Wolf Cooktop Error Code E25

E25 indicates that the output driver watchdog circuit has detected an error on the module power board. The watchdog is a built-in monitoring function that watches the output driver stage and shuts down the cooktop if it detects abnormal behavior. This is a protective fault designed to prevent damage to other components. The cooktop will not operate until the fault is cleared or the board is replaced.

A power cycle reset is the recommended first step and can clear the error if the fault was caused by a transient power issue or a temporary logic fault. Turn off the breaker or unplug the unit for about one minute before restoring power. If E25 returns after the reset, the underlying hardware fault on the module power board has not been resolved and the board will need to be inspected or replaced.

Repair costs vary depending on the specific model and whether the module power board needs replacement. Board replacement parts for Wolf cooktops typically range from $150 to $400 or more, and professional labor charges generally add $100 to $200 depending on your location and the service provider. If the error clears with a simple power cycle and does not return, there may be no parts cost at all.

The first step you can try is cycling the unit power by switching off the circuit breaker or unplugging the cooktop for at least one minute, then restoring power. If the error clears and does not return, no further action may be needed. However, if E25 comes back, the module power board will need to be replaced, which is a repair best handled by a qualified technician due to the high-voltage components involved.

No. When E25 is active, the cooktop's control system has detected a fault in the output driver stage and has halted normal operation as a safety precaution. Attempting to bypass or ignore this error and continue using the cooktop is not recommended, as the fault could indicate a failing power board that may pose a risk of further electrical damage. Keep the unit off until the fault is diagnosed and resolved.
