Bosch cooktop demo mode (dE) error
- Cooktop
Bosch cooktop DEMOC (shown as dE on the display) means Demo Mode is active — the touch controls respond but heating zones stay off. This often happens after showroom display or an accidental key sequence on NIT8060 and similar induction cooktops. A breaker reset plus the demo exit sequence restores normal heating.

No safety issue
This is a status or lock code, not a hardware fault.
How to fix DEMOC
- Turn off power at the breaker for 60 seconds, then restore power.
- Within 30 seconds of power-up, touch and hold the key combination from your manual to exit demo (often a timer + power pad).
- Confirm dE is gone and place induction-compatible cookware centered on a zone — demo off should allow heating.
- If dE returns after every power cycle, check whether Sabbath or lock modes are also enabled.
- Persistent dE with no heat after the exit sequence may need service — but try demo exit twice before calling.
Call a pro when: Call a technician if zones still will not heat after demo is cleared and cookware is induction-ready.
