Convotherm E22

What does Convotherm E22 mean?

E22 reports a core temperature sensor fault. The core temperature probe measures the internal temperature of food during probe-based cooking. When the control detects a fault with this sensor it displays E22; the manual's remedy is to set a cooking program with time instead and to call customer service for the sensor itself.

Symptoms

• Display shows error code E22 for core temperature sensor fault
• Probe-based cooking programs will not run correctly
• Core temperature reading is missing or erratic

Common causes

• Core temperature sensor fault

Diagnostic steps

1. 01

   Switch to a time-based program

   The manual's remedy is to set a cooking program with time so cooking can continue without the probe.

2. 02

   Inspect the probe and connection

   Check the core temperature probe and its hanger for obvious damage before assuming an internal fault.

3. 03

   Power-cycle the unit

   Switch the combi off and on to confirm whether the fault clears.

4. 04

   Call customer service

   The manual directs the core temperature sensor fault behind E22 to customer service.

When to call a professional

You can keep cooking with time-based programs, but the manual directs the core temperature sensor fault itself to customer service. If the probe is visibly intact and E22 still appears, contact a qualified Convotherm by Cleveland authorized service representative to test and replace the core temperature sensor so probe cooking works reliably again.
