# 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](https://esbosch.djwp.xyz/error-codes/) has the rest.
