Wolf Induction Cooktop Code E2: Coil temperature too high

What E2 means

On Wolf CI induction cooktops from the 2015-plus series with the EGO control, such as the CI304T/S, CI365T/S, and CI243C/B, E2 means the coil temperature is too high. The control sensed the induction coil running hotter than allowed and shut that zone down. The check starts with the cooling fan, any vent blockage, and the coil thermistor, which should read about 56k ohms at 22C. The display shows E2.

Common causes of E2

Cooling fan not running or not moving enough air
Vent area or air path blocked
Coil thermistor reading outside its normal range
Coil that really is overheating

✓ One safe check you can try

1. Turn off every zone and let the cooktop cool for 30 minutes. 2. Clear the vent area and anything stored close to the cooktop. 3. Use flat pans that fit the zone and avoid heating an empty pan. 4. Leave the breaker off for about a minute before switching it on again. 5. If E2 returns on a cool cooktop, stop and call us.

! Why to stop there

Telling a failed fan from a bad thermistor takes a meter and access under the cooktop.
Running a hot coil again and again can damage it.
A written price first, then the repair, then a 30-day workmanship warranty.

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.

E2E2 questions

Is E2 the same as E2 (CI/TM)?

They share the meaning, coil temperature too high. This page covers the CI induction cooktops from 2015 on; the integrated module cooktops have their own page.

What does the thermistor value mean?

The coil thermistor should read about 56k ohms at 22C. A reading far off that tells us the sensor, not the coil, is the problem.

Could my kitchen layout cause E2?

Poor airflow around the cooktop can. If the vent area is blocked or the fan struggles, the coil cannot shed heat, and we check that first.
