Not Draining
Standing water at the end of a cycle points to the drain path. Clean the triple filter at the base of the tub first, then check the drain hose for kinks and the sink air gap or disposal port if the machine drains through the sink. Debris caught in the drain pump can also stop it. Clearing the filter and hose resolves many drain complaints; a failed pump needs replacement.
Not Filling
If the machine will not take water, check that the supply valve under the sink is open and the inlet hose is not kinked. Miele inlet hoses include a safety valve that can trip. If the supply is fine and it still will not fill, the inlet valve or its wiring is the likely fault.
Poor Drying
Miele dries with residual heat and rinse aid rather than a hot fan blast, so low rinse aid, an overloaded rack, or plastic items that shed water poorly are common reasons dishes come out damp. Top up rinse aid and load with space between items. If the water is not heating at all, that is a heating-circuit fault and needs service.
Leaks
A leak can come from the door gasket, a hose or pump connection, or the tub itself. Miele units include an anti-flood system with a float in the base that shuts the machine down when it senses water. Shut off the water supply and book a diagnosis so the source is found before it damages cabinetry or flooring.
