ELECTRONIC SURFACE ELEMENT CONTROL SYSTEM (ESEC 30) ERROR CODE DESCRIPTIONS
When a specific error condition occurs in the ESEC system, the control will beep and usually display an error code. These error codes will
appear in the two front element displays with "E" in the left display and the code number in the right display. For each Error Code or symptom
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 specific failure condition. NOTE: If multiple changing error codes are displayed check for disconnected wires or cables.

Suggested Corrective Action
Use larger pan or this pan on a smaller cooking zone. Refer to
owners guide for proper pan selection.
Check whether the pots or pans are suitable for induction.
Refer to owners guide for proper pan selection.
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).
Check whether the surface unit is properly positioned and
touching the glass cooktop surface.
1. Follow instructions for proper use of touch controls.
2. Verify harness going between UIB ribbon connectors and
touch panel connectors. Replace if defective or damaged.
3. Verify there is no mechanical interference close to the
touch panel (wires, utensils, etc.).
4. Replace touch panel.
5. Replace UIB.
Clean up spills or remove objects. Restart cooktop in normal
manner.
Clear vent openings.
.
Follow owner's guide for proper pan selection
Check whether the surface unit is properly positioned and
touching the glass cooktop surface.
1. With two surface units operating, verify that the fans
run at a slow speed. If fans do not run, check for
foreign objects or stuck fan motor.
2. Test continuity of motor windings. Replace motor if open.
3. Replace filter board.
1. Test surface unit RTD approx. 1K ohms at room temperature.
Replace surface unit if resistance is not correct.
2. Replace generator board.
Verify installation and harness connections to UIB
1. Check for 120 volts AC at the power supply board connector
P1 between pins 1 and 4. Test harness if voltage is not present.
2. Test for 8 volts DC output at the power supply board connector
P3 between Pins 1 and 2. Replace power supply board if
voltage is not correct.
3. Test for 16 volts DC at output at power supply board connector
P3 between Pins 1 and 3. Replace power supply board if voltage
is not correct.
Replace UIB.
