Smeg W02 Error Code

What does Smeg W02 mean?

Smeg shows W02 as a warning with the description "MOTOR RPM NOT DETECTED". The control system is not reading the fan motor's rotation speed, so it warns that motor feedback is missing. This can indicate the fan is not turning as expected or that its speed signal is not reaching the controller.

Symptoms

• Display shows the W02 warning
• On-screen description reports motor RPM not detected
• Fan may not be turning as expected
• Cooking performance may be uneven if airflow is affected

Common causes

• Fan motor speed signal not detected by the controller
• Fan motor not turning
• Damaged or disconnected motor feedback wiring
• Faulty motor or speed sensor

Diagnostic steps

1. Power-cycle the oven

   Switch the oven off at the main power switch and back on to clear a transient warning reading.

2. Listen for the fan

   Observe whether the fan motor runs during a cycle, since the warning indicates its speed is not being detected.

3. Record the appliance details

   Have the model and serial information ready so a technician can identify the correct motor and feedback parts.

4. Contact the Technical Assistance Service

   If W02 persists, contact Smeg Technical Assistance, as missing motor feedback points to a fault needing service.

When to call a professional

Diagnosing why the motor's speed is not detected requires checking the fan motor, its feedback wiring and the controller, which sits inside the appliance among mains-voltage components. The manual instructs you to always contact the Technical Assistance Service for these messages, so call a qualified Smeg technician rather than opening the appliance to inspect the motor yourself.
