AEG
Washer
Code DE
low severity
AEG models: AEG is owned by Electrolux and shares the same platform. The pump filter is behind the lower-right service panel. AEG's ÖKOMix technology pre-mixes detergent with water before the main cycle — the brief agitation before fill begins is a designed pre-wash, not a fault.
Common causes
- Door not closed firmly enough to engage the latch
- Object caught in the door seal preventing full closure
- Worn or broken door latch/catch
- Door lock wiring harness loose
Step-by-step fix
- Open the door and check the rubber seal for small items of clothing caught in it.
- Close the door firmly — listen for a click.
- Inspect the latch hook and catch for visible damage.
- If the door closes but the error persists, the door lock module may need replacement.
Tools you may need
FlashlightScrewdriver set (if replacing lock)
Prevention
- Check the door seal for small items after each load.
- Do not overstuff the drum, which puts pressure on the door seal.
When to stop DIY
Call a technician if the lock clicks but the machine still shows the error — the lock module's internal microswitch has likely failed.
