# Bosch error code E10

### What this one means

The heater in the mineral drying chamber is not responding. 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.

### 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:

- **E10, E2120** — the same condition, on machines of different ages

### 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 chamber heater
- Its circuit

### Worth doing before you call

- Check whether the glassware is still coming out dry — if it is, the wash side is healthy and this is drying alone

### Then what

This is on the upper series only. The machine still washes perfectly; it simply loses the drying advantage those models were bought for.

This code is published for dishwashers. 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.
