Unox WC05

What does Unox WC05 mean?

WC05 is a fumes temperature warning on the hood accessory. The temperature of the fumes handled by the hood is outside the expected range. The oven can still be used while the hood function is impaired and the warning flags the abnormal fumes temperature.

Symptoms

• WC05 warning referencing the hood
• Abnormal hood fumes temperature
• Reduced extraction or condensation performance
• Warning recurs during operation

Common causes

• Restricted hood exhaust or airflow
• Hood fumes temperature probe out of range
• Hood not operating at correct speed
• Wiring fault to the fumes probe

Diagnostic steps

1. 01

   Check hood airflow

   Inspect the hood exhaust path for restriction or blockage.

2. 02

   Verify the fumes probe

   Confirm the hood fumes temperature probe is connected and reading plausibly.

3. 03

   Check hood operation

   Verify the hood fan runs at the correct speed during extraction.

4. 04

   Service the probe

   Replace the fumes probe or repair the wiring if the temperature reading is wrong.

When to call a professional

WC05 affects the hood accessory and the oven can still be used. Verifying the fumes probe and hood operation requires accessing the hood; have a qualified Unox technician investigate if basic airflow checks do not clear it.
