Quick answer
E01 — commonly associated with a door/lock issue on a Bertazzoni microwave. Meaning can vary by model; verify before relying on it.
Model compatibility: Bertazzoni reuses codes across series and model years, so E01 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Seeing this code on your Bertazzoni appliance?
Book a specialist visit for a clear estimate and approval before any repair. Independent service — not an official Bertazzoni service center.
Avoid clearing E01 over and over to force a cycle. Capture it, complete only manual user steps, then let Bertazzoni Appliance Repair test if it sticks.
Not necessarily. Bertazzoni reuses codes across series and years. Record your full model number so Bertazzoni Appliance Repair can interpret E01 correctly.
No. Bertazzoni Appliance Repair publishes independent repair guidance for homeowners. Use your Bertazzoni model manual for manufacturer wording, then book an independent technician if the fault continues.
