ELECTRONIC SURFACE ELEMENT CONTROL (ESEC 30) TROUBLESHOOTING GUIDE
- Wave Touch Models-
When a failure occurs in the ESEC system the control
will beep and usually display an error code. These error
codes will appear in two front element displays. The left
side will display the letter E and the right side will display
the error code number. (Fig 1). In some cases the control
may beep and display only the letter “ E “ in the left
display or there may be no display in either window.

The troubleshooting guide below provides a listing of the likely failure condition or cause, as well as
suggested corrective actions to be taken. Perform the steps one at a time in the order listed below to
correct the specific failure condition.
The ESEC 30 Electronic Surface Element Control System operates the radiant surface elements and
warming zone element. The ESEC 30 UIB receives the operator selection from the TST panel and
signals the ESEC 20 Surface Unit Control Board (relay board) which then closes the appropriate relay
to turn on the desired element.
If a failure occurs in the ESEC system there are several error codes that may be displayed to guide
the service technician in diagnosing the failure.
It is important to note that the error codes are displayed are differently between the “A” models with
Wave-Touch™” display and the “B” model with “ IQ Touch™” display. Although the display method is
different the potential failure conditions and possible cause are the same.
