Wolf Induction Range Cooktop Code E15: Generator voltage too low

What E15 means

On Wolf IR30450 and IR36550 induction ranges from 2018 on, such as the IR30450/S/T and IR36550/S/P, code E15 on the cooktop means a power supply error on the generator. The generator voltage is too low, so the module that drives the induction coils is not getting what it needs. You will see E15 and the cooktop may not heat at all, or may heat weakly.

Common causes of E15

Low supply voltage reaching the generator
Generator power supply that is failing
Loose connection feeding the generator

✓ One safe check you can try

1. Turn all zones off. 2. Remove power at the breaker for a minute and then bring it back. 3. Check whether other appliances on the circuit seem weak, which hints at a supply issue. 4. If E15 returns, stop using the cooktop and call us. Do not test the outlet yourself.

! Why to stop there

Low voltage can come from the home supply or from the generator, and we measure to tell which.
Power supply work is not safe for owners.
Written price first, and repairs come with a 30-day 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.

E15E15 questions

What does E15 mean?

It means the generator's voltage is too low. The generator needs enough power to drive the induction coils, and the control stops heating when it is short.

Could my house wiring be the cause?

It can. A weak supply affects the generator. We check the range first and tell you if an electrician is needed. We explain what we find in plain words, and you only pay for what is needed.

Will resetting help?

A reset may clear a one-time dip. If E15 returns, the generator or its supply needs testing, and we quote before starting. We would rather test than guess, and the repair carries a 30-day workmanship warranty.
