Wolf Induction Cooktop Code E45: open burner sensor or LIN hardware error

What E45 means

E45 appears on two Wolf induction platforms and means different things. On earlier CT induction cooktops such as the CT30I/S and CT36I/S, it means a generator burner sensor reads open. On the newer touchscreen CI cooktops, for example the CI30460T/S and CI36560C/B, it reports a LIN hardware error, a problem with the internal communication link. Owners see E45 and reduced or no heating.

Common causes of E45

CT models: open generator burner sensor circuit
Touchscreen CI models: internal LIN communication hardware error
Loose connection or a failing control board

✓ One safe check you can try

1. Turn all zones off and let the surface cool. 2. Turn the cooktop's circuit breaker off for one minute, then reset it. 3. Wipe the glass and touch area dry. 4. If E45 returns, note which model line you have and call us. Do not remove the glass or open any panel.

! Why to stop there

The two platforms use different parts, so the fix depends on which one you own.
Communication and sensor circuits need testing with the unit isolated.
You get a written quote first.
Our repair includes 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.

E45E45 questions

How do I know which meaning applies to my cooktop?

Older CT30I/S and CT36I/S units follow the sensor meaning, while newer CI30460T/S and CI36560T/S touchscreen models follow the LIN meaning. The model number printed on your cooktop's data label settles which one you have.

Will a reset help?

A single breaker reset can clear a momentary communication hiccup. If E45 returns right away, a sensor or board needs inspection and repeated resets will not help.

Is E45 urgent?

It is not a safety alarm, but the cooktop may be unreliable. We recommend scheduling a visit rather than waiting for a complete loss of heating.
