Bosch Oven Error Code E000
E000 means the oven's two main electronic boards do not match: the control module and the user interface disagree about what appliance they are fitted to, so no operation is possible. It almost always follows a board replacement where the model's option code was never set.
Common causes
- Control module and user interface are mismatched after a board replacement
- Option code never set after a control or display board was changed
- Wrong replacement board fitted for the model
What to check, in order
- Note the code: E000 normally appears at start-up right after board-level service, not during cooking.
- Reset the oven at the breaker for a minute; if E000 returns at every start-up, the boards still do not recognise each other.
- The option code is set in service mode from a label inside the top of the oven; entering service mode and option codes is technician work because the oven must be pulled out and opened.
- Book the technician who replaced the board if the code followed a repair — setting the option code is part of completing that job.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
This code usually points to a faulty part, wiring or the control board on a Bosch oven. Run the checks above to rule out the simple causes, then book a technician — and book one straight away if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E000, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Repair or replace?
This fault is in professional territory: the fix usually means a major part or board-level work, and the labour adds up. If your machine is already well into its service life, get the repair quote first, then compare it with the price of a current equivalent model before you decide. Paying a large share of a new machine's price to repair an old one is rarely the better deal; replacing a machine over one cheap fault is wasteful too.
Parts that may be involved

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
