Diagnostics and Service Information
Failure Codes
The cooktop operates a self-diagnostic mode when power is applied. The touch board has error codes that
can be utilized by the service technician in order to quickly identify failed or improper operation of certain
cooktop components. To access failure codes, simultaneously press the TIMER ON/OFF and CONTROL LOCK
pads for approximately 10 seconds . Error codes will blink in the window of the corresponding element. The
replacement of the failed component will clear the error code.
Whenever a failure code is encountered and before attempting to replace any components:
1.
Turn off the power supply for 30 seconds, then reset it to see if this clears the failure code.
2.
Verify proper voltage and orientation of the power supply wiring connections.
