Electronic Surface Element Control System (ESEC) Error Code Descriptions

When a specifi c error condition occurs in the ESEC system a code will be displayed in the electronic control panel. The error codes are displayed as
“CO” in the left display followed by the code number in the right display. For each Error Code there is a listing of the likely cause or failure condition, as well as
suggested corrective actions to be taken. Always reset the power by disconnecting or turning off the power supply for 30 seconds to see if the failure condition will
clear. If the error code returns perform the steps one at a time in the order listed below to correct the specifi c failure condition. NOTE: If multiple changing error
codes are displayed check for disconnected wires or cables.

correctly connected or
surface unit open.

Check the surface unit wire terminal connections. Ensure that they are properly
connected and tightened. Test continuity of element (should be less than 1 ohm).

Replace induction control assembly.

Steady "HE" in
display when cooking
zone is cold and
