Wolf Cooktop Error Code E23

E23 indicates that the temperature sensor for the Generator 2 front-left burner has an open circuit condition. The control board detected that the sensor's analog-to-digital value exceeded the error limit, which triggered an automatic shutdown of that burner. The fault is isolated to the front-left burner position and does not affect other burners on the cooktop.

The cooktop automatically shuts down the front-left burner when E23 is active, so that specific burner will not operate. Other burners on the cooktop may continue to function. It is not advisable to attempt to bypass the fault, as the temperature sensor is part of the burner's thermal management and safety system.

Repair costs for E23 vary depending on whether the generator board, the sensor, or only a wiring connection needs to be addressed. Generator board replacements on Wolf cooktops typically involve parts costs in the range of $150 to $400 or more, plus labor fees that can range from $100 to $250 depending on your location and service provider. Getting a diagnostic estimate from a Wolf-authorized service technician before authorizing repairs is recommended.

The primary diagnostic step for E23 is replacement of the affected generator board, which is a technical repair involving disassembly of the cooktop and handling of electrical components. While a knowledgeable DIYer may be able to inspect wiring and connectors, replacing the generator board is generally best handled by a qualified appliance technician to ensure correct installation and safe operation.

A power reset may temporarily clear the displayed error, but E23 will return if the underlying cause, whether a failed generator board, open sensor, or wiring fault, has not been corrected. The burner will shut down again once the control detects the out-of-range A/D value during operation. A proper repair of the root cause is required to permanently resolve the fault.
