# Bosch error code E23

### What this one means

The drain pump is blocked, jammed or has failed. 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:

- **E23, E6101** — 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:

- Debris in the pump
- A seized impeller
- A failed motor

### What to try yourself

- Bail out any standing water
- Lift the drain pump cover beside the filter and clear what is in there
- Click the cover firmly back until it seats

### Then what

A pump that hums without moving water is usually jammed rather than dead, and clearing it is the whole repair.

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.
