Of all the calls about the SHE2ADF6N, the black-door 100 Series front-control model, the commonest is not a breakdown. Its keys are printed on a dark background, and in a dim kitchen owners squint, can read nothing, and conclude a button has died.
A key can still truly fail. When it does, the culprit is the membrane behind the fascia and not the main board, so the work happens at the door panel and never at the bottom of the machine. Testing every key is our first move.
Underneath, it is a 12-place-setting, 52 dBA machine whose flow-through heater is built into the circulation pump housing. That layout explains E09 here: the pump and heater are a single assembly, with no separate element to swap out. Cloudiness on glasses in hard-water homes usually means the rinse aid reservoir ran dry, which is a refill and not a repair. Home Connect lets owners keep an eye on the machine remotely.
Probably not. A dead key normally means the touch membrane inside the door fascia has worn out. That sheet is sold separately from the main control board beneath it.
Water chemistry is the likely reason, not a failing machine. Look at the rinse aid reservoir first. Households with hard water can also ask us how the built-in softener is set during a visit.
E09 is a heating problem. Since the heater sits inside the circulation pump housing on this platform, the repair usually means replacing that pump-and-heater assembly as one unit, not a loose element.
