Code E3
high severity
Bosch models: Bosch front-load washers (WAx/WGx in Europe; 300/500/800 series in North America) have a two-part filter: a flat mesh pre-filter and a cylindrical coin-trap, both behind the lower-front service flap. The EcoSilence brushless motor runs quietly — lower vibration than typical is normal, not a fault.
Common causes
- Too much detergent used
- Non-HE detergent used in a high-efficiency machine
- Detergent residue buildup in the drawer or drum
Step-by-step fix
- Do not add more detergent.
- Select a rinse-and-spin cycle to clear the suds.
- Clean the detergent drawer thoroughly.
- Run a hot maintenance cycle with no detergent.
Tools you may need
None
Prevention
- Use HE-rated detergent only.
- Use the recommended dose (half is often sufficient).
- Clean the drum and drawer monthly.
When to stop DIY
