Wolf Induction Code E22: open burner sensor on generator 1

What E22 means

On earlier Wolf CT induction cooktops, including the CT30 and CT36 sizes, E22 and E23 mean a generator burner sensor reads open. E22 points to generator 1, covering the F, FR and FC burners, while E23 covers generator 2, the FL burner. The affected burner shuts down. You will see the code in the display and one cooking position that will not heat even though the rest may work.

Common causes of E22

Burner sensor circuit open or its connection loose
Generator board input reading the sensor as open
Burner sensor damaged

✓ One safe check you can try

1. Turn off all burners and let the glass cool. 2. Switch the cooktop breaker off for a minute and on again. 3. Try the same burner once; if E22 reappears, stop. 4. Do not lift the glass or touch internal wiring. 5. Call us for a diagnosis and a written price.

! Why to stop there

An open sensor circuit does not heal and keeps one burner disabled.
Locating the open part means testing inside the unit near high voltage.
We tell you the cost in writing first and back the work with 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.

E22E22 questions

Which burners does E22 cover?

E22 relates to generator 1, which feeds the F, FR and FC burners. E23 relates to generator 2 and the FL burner. We schedule within a three-hour window and call ahead before arriving.

Is E22 an overheat code?

No. It is a sensor reading open, not a temperature limit. Cooling the cooktop will not clear it unless the connection is restored. Avoid forcing buttons or panels while the code is showing.

Does E22 shut off the entire cooktop?

No, only the affected burner shuts down. Other burners may keep working, though we suggest having it checked soon. Any later change in scope is discussed with you and priced in writing first.
