Wolf IR30450 and IR36550 Induction Range Code E01: Left Key Error

What E01 means

On Wolf induction ranges IR30450/S/T and IR36550/S/T from 2018 onward, E01 is a left key error: the control reports a key problem on the left secondary control board that serves the cooktop surface controls. Touches on the left side of the control area may not register, and the cooktop may stop responding. The same code on CT electric cooktops or integrated modules means something different.

Common causes of E01

Key on the left secondary control board stuck or not responding
Water, spill or cookware sitting on the left control area
Left secondary control board connection

✓ One safe check you can try

1. Stop all cooking and let the glass cool down. 2. Wipe the glass surface dry, especially the left control area. 3. Remove pans, towels, or utensils from near the touch controls. 4. Reset power at the breaker by waiting a minute off, then switching on. 5. If E01 returns, call us.

! Why to stop there

A stuck key from moisture can clear, but a failed board needs replacement.
Opening the cooktop to reach the board is not an owner task.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E01E01 questions

Is E01 the same on every Wolf cooktop?

No. On CT electric cooktops E01 relates to high ambient temperature, and on integrated modules it means an appliance type that is not valid. For IR30450 and IR36550 it is the left key error.

Could spills trigger it?

Yes. Liquid or objects on the controls can look like a stuck key. Dry the glass and clear the area, then reset power once. Pans, towels, and drips are the most common reasons, and a moment of cleaning often settles it.

When should I call?

If E01 returns after cleaning and one reset. We will confirm the cause and quote the repair in writing before work. Once that is done and the code returns, the left board is the next place we look.
