# Bosch error code E:00  -18

### What this one means

The pump is obstructed.

### 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 pump unit
- The drain hose
- The drain pipe

### What to try yourself

- Clean the drain hose and the pipe it goes into
- Open the pump filter at the bottom front and clear it

### Then what

Same family as the other drain codes and the same list of causes. Which number a machine shows depends on its generation rather than on what is wrong.

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