What it looks like from the kitchen

## The symptom this code usually arrives with

A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

- Dishwasher leaking
					Water on the floor, or a machine that will not start and shows E15. The lockout is a protection working rather than a failure, and it clears once the pan is dry and the cause is found.

														E15 and the anti-flood lockout

														A damp patch at the front of the cabinetry

														A machine that runs, then stops mid-cycle

## About Thermador dishwasher error code E15

### What this one means

The float in the base pan has lifted and the leak protection has taken over. 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** — 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:

- A real leak anywhere above the pan
- A door seal letting water past
- Condensate that has found the pan instead of the tub

### Worth doing before you call

- Turn the water off at the shut-off valve under the sink before anything else

### Then what

The machine has already made itself safe. Finding where the water came from is the repair; drying the pan is not.

This code is published for dishwashers. The [full list of codes](https://thermadormiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
