The short answer for these models
Standing water in the bottom of the ADWW line is nearly always a blockage between the sump and the sink waste rather than a failed pump. This family is one model number, which makes the scope of this page unusually clear. The blockage is usually somewhere an owner can reach, which is why the ranking below starts inside the machine and works outwards.
The observations that separate this fault from its neighbours
- A hum at the end of the cycle with no water moving — The pump is being asked to run and cannot. Either it is jammed, or what it is pumping into is blocked.
- Water in the tub smells stale between cycles — Water that sits is water that was not pumped out, so a smell often arrives before the standing water is noticed.
- The machine drains slowly but does get there eventually — A partial restriction. It will become a complete one, so treat a slow drain as an early warning rather than a quirk.
- Glass, seeds or a paper label in the filter area — Debris that gets past the filter reaches the pump, and a fragment in the impeller stops drainage entirely.
- NEAR MISS — no water at all and nothing happened — That is a fill or a start fault, and the will-not-start page for this family is the right one.
What to suspect, in order, on this family
- A filter that has stopped passing water — First on the ADWW line. Everything the machine washes off ends up here, and when the filter mats over, water cannot reach the drain pump at all. It is the most common cause of standing water and the only one that needs nothing but a rinse under a tap.
- Something jammed in the pump — Second, and it follows directly from the first: a filter that has been out of place is how debris reaches the pump in the first place.
- Drain hose kinked or wrongly routed — Third. A hose crushed behind the machine after it was pushed back, or one that has lost its high loop, both stop the drain without a single part failing. Worth checking whenever the machine has been moved.
- Sink waste, disposer or air gap blocked — Fourth, and the first thing to check if the sink itself is also draining slowly — one blockage, two symptoms.
- The pump itself, or the signal to it — Last. A pump that is electrically dead is silent rather than humming, and it is the only item here that needs a meter and the machine opened.
The order to work in on these models
- Bail the standing water out first — Nothing below can be seen or reached through a tub full of water, and the water may still be hot.
- Lift the filter out and look at it — The most common cause, found in under a minute, and it also exposes the sump.
- Check the sump well for glass, seeds and labels — Scoop rather than grope — broken glass in a sump is the usual injury on this job.
- Pull the machine forward and look at the hose — Kinks, crushing and a lost high loop are all visible without disconnecting anything.
- Check the sink waste and the disposer connection last — Last unless the plumbing has recently been worked on, in which case it is first.
Before you open anything
Safety
Switch the dishwasher off at its breaker or unplug it before any panel comes off — a capacitor can hold a charge after the power is off, and the machine sits in a wet space where that matters more than usual. Sharp edges sit under the lower rack and inside the sump on machines of this build, and the heating element stays hot for some time after the cycle ends.

When to call a technician
Call once the free checks are clean. Tell the technician three things: whether the pump hums, whether the sink drains, and what came out of the filter. On the ADWW line those answers usually decide whether the visit is a pump job or a plumbing one before anybody opens the machine.
