Bosch gives E100 a one-line description: an electronics fault. Reset at the breaker, and call if it comes back.
Model compatibility: Bosch reuses codes across series and model years, so E100 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
E100 means an electronics fault has occurred in the range.
Few entries on Bosch’s freestanding range list are as broad as E100: an electronics fault has occurred. It is written with a capital E, which is unusual for that list, and it covers the electric and the gas models.
What Bosch leaves out
No single part is tied to E100 and no cause is given, so none is offered here. Bosch’s entry holds a reset and a service step, and nothing else.
Reset
Switch the range off at the circuit breaker.
Keep it off for five minutes.
Switch the breaker on.
If the code clears and stays away, the job is done.
Reasons to book a visit
E100 returns the moment the breaker is back on.
It comes back every few days, even though the range works in between.
More codes show up alongside it.
For any of these Bosch says to contact Bosch Customer Support or arrange service. Do not open the back panel or touch the electrical connection.
Worth writing down
Since the official description is so general, your own observations count. Record when E100 appeared: on power-up, during oven heating or while the cooktop was in use. Also record whether the reset cleared it for hours, for days or not at all.
