Quick answer: Excess suds condition

What you’ll notice

Cycle pauses and an over-sudsing warning displays; drum rotates slowly to dissipate foam.

Bosch Washer 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

  1. Do not add more detergent.
  2. Select a rinse-and-spin cycle to clear the suds.
  3. Clean the detergent drawer thoroughly.
  4. Run a hot maintenance cycle with no detergent.

Tools you may need

Prevention
