Quick answer
Seeing E33? On many Bertazzoni range units it relates to a temperature-sensor issue. Capture the model plate before resetting.
Model compatibility: Bertazzoni reuses codes across series and model years, so E33 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
If your Bertazzoni range shows E33, start from the idea of a possible temperature-sensing problem — then confirm in the manual. Do not open sealed, gas, or live panels to “prove” it. Photograph the full code and rating label before any reset or parts conversation.
Signs
Symptoms you may notice
The range displays E33 and temperatures seem off
E33 appears intermittently during operation
The range behaves inconsistently with E33 shown
Why it happens
Possible causes
A temperature sensor reading out of range

A control interpreting the reading as a fault
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 blocking internal vents or airflow
Note the actual behavior or temperatures if measurable
Perform a manufacturer-approved restart
Record the full Bertazzoni model and serial numbers before contacting a technician
Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. If you ever smell gas, stop immediately, do not operate any switches, leave the area and contact your gas provider and a qualified independent 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 adjust, disconnect or repair any gas connection or valve
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
E33 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.
You can safely try the basic checks above and one manufacturer-approved restart. If E33 returns, book Bertazzoni Appliance Repair rather than repeating resets.
Photograph the full code and rating label before any reset or parts conversation.
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.
