-
After a self-clean cycle Oven door locked shut
A door that locked for self-clean and has not released. Most of them open once the cavity is genuinely cold — and the ones that do not have a published code of their own, which tells you how often this happens.
- Locked since a self-clean cycle
- Lock icon showing with the oven cold
- A grinding noise from the lock

What else belongs to the ranges

About Bosch error code ERR toP
What this one means
A cooking zone was switched on while a self-clean cycle was running.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- A zone left on when the cycle started
What to try yourself
- Turn off every active cooking zone
- Start the self-clean function again
Then what
The appliance refusing to run its hottest cycle with the surface above it also heating. Sensible, and cleared by turning the zone off rather than by any repair.
This code is published for ranges. The full list of codes has the rest.
