Unox WC02

What does Unox WC02 mean?

WC02 is a power board over-temperature warning on the hood accessory. The hood's power board is running too hot. Because it is a peripheral, the oven can still be used while the hood function is restricted and the warning flags the overheating electronics.

Symptoms

• WC02 warning referencing the hood
• Hood power board running hot
• Hood function restricted, oven still usable
• Warning clears as the board cools

Common causes

• Inadequate cooling of the hood power board
• High ambient temperature around the hood
• Cooling airflow issue
• Hood power board fault

Diagnostic steps

1. 01

   Allow cooling

   Let the hood cool and check whether the warning clears.

2. 02

   Check cooling airflow

   Verify cooling airflow over the hood board and clearance around the hood.

3. 03

   Check the installation

   Confirm the hood is installed per the manual with adequate ventilation.

4. 04

   Service the board

   If overheating continues with correct cooling, have the hood power board checked and replaced if faulty.

When to call a professional

WC02 affects hood electronics. Diagnosing the cooling and the hood power board requires accessing the hood and mains-voltage work; have a qualified Unox technician investigate if a cool-down does not resolve it.
