Quick answer
E34 · a door/lock issue · Bertazzoni range — independent summary for homeowners.
Model compatibility: Bertazzoni reuses codes across series and model years, so E34 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
On many Bertazzoni range models, E34 is commonly tied to a possible door or door-lock problem. Series and control generations differ — confirm the wording in your model documentation before acting. If your manual lists a different description for this code, trust the manual over any general summary.

Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. If you ever smell gas, stop immediately, do not operate any switches, leave the area and contact your gas provider and a qualified independent technician. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.
Please avoid
