Standing water at the end of a cycle on the DIN line is almost always a blockage between the filter and the drain hose rather than a dead pump. These machines put the coarse filter, the fine mesh and the pump inlet in one stack under the lower spray arm, so one obstruction stops all three at once. Two of the three likely causes are reachable without a tool.
What owners actually see
- The lower spray arm sits in water when the door is opened mid-cycle — Across the whole of this line, normal drain intervals inside a programme leave the sump nearly dry; water touching the arm between phases is early evidence of a restriction.
- The sump empties slowly rather than not at all — A partial restriction, which is the stage before a complete block and the point at which a filter clean still resolves it.
- The machine has been noticeably slower for weeks — Cycle length is the earliest drain symptom on this platform, because the programme waits for an empty sump before moving on. This applies to the whole line rather than to one model.
- NEAR MISS: water is on the floor rather than in the sump — A leak empties the tub by a route the pump does not control, and the leak page for this family covers it instead.
Ranked causes on this line
- Debris packed into the filter stack — Broken glass, labels and seeds collect in the fine mesh first and the coarse basket second. On the DIN line the whole stack sits directly over the pump inlet, so a partial block starves the pump of flow before it stops it outright. Every model in this family behaves this way.
- A kinked or trapped drain hose — On the models this family spans, the hose leaves these cabinets high and turns immediately, so pushing the machine back into a tight housing pinches it against the wall. It is the single most common cause that has nothing wrong with the appliance at all.
- An obstruction in the pump impeller — A fruit stone, a bottle cap or a shard that passed the mesh jams the impeller. The pump then hums without moving water, which is the sound owners describe as the pump running normally.
- A drain hose pushed too far into the waste spigot — An over-inserted hose restricts its own outlet, which produces a slow drain that looks exactly like a partial blockage inside the machine.
- A level sensor that never reports an empty sump — Last because it is rare and because it mimics everything above it: the pump may be emptying the tub perfectly while the control refuses to move on. Confirming it needs service tooling rather than observation.
The diagnostic order
- Bail out the standing water first — A cup and a sponge, because every later check floods the floor otherwise and because the depth tells you whether the sump emptied partially or not at all. That holds across every model this page covers.
- Unscrew and clear the whole filter stack — Second, because it costs nothing and because on the DIN line it sits over the pump inlet, so it explains both a slow drain and a stopped one.
- Look into the pump inlet with a torch — Third, once the filter is out the inlet is visible from inside the tub, so the impeller is checked without moving the machine. It is the same on all the models in the table on this page.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Assume the standing water is dirty and may hold broken glass: wear gloves for the filter stack and never sweep a hand blind around the sump.

Where the owner line is
Call once the filter stack, the impeller inlet, the hose run and the household waste are all clear and the sump still holds water. That combination points at the pump or its control, and on the DIN line the pump is reached by laying the machine over, which is a two-person job with the water services disconnected. It does not vary across the models listed on this page.
