Convotherm E02

What does Convotherm E02 mean?

E02 indicates the temperature in the oven's connection area has risen too high. According to the manual this is caused by a connection area ventilation fault or blocked air supply. The control flags the condition so the unit can cool; the manual notes you may allow the combi to cool or continue cooking at a lower oven temperature while arranging service.

Symptoms

• Display shows error code E02 for connection area temperature too high
• Connection area runs hotter than normal
• Reduced cooking performance until the unit cools

Common causes

• Connection area ventilation fault
• Air supply to the connection area blocked

Diagnostic steps

1. 01

   Allow the combi to cool

   The manual's first remedy is to let the oven cool down so the connection area temperature drops back into range.

2. 02

   Continue at a lower temperature

   If cooking must continue, the manual allows operating at a lower oven temperature to limit heat in the connection area.

3. 03

   Check for blocked air supply

   Inspect the connection area ventilation path for blockage, since a blocked air supply is one listed cause.

4. 04

   Call customer service

   The manual directs you to call customer service for the ventilation fault behind E02.

When to call a professional

If allowing the oven to cool and clearing any obvious air blockage does not stop E02 from returning, the manual attributes the fault to a connection area ventilation problem and directs you to call customer service. Diagnosing the ventilation fan and air paths inside the connection area requires a qualified Convotherm by Cleveland authorized service representative.
