Bertazzoni Microwave ERROR-SENSOR-COOK Error: Sensor cooking humidity fault
What Does ERROR Mean During Sensor Cooking on a Bertazzoni Microwave? ERROR during a sensor cooking cycle on a Bertazzoni microwave (including the MO30 STA NE and MD24X drawer models) means the absolute humidity (AH) sensor did not detect food vapour within the required detection window. Sensor cooking works by waiting for steam to rise […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. The sensor cook function is not usable until the AH sensor is confirmed working; however, manual time cooking remains safe to use on the same microwave.
Can I reset the code?
Yes. Pressing Stop/Clear resets the ERROR state. If the sensor itself has failed, ERROR will recur on every sensor cooking attempt until the sensor is replaced.
When to stop immediately?
Stop if you notice: ERROR appears on every sensor cooking attempt even with vented covers., Manual cooking functions also begin to malfunction..
Symptoms You May Notice
Microwave shuts off during sensor cooking cycle
The oven stops running partway through a sensor cook program — either within the first 16 seconds or after 5 minutes — before the food has completed cooking.
Sensor cook cycle cannot be restarted automatically
After the shutdown the display shows ERROR and the cycle does not resume; the user must press Stop/Clear and switch to manual cooking.
Possible Causes
AH sensor failed or disconnected
The absolute humidity sensor has malfunctioned or its connector has come loose, so no vapour signal reaches the control unit during the detection phase.
Requires ProfessionalSteam blocked from reaching the sensor
Food is covered with plastic wrap or a tight lid that is preventing steam from venting and reaching the sensor during the first detection stage.
DIY PossibleDoor opened or cycle interrupted
The oven door was opened or Stop/Clear was pressed during the 16-second initial sensor window, aborting the detection phase.
DIY PossibleSafe Checks You Can Do
-
1
Switch to manual cooking
Press Stop/Clear to dismiss the ERROR display, then cook the food manually using time and power level rather than the sensor cooking function.
Sensor cooking is optional; manual time cooking is fully reliable on all Bertazzoni microwave models.

2
Retest sensor cooking with vented cover
If you want to retest sensor cooking, use vented microwave-safe covers or loosely draped paper towel — not tight lids — so steam can reach the sensor freely.
Do not open the door during the first 16 seconds of a sensor cook cycle; early opening resets the detection window and triggers ERROR.
When to Call a Professional
Contact a qualified technician if:
- ERROR recurs consistently on sensor cooking with correct vented food covers.
- AH sensor resistance or output is outside the specified range.
- Control unit diagnostic confirms sensor signal absent.
