Error codeE5
ApplianceRefrigerator
Quick answer
E5 is the freezer frost sensor on refrigerators and a middle zone probe open circuit on the wine cooler.
Model compatibility: Bertazzoni reuses codes across series and model years, so E5 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
E5 is a freezer frost (defrost) sensor failure on Bertazzoni refrigerators and an open circuit on the middle zone in-cabinet probe of the wine cooler.
E5 on the refrigerator
Three manuals phrase this fault differently while pointing to the same freezer sensor, the one connected with frost and defrosting.

Frosting sensor for freezing fault
According to the last two, the refrigerator can still cool and freeze while E5 is shown; they ask that the owner contact service to keep normal operation.
E5 on the wine cooler
On the cooler the code sits in the middle zone row, described as an open circuit on the in-cabinet probe. E6 covers the short circuit. The alarm is the same as for other probe codes: three tics, a flash of the code roughly every ten seconds, and the on/off key to quiet it.
Steps
Write the code and the compartment down.
Silence the alarm.
Arrange a repair. No reset is published for E5.
Reading the display
A locked 36 inch refrigerator shows the code in its temperature zone. The cooler flashes it on a cycle, so if you only saw it for an instant, wait for the next flash. A misread digit points to the wrong entry.

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.
