Error codeE12

Quick answer
E12 is a short circuit on the lower zone frosting probe.
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 lists E12 for its wine cooler as a short circuit on the lower zone frosting probe.
Summary
E12 means a short circuit on the lower zone frosting probe. It sits in the final row of the error table in the wine cooler manual, and that table gives the same direction for all codes: a service technician does the repair.
Two faults per probe
Open circuit, the loop is broken: for this probe, E11.
Short circuit, the loop is bridged: for this probe, E12.
Telling them apart gives the technician a starting point, though testing it needs a meter and access to the wiring.
Alarm behavior
A fault triggers three tics from the buzzer, a code that flashes about every ten seconds, and a repeating alarm. The on/off key stops the sound. A single tic on each key press is ordinary and not part of the fault.
Please avoid
Pulling the cooler out to pry at the probe.
Cutting power again and again in the hope that the code vanishes.
No reset is published, and nothing suggests restarting clears a probe fault.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
