# Bosch error code E9011

### What this one means

The appliance is not connected the way its wiring diagram requires. 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:

- The connection at the appliance
- A bridge or link left in or out

### Worth doing before you call

- Note whether this appeared straight after installation or after electrical work

### Then what

Almost always an installation code rather than a failure. These cooktops can be wired several ways depending on the supply, and getting it wrong produces an appliance that powers up and refuses to cook.

This code is published for cooktops & rangetops and ranges. The [full list of codes](https://boschmiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
