How to Fix FE/AE(RE) Error

This usually indicates excess suds (similar to bE) or a slight overfill.
If suds are visible, pour milk or oil into the tub to disperse them.
Verify the dishwasher is leveled properly; if tilted forward, the sensor may trip prematurely.
If the error persists, treat it as a hard AE (Leak) or FE (Valve) failure.

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