# Bosch dryer error code E01

### What this one means

The lint filter is blocked and needs cleaning. 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:

- **E01, E02 dryer** — 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 lint filter
- The fluff filter behind it

### What to try yourself

- Clean the lint filter after every cycle
- Hold it under a running tap — if water pools on the mesh instead of passing through, it is sealed with fabric softener film
- Rinse the fluff filter with warm water occasionally

### Then what

The most useful thing on this page is the water test. A filter can look perfectly clean and pass almost no air, because the film that seals it is transparent. Scrubbing it with warm soapy water is free and it is the single most common fix on the appliance.

This code is published for dryers. 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.
