# Bosch error code E15

### What this one means

The sensor in the base pan has found water and shut the machine down. 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:

- **E15, E3100, F15** — the same condition, on machines of different ages
- **Active lights flashing** — how a model with no digital display says it. On that machine, the lights are the code

### 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:

- Any leak that reaches the base pan — the door seal, the sump, a hose connection, the inlet valve

### Worth doing before you call

- Turn the water off at the valve under the sink, first and before anything else
- Look for water under the front edge of the machine

### Then what

This is protection working rather than a part failing. The machine will keep refusing to run until the pan is dry and the leak is gone — and tipping it backwards to drain the pan resets the lockout without repairing anything.

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.
