Error codeE04
ApplianceWashing Machine
Quick answer
E04 on a Bertazzoni washing machine is associated with a door or door-lock condition. Review safe checks and model context before repair.
Model compatibility: Bertazzoni reuses codes across series and model years, so E04 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

On the current Bertazzoni service-site record, **E04** is associated with **a door or door-lock condition**. That description should still be checked against the documentation for the exact model before it is used to choose a component.
One normal owner-approved restart can be reasonable when the appliance has no leak, smoke, burning odor, arcing, gas odor, repeated breaker trip, uncontrolled heat, or other safety symptom. Record the code first. If it returns, repeated resets do not correct the underlying condition.
No. A code narrows a diagnostic path, and the exact model plus testing should confirm the failed component before parts are ordered.
The same display characters can be reused across appliance families and control generations. Code, appliance type, and model number belong together.
Photograph the display and the rating label with the full model number. If a visible leak, frost pattern, door condition, or installation issue is relevant, document that too without opening the appliance.
Only when operation is otherwise normal and there is no safety concern. Stop for smoke, burning odor, gas odor, arcing, repeated breaker trips, uncontrolled heat, active leakage, or unsafe refrigeration temperatures.
