Quick answer
Seeing F12? On many Bertazzoni refrigerator units it relates to a door/lock issue. Capture the model plate before resetting.
Model compatibility: Bertazzoni reuses codes across series and model years, so F12 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 refrigerator controls may raise F12 when a possible door or door-lock problem is involved. Record the full model number; the same characters can map differently across years. Treat this as independent homeowner guidance from Bertazzoni Appliance Repair, not a substitute for model-specific service literature.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Confirm nothing is obstructing the door
Check the door closes and latches cleanly
Allow the appliance to cool if it was hot, then retry
Write down when F12 appeared and which cycle or mode was running
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
F12 that survives basic checks belongs with independent service. Bertazzoni Appliance Repair verifies the cause against your model documentation first.
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.
Clearing the display is fine once notes are saved — it is not a repair. When F12 comes back on the next use, contact Bertazzoni Appliance Repair.
If two manuals disagree about F12, trust the literature for your exact model — then book independent help if the fault continues.
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.
