E01 — Door Lock Fault

Bosch's official US washer codes use an E:XX / F-code / icon format (e.g. E16/E34/F16/F34 for a door-lock fault); a bare 'E01' is not in the official US list. The 'door lock fault' explanation below is plausible given the code family but is not confirmed on Bosch's US consumer page — verify against your model's manual.

How to fix it

  1. Unplug the washer for 5 minutes to reset the control.
  2. Open the door, clear any clothing from the seal, firmly close, and retry.
  3. Inspect the door strike/hook for cracks; replace the hook kit if damaged.
  4. Remove the top panel and check the lock connector seating.
  5. Test the door lock PTC with a multimeter (should read several hundred ohms cold).
  6. Replace the door lock assembly if no continuity through the interlock circuit.
  7. If lock and wiring are good, the main control module is the next suspect.
