How to Fix E12 Error

This is an overflow error. Unplug the washer and shut off the water supply immediately.
Manually drain the washer using the emergency drain hose, usually located behind a small access panel on the bottom front.
Check the pressure sensor air tube for clogs or kinks. If the tube is clear, the pressure sensor itself may be faulty. Replace it.
If the problem continues after replacing the sensor, the water inlet valve is likely stuck open and needs to be replaced.
