Unox WS01

What does Unox WS01 mean?

WS01 is a power board over-heating warning on the static oven accessory. The static oven's power board is running too hot. As a warning the accessory continues with reduced function while flagging the overheating electronics, usually a cooling or installation issue.

Symptoms

• WS01 warning referencing the static oven
• Static oven power board running hot
• Warning during extended use
• Warning clears as the board cools

Common causes

• Inadequate cooling of the power board
• High ambient temperature around the accessory
• Cooling airflow issue
• Power board fault

Diagnostic steps

1. 01

   Allow cooling

   Let the static oven cool and check whether the warning clears.

2. 02

   Check cooling airflow

   Verify cooling airflow over the board and adequate clearance around the accessory.

3. 03

   Check the installation

   Confirm the accessory is installed per the manual with proper ventilation.

4. 04

   Service the board

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

When to call a professional

WS01 affects the static oven electronics. Diagnosing the cooling and power board requires accessing the accessory and mains-voltage work; have a qualified Unox technician investigate if a cool-down does not resolve it.
