What this means on this family
Standing water in the bottom of the ADWSS family is nearly always a blockage between the sump and the sink waste rather than a failed pump. The table on this page carries a single model number, so everything here describes one build. 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
- 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.
- 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.
- Drainage failed right after new plumbing or a new disposer — The single most informative symptom on this page: a disposer knockout plug left in place blocks the drain completely.
- NEAR MISS — water on the floor rather than in the tub — That is a leak and belongs on the water-leak page for this family.
What to suspect, in order, on this family
- Disposer knockout plug or a blocked waste — Ranked first because the timing gives it away: drainage that stopped the week the sink was worked on is almost never a coincidence.
- Drain hose routing and the high loop — Second. Without a high loop or an air gap, waste water siphons back into the tub, and a hose crushed against the wall stops the drain outright. Both are found by pulling the machine forward and looking.
- Filter and sump — Third. The standard internal cause, ranked below the plumbing here because on this family the external path has to be cleared first — otherwise a clean filter gets blamed for a blocked waste.
- Pump impeller obstruction — Fourth. Reached once the path outside and the filter inside are both clear, and identified by a hum that produces no movement.
- Drain pump failure — Last. Silence rather than a hum is the pattern that points here.
What to check first, and why that order
- Ask what changed in the kitchen recently — New disposer, new waste, machine moved — the answer often ends the diagnosis before any panel is touched.
- Run the sink tap and watch it drain — A slow sink makes the shared waste the suspect, and no work inside the machine will fix that.
- Inspect the drain hose route and its loop — Done before opening the machine because it needs nothing but pulling the appliance forward.
- Clear the filter and the sump — Now worth doing, and it is the fix if the outside path is clear.
- Listen for the pump at the drain phase — A hum means an obstruction; silence means the pump is not being driven at all.
Safety first
Safety
Power off at the breaker before the kick panel or the door panel is removed, and water off before any connection is opened. 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.

The line between an owner fix and a service call
The boundary here is the kick panel and the meter. Bailing the tub, clearing the filter, checking the impeller and fixing hose routing are all owner-side, and they resolve most of these complaints. A silent pump, a suspected control fault or a waste that needs re-plumbing is a service call — and the plumbing half may be a plumber rather than an appliance technician.
