Samsung documents it: the dishwasher turns itself on and will not turn off while it pumps the water away. That is not a malfunction, it is the machine protecting the cabinet it sits in. The sensor is in the base pan, so it finds water long before the floor does. ### The other light combinations that mean this Heavy (models without Express 60) · Normal Samsung publishes forty light combinations for the dishwasher alone, and several of them mean the same thing. They are grouped here by what they mean rather than made into forty near-identical pages, and every combination the maker names is printed above. ### Where this appears, and why not to clear it On the cycle lights, on a machine with no digital display. Samsung publishes what each combination means, and on those models the combination is the entire diagnosis — it disappears the moment the power is cut. Write it down or photograph the panel before switching anything off. Samsung adds one caution of its own and it saves service calls: on some models the lights blink to show cycle status, so treat it as an error only if the machine is misbehaving as well. ### Which machines this one applies to Models with no digital display, which report by blinking their cycle lights. Samsung itself flags that several of its codes mean two different things depending on the model — *dC*, *3E* and *BE2* on washers, and *1E* on dishwashers — so the model number is what settles which reading applies to your machine. It also publishes nothing at all for freezers, ice makers and range hoods, which is why those appliances have symptom pages here and no code pages. ### What to do about it - Let it finish draining itself; that is what it is trying to do. - Look under and behind the machine and inside the neighboring cabinet for water. - On a WaterWall machine, check the reflector is not blocked — Samsung notes it can produce the same report. - Turn the water off at the shut-off valve and have it looked at before the next cycle. ### Where this goes next The job this usually becomes is [dishwasher leak repair](/services/dishwasher-leak-repair/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
