Demo mode is on, which keeps the cooking zones cold. Bosch's cure: breaker off for 30 seconds, then a touch within 3 minutes.
Model compatibility: Bosch reuses codes across series and model years, so dE may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Demo mode has been switched on, and the cooking zones will not heat.
When a Bosch induction slide-in range shows dE and its cooking zones stay cold, demo mode is switched on. Bosch lists dE in the induction section of its slide-in range page with exactly this meaning.
Cancelling demo mode
Go to the electrical panel and turn the breaker or fuse that feeds the range off, counting 30 seconds.
Turn it back on.
Press any control on the range before 3 minutes are up.
The final touch has to land inside that 3-minute window, so remain near the range once power is back.
Handy notes
Problem
Answer
No label on the breaker
Look for the breaker marked for the range or oven, or have an electrician mark the panel.
3 minutes passed before touching
Turn the power off for another 30 seconds and go through the steps again.
dE stays on
Past this, Bosch lists nothing else an owner can do. If the range is still in demo mode after a correct power cut and touch, it is time for service.
