# Bosch error code F8

### What this one means

A zone was left running without any control being touched, and the automatic time limit switched it off.

### The other ways your machine may say it

The same condition is published under more than one label, because it has been carried across generations of this appliance:

- **F8 with H or h and the zones not heating** — how a model with no digital display says it. On that machine, the lights are the code

### 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:

- The safety timer

### What to try yourself

- Touch any control on the surface
- Set the zone again and carry on

### Then what

A deliberate safety feature rather than a problem, and the time allowed is longer at low power than at high. It exists because a hob left on and forgotten is one of the more dangerous things in a kitchen.

This code is published for cooktops & rangetops and ranges. [The full list of codes](https://esbosch.djwp.xyz/error-codes/) has the rest.
