Electrolux Professional ESCH

What does Electrolux Professional ESCH mean?

ESCH means the SkyLine oven's electronic component compartment is over-temperature. The oven stops, except for the cooling fan, to protect its electronics. It is commonly caused by a dirty filter, excessive room temperature, or insufficient cooling airflow to the electronic compartment, and clears once the compartment cools.

Symptoms

• ESCH displayed; oven stops but cooling fan runs
• Hot electronic compartment
• Often follows a dirty air filter
• May occur in a hot kitchen

Common causes

• Filter is dirty
• Too high room temperature

Diagnostic steps

1. 01

   Keep the oven powered for cooling

   Allow the cooling fan to run so the compartment temperature can decrease.

2. 02

   Check room temperature

   The oven needs fresh air to cool its electronic compartment; a hot room worsens the condition.

3. 03

   Clean the filter

   Clean the air inlet filter so cooling airflow is restored.

4. 04

   Let the oven cool before cooking

   Allow the oven to cool before resuming cooking.

5. 05

   Call Service if it recurs

   Call Service if the problem reoccurs after cleaning and cooling.

When to call a professional

Staff can usually clear ESCH by cleaning the filter and improving airflow. Call an Electrolux Professional engineer if the over-temperature recurs despite a clean filter and reasonable room conditions, which can point to a cooling-fan fault or airflow obstruction inside the appliance. Repeated electronic-compartment overheating threatens the control electronics, so professional inspection is warranted when basic remedies fail.
