The short answer
Standing water at the end of a programme on the DIS line is a flow problem with a short list of suspects, and the list is ordered by how easy each one is to reach. The filter stack lifts out by hand, the hose is behind the cabinet, and the pump is under the tub. Work outward from the tub and you will usually stop before the third.
What you observe
- Water is standing in the sump when the cycle ends — For every model in this family, enough to cover the filter plate and sometimes the bottom of the lower rack, and it does not fall away when the door is opened.
- A previous load included something that broke — A glass or a china item that shattered puts fragments straight into the filter stack and the pump inlet.
- The problem began after the kitchen was rearranged — Pushing the cabinet back is what pinches the drain hose, so a fault dated to a move is a routing fault until proven otherwise. It does not vary across the models listed on this page.
- NEAR MISS: the tub is dry but the load is wet and dirty — That is a wash or fill fault, not a drain fault, and it belongs on the cleaning-performance page for this family.
Causes, most likely first
- Debris packed into the filter stack — Broken glass, labels and seeds collect in the fine mesh first and the coarse basket second. On the DIS line the whole stack sits directly over the pump inlet, so a partial block starves the pump of flow before it stops it outright. This applies to the whole line rather than to one model.
- A kinked or trapped drain hose — On each of the models covered here, 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.
- A blocked waste connection or standpipe — The machine drains into shared household waste, so a partly blocked sink trap or a plugged spigot on a disposer stops the appliance even though the appliance is fine.
- A drain hose routed without a high loop — Without the loop the sump siphons back and the machine appears to refill itself, which reads as a drain failure when it is a routing one.
- A failed drain pump or its control — Genuinely last on this platform. The pump is a sealed motorised unit and every cheaper cause imitates it, so replacing it before the filter stack and the hose have been cleared is the most common wasted repair on these machines.
Check in this order, and why
- 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. The models in the table behave the same way here.
- Unscrew and clear the whole filter stack — Second, because it costs nothing and because on the DIS 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. That is true of every model this family spans.
Before you begin
Safety
Switch the appliance off at the breaker before anything is dismantled. A capacitor can hold a charge after the power is off. Treat every sump as if it contains glass, because the households that report drain faults are disproportionately the ones that broke something.

When to call a technician
Call when the filter stack, the impeller inlet, the hose insertion depth and the household waste are all proven and the sump still holds water at the end of a drain-only programme. That is the point at which the pump is the remaining explanation. That holds across every model this page covers.
