Error codeE01
ApplianceRefrigerator
Quick answer
E01 typically points to a sensor or control communication fault in the refrigerator.
Model compatibility: Bertazzoni reuses codes across series and model years, so E01 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
The E01 code generally indicates the refrigerator’s control detected a sensor or communication issue. It is a signal to have the control and sensors evaluated rather than a specific user-fixable step.

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 the refrigerator has stable power
Check that vents inside are not blocked by items
Note the actual temperatures if you can measure them
Important safety warning. Sealed refrigerant systems and control electronics require professional tools. Avoid internal disassembly and protect food safety if temperatures are drifting.
Please avoid
What not to attempt
Do not open sealed refrigerant components
Do not access internal control wiring
Do not rely on repeated power cycling as a fix

When to call a technician
If E01 persists and temperatures drift, book a diagnosis so the sensor and control can be evaluated before food safety is affected.
