Error Code Explained
What Does the Wolf E2 Error Code Mean?
E2 on a Wolf induction cooktop indicates a fault in the IGBT (insulated gate bipolar transistor) power inverter bridge for one or more induction zones. The IGBT transistors generate the high-frequency alternating current that drives the induction coil. An IGBT fault disables the affected zone and may disable the entire cooktop as a protective measure.
Root Causes
Common Causes of the Wolf E2 Error Code
-
1Failed IGBT Transistor in Inverter ModuleOne or more IGBT transistors in the inverter bridge have failed — typically from thermal stress or power surge.
-
2Power Surge Damage to InverterA voltage spike has damaged IGBT transistors or gate drive components in the inverter module.
Step-by-Step Guide
How to Troubleshoot the E2 Error Code
Safety First: Always disconnect the Cooktop from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.
-
1Power ResetSwitch off the cooktop circuit breaker for 60 seconds and restore power. If E2 clears, monitor closely for recurrence.

When to Call a Wolf Technician
E2 requires professional diagnosis and inverter module replacement. IGBT repair is not feasible at the component level in the field.
FAQ
Frequently Asked Questions — Wolf E2
-
In some configurations, E2 on one zone allows other zones to function. However, if the cooktop has shut down completely, do not use any zone until E2 has been professionally diagnosed — an IGBT fault can produce secondary failures if the cooktop continues to operate.
