E01 on a Wolf induction range points to a specific control panel key fault — here’s Wolf’s own recommended first step.

A clicking igniter that won’t light is usually a simple fix, but there’s one specific scenario that means you should stop and call for help immediately.

The GR304 is Wolf’s all-gas counterpart to the dual-fuel range, using gas heat for both the cooktop and oven. Ignition-related faults are the most common service call on this model, on either the cooktop or oven side.

A dual-stacked burner that clicks but won’t light is one of the most common Wolf range service calls — and usually one of the more affordable fixes.

A little routine igniter care goes a long way toward preventing the most common Wolf range service call: clicking without lighting.
