AEG washer dryer EFO error code
What EFO means on an AEG washer dryer
Anti-flood protection triggered, usually by water in the base from a leak or overfill.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
The EFO code on an AEG washer dryer means the anti-flood protection has been triggered. This usually happens because water has collected in the base of the machine, either from a leak or from the machine overfilling. It tends to show up alongside the machine leaking.
Engineers sometimes find that the leak is coming from the soap drawer, for example where the drawer has cracked, or where the housing it slides into has become misshapen after a damaged drawer has been forced in and out.
An engineer will typically start by looking closely at where the water is coming from, checking the soap drawer and the housing around it. Where the drawer is cracked, they usually replace it, and the detergent housing and the part that carries water into it may be replaced as well. These parts often have to be ordered, so the repair may be finished at a second visit. Once the new parts are in, the engineer runs the machine to make sure it is no longer leaking.

Before you check anything yourself
- Switch the washer dryer off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the washer dryer apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
