# Bosch error code E22

### What this one means

The filter in the floor of the tub 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:

- **E22, E-22, E9240, E92-40** — 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:

- Food and grease across the filter mesh

### What to try yourself

- Twist the filter out by hand — no tools
- Rinse it under a tap with mild soap and a soft brush
- Twist it back until it seats fully

### Then what

This is the code most likely to cost you nothing. If it comes back within a month, something upstream is loading the filter faster than it should — usually a machine run only on short, cool cycles.

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.
