the machine for any visible signs of water leakage.
Check the AquaStop hose connections at both the tap and the machine to ensure they are tight.
Tilt the machine slightly to drain any water that may have collected in the base pan, which can trigger the sensor.
After ensuring there are no active leaks and the base is dry, plug the machine back in and turn on the water supply.
Run a short test cycle to confirm the error is cleared and no new leaks appear.
Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
