Electronic Surface Element Control System (ESEC) Error Code Descriptions
When a speci
fi
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 speci
fi
c failure condition.
NOTE: If multiple changing error
codes are displayed check for disconnected wires or cables.

unit and glass ceramic too
large.
Check whether the surface unit is properly positioned and touching the glass cooktop
