About Bosch error code ERR toP
What this one means
A cooking zone was switched on while a self-clean cycle was running. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
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.
