Answer first
On a White-Westinghouse dishwasher standing water is usually the filter and sump packed with debris, not a failed pump. The pump is the part people replace and the part that is least often at fault. Bail the water out first: it makes every check below faster and it stops the smell.
What you actually observe
- Drain water backs up into the sink or the sink backs up into the machine — That is the shared waste, not the appliance.
- NEAR MISS: water is on the floor rather than in the machine — Read the water-leak page instead.
What it usually turns out to be, in order
- The filter and sump packed with debris — Everything the machine washes off ends up here. Packed with soil, labels and broken glass, the filter stops water reaching the pump at all. Ranked first on this unit: it is the first restriction in the path, it is reachable without a tool, and on most machines it has never been cleaned, which counts for more here because this is a nameplate with a large installed base, which means most units still working are well past their first decade and fail by wear rather than by design.
- A kinked, crushed or badly routed drain hose — The hose behind the machine gets crushed when the unit is pushed back into its housing, or it is left without the high loop that stops water siphoning back. Second: it is disturbed every single time the machine is pulled out or pushed back, which is exactly what happens before this fault appears.
- A failed drain pump or a stuck check valve — A dead pump makes no noise at all at the drain phase, and a check valve stuck shut gives the same standing water with the pump running normally. Bottom of the list, deliberately: everything above it leaves the same water in the sump and costs nothing to rule out.
The order to check in
- Twist out the filter and look into the sump beneath it — A packed filter explains both a slow drain and a total one.
- Pull the machine out and follow the drain hose to the waste — A kink or a crush is visible immediately, and a missing high loop just as much.
- Only once the filter, the hose, the air gap and the waste are all clear — Silence at the drain phase after all that is a parts job.
What an owner can safely check
- Bail out the standing water, twist out the filter assembly and clear the sump by hand — Wash the filter under a hot tap and refit it locked home.
Tools: a cup, a cloth, a brushAbout 25 min
- Pull the machine forward and check the drain hose is not kinked, crushed or lying flat all the way to the waste — It needs a high loop, and it must not sit in standing water at the other end.
Tools: a torchAbout 20 min
- STOP AT THIS POINT if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Read this before you touch it
Safety
Kill the power at the breaker, or unplug the machine, before a panel comes off, and close the supply valve under the sink before you touch a hose. The element in the sump holds heat long after a cycle ends, so give it time before you reach in. Never run the machine with its kick plate off, and never wedge a door latch to make a cycle start.
The line between a fix and a service call
Call once the filter, the drain hose, the air gap and the household waste are all clear and the machine still holds water, because at that point the pump or its valve is the fault. Call sooner if the machine trips a breaker, if water is reaching the floor, or if you find glass you cannot safely remove.

What this page does not cover
This page covers the White-Westinghouse dishwasher as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: pump part numbers, check valve procedures and any wiring detail, all of which differ by family and belong on the page for that family.
