Wolf Module Cooktop Code E24: Cap-Touch keypad micro internal error

What E24 means

On Wolf integrated module cooktops from the 2015 series, such as the CE152TF/S and GM15TF/S, E24 means the cap-touch keypad micro has an internal error. The microcontroller behind the capacitive touch panel stopped working correctly, so the keypad may not respond or may act on its own. The display shows E24, and the module cooktop may refuse to heat until the keypad control is serviced.

Common causes of E24

Microcontroller behind the cap-touch keypad failing
Keypad board that needs replacing
Power disturbance that confused the keypad micro

✓ One safe check you can try

1. Turn off all modules. 2. Wipe the glass dry, as moisture can confuse touch panels, and remove items from the controls. 3. Wait one minute with the breaker off, then restore power to the cooktop. 4. If E24 shows again, stop and call us; the keypad is part of the glass assembly.

! Why to stop there

The keypad micro is inside the control assembly, which owners should not open.
A touch panel that misbehaves can start a burner by accident, so we want it checked.
Our technician writes up the price before work, and the repair is covered for 30 days.

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.

E24E24 questions

Could moisture cause E24?

Water on a touch panel can cause odd behavior, so drying the glass is a good first step. E24 itself, though, names an internal micro error.

Is E24 related to E15?

E15 is a communication link problem with the cap-touch, while E24 is an internal error in the keypad micro itself, so the fix points to the keypad board.

Why not keep using the cooktop?

If the keypad is unreliable, it might not turn burners off when you ask. We suggest leaving it off at the breaker until we inspect it.
