Quick answer
E12 · a door/lock issue · Bertazzoni wine cooler — independent summary for homeowners.
Model compatibility: Bertazzoni reuses codes across series and model years, so E12 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
Bertazzoni wine cooler controls may raise E12 when a possible door or door-lock problem is involved. Record the full model number; the same characters can map differently across years. Bertazzoni Appliance Repair uses the code as a starting clue; final diagnosis still follows your appliance’s documentation.

Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. Never open the sealed cooling or refrigerant system — this must be handled by a certified 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
What not to attempt
Do not open internal panels or access high-voltage components
Do not open or attempt to recharge the sealed refrigerant system
Do not bypass door locks, safety switches or interlocks
Do not keep running the appliance if there is water near electrical parts, a burning smell or sparks

When to call a technician
