Convotherm E13/E23

What does Convotherm E13/E23 mean?

E13/E23 reports excess temperature of the steam generator or a steam generator sensor failure. The manual lists a steam generator sensor fault as the cause and directs the remedy to customer service. The control protects the steam generator by stopping operation when its temperature reading is too high or the sensor is unreliable.

Symptoms

• Display shows error code E13 or E23
• Steam functions stop working
• Steam generator temperature reads abnormally

Common causes

• Steam generator sensor fault
• Excess temperature in the steam generator

1. 01

   Allow the steam generator to cool

   If excess temperature triggered the code, letting the unit cool may let normal steam operation resume.

2. 02

   Power-cycle the unit

   Switch the combi off and on to confirm whether E13/E23 clears or returns.

3. 03

   Note when the code appears

   Record whether it shows during steam cooking to help the technician isolate the sensor.

4. 04

   Call customer service

   The manual directs the steam generator sensor fault behind E13/E23 to customer service.

When to call a professional

The manual attributes E13/E23 to a steam generator sensor fault and directs the remedy to customer service. If the code persists after the unit cools, stop using steam functions and contact a qualified Convotherm by Cleveland authorized service representative, since accessing and replacing the steam generator sensor involves hot components and internal wiring.
