Wolf Induction Range Cooktop Code E09: Coil over temperature

What E09 means

On Wolf IR30450 and IR36550 induction ranges from 2018 on, such as the IR30450/S/T and IR36550/S/P, code E09 on the cooktop means a coil over temperature. Unlike E05, this is a zone error, and E09 shows on the zone that is too hot. The induction coil under that zone sensed excess heat, so it cut power. Empty or dry cookware and poor pan contact are common reasons.

Common causes of E09

Pan left empty or boiled dry on that zone
Cookware with a warped or uneven base
Coil or its temperature sensing reading too high
Cooling problem under the cooktop

✓ One safe check you can try

1. Turn the zone off and remove the pan. 2. Let the cooktop cool for 30 minutes. 3. Try a different, flat-bottomed induction-ready pan with liquid in it. 4. If E09 returns on the same zone with a good pan, call us. 5. Mention the model number when you call, and we will plan the visit.

! Why to stop there

The same code on one zone points to that coil or its sensor.
Replacing a coil without testing wastes money.

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.

E09E09 questions

Why does E09 only show on one zone?

It is a zone error, so only the over-temperature coil reports it. The rest of the cooktop may keep working. Our technician checks the likely causes in order, and the repair carries a 30-day workmanship warranty.

Can an empty pan cause it?

Yes. A pan with no liquid heats quickly and can push the coil past its limit. Try a flat pan with water in it after cooling down.

What if it keeps coming back?

Then the coil or its sensor needs testing. Call us, and we will quote the repair in writing first. A short description of what you saw helps, and we tell you the result of each check.
