Frequently Asked Questions

What does Error E90 mean on an AEG washing machine?

E90 is a catch-all electronics fault code indicating the main control board has detected an internal communication error or a component it cannot identify. It usually requires a service call.

Can a power surge cause AEG Error E90?

Yes — a sudden power cut or voltage spike during a cycle can corrupt the control board state and cause E90. A full power reset (5 minutes unplugged) often resolves surge-related E90 faults.

Is E90 on an AEG washer a serious fault?

E90 can range from a minor transient glitch (resolved by reset) to a failed control board requiring replacement. If it recurs after multiple resets, the machine needs professional attention.
