Wolf CT Induction Code E30: burner ON LED failure, LED board

What E30 means

On earlier Wolf CT induction cooktops, such as the CT30 and CT36 sizes, E30 is one of the E30 through E34 group, which all mean a generator burner ON LED failure. The ON indicator for a burner is not working, and the official correction points to the LED board. Expect E30 on the display with some burners unavailable. Cooking itself may continue, but the indicator light for that burner cannot be trusted.

Common causes of E30

Burner ON LED not lighting or reading incorrectly
LED board failing
Connection between the LED board and the control loose

✓ One safe check you can try

1. Turn off all burners. 2. Let the glass cool, then wipe it dry. 3. Switch the breaker off for one minute and restore power. 4. Start a burner and watch whether E30 returns. 5. If it does, keep using the cooktop with extra care about which burners are on, and book a visit.

! Why to stop there

A dead indicator makes it hard to see which burner is on, which matters for safety.
LED board work happens under the glass, near live parts.

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.

E30E30 questions

What are E30 through E34?

They are the burner ON LED failure codes on the earlier CT induction cooktops. Each number refers to a different generator burner, and the LED board is the listed correction.

Is E30 dangerous?

It is not an overheating code, but a burner may be on without a working indicator. Check the surface with care and have the LED board inspected.

Will resetting power clear E30?

It can clear a one-time glitch. If E30 returns, a real LED or board problem is likely and we should look at it. If the display changes or the behavior gets worse, tell us when you call.
