Most no-drain calls on this roster end at the filter or at the waste connection, and neither needs a technician. A drain hose that has lost its high loop siphons the machine empty and then lets the sink's water back in. Only a pump replacement takes this off the owner list on this platform. Read the rating plate rather than the badge on the door — the badge is a line name and the plate is the listing.
What owners report
- Dirty water appears in the tub between cycles — Backflow from the sink waste, which means the drain hose has lost its high loop or its air gap.
- A gurgling from the sink when the machine drains — The waste is shared and partly restricted, so the machine and the sink are fighting for the same pipe.
- A smell that gets worse between uses — Standing water in the sump with food in it. The smell is a symptom of the drainage fault, not a separate problem.
- NEAR MISS — the machine never filled in the first place — An empty tub with a stopped cycle is a fill fault, not a drain fault, and it belongs on a different page.
Causes, most likely first on this roster
- Filter and sump packed with debris — First on this roster. The filter is the last line before the pump and it catches everything: labels, seeds, fragments of bone. When it fills, the water stops before it ever reaches the pump.
- Drain hose kinked or without a high loop — Installation faults rather than failures. A crushed hose restricts; a hose with no rise lets the sink drain back into the tub.
- Check valve stuck — The valve that stops drained water returning can stick open or closed. Open, the tub refills from the hose; closed, nothing leaves at all.
- Drain pump failed — Last. A pump that is silent when the machine calls for drain is either dead or not being told to run, and separating those two needs a meter rather than a torch.
- Body: Ranked for these models. The top of this list is maintenance and the bottom is a component, which is the usual shape for a drainage complaint on this class of machine.
What to check first, second, third
- Bail out the standing water and remove the filter — It gives you access to everything else and the filter itself is the commonest answer on the page.
- Reach into the sump and clear what is in it — Carefully, because glass ends up here. A foreign object against the impeller is found at this step, not later.
- Body: Listen first, then look. Whether the pump runs at all decides which half of the list you are working through.
Safety before diagnosis
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Water on the floor in front of a machine you are about to slide out is a slip hazard first and a drainage problem second. Dry it before moving anything heavy. This family resolves to one listing, which makes the page unusually definite about what it covers.
Models in the DSD family — A family page rather than a model page. The rows below are what it generalizes over, and the generalization ends there.

When this stops being owner work
Clear what you can see and reach. Call when the machine hums and will not move water after the sump has been cleared, because that means the obstruction is inside the pump housing, which does not open from the tub side on this platform. Everything upstream of that is owner work on this roster.
