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.
-
The machine stops itself 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.
