Wolf Module Cooktop Code E22: Configuration data corrupted in memory

What E22 means

On Wolf integrated module cooktops from the 2015 series, such as the CE152TF/S and SM15TF/S, E22 means the configuration data stored in EEPROM memory is corrupted. The control can no longer rely on its stored setup, so it stops normal operation. The display shows E22, and the cooktop may not heat. Owners cannot rewrite this data from the controls, so it typically needs a technician.

Common causes of E22

Setup data in the EEPROM memory corrupted
Control board with failing memory
Power interruption that disturbed stored data

✓ One safe check you can try

1. Turn all modules off. 2. Take power off at the breaker for one minute and then bring it back. 3. See whether the display starts normally. 4. If E22 returns, stop using the cooktop and call us with the model number from its label.

! Why to stop there

Corrupted memory cannot be repaired by pressing buttons, so retries waste time.
Reloading or replacing a control needs the right model data and tools.
We state the price in writing before anything is touched, with 30 days of workmanship coverage.

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.

E22E22 questions

What is EEPROM?

It is the memory where the control keeps its setup. E22 means the configuration data in that memory is corrupted and cannot be trusted. We confirm the reading on site before we quote anything.

Is E22 the same as E23?

They are neighbors. E22 concerns the configuration data, while E23 concerns the user option data, so a technician checks different stored settings. Give us your model number and we will arrive with the right parts.

Will I lose my settings?

If the stored data is corrupted, the control may restore defaults or need replacement. We explain the plan and the price in writing before we begin.
