# Bosch error code E:36 -25 -26

### What this one means

The drain pump is blocked. 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:

- **E:36 -25 -26, E:38 / -25 / -26** — 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 pump filter
- The impeller behind it

### What to try yourself

- Unplug the machine
- Open the flap at the bottom front and let the water out through the spout
- Unscrew the filter and clear it, then check the impeller turns freely

### Then what

The filter behind that flap is meant to be opened by the owner every few months, and almost nobody knows it is there. Coins, hair grips and lint are what usually come out.

This code is published for washers. 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.
