The short answer for this family
On the Almison ASDW family, a dishwasher left with water in the bottom is usually a loaded filter at the tub floor. A compact tub concentrates everything the filter catches into a small sump, so the filter and the drain path outrank the pump on this family. The brand-generic order holds at the head here; what this platform changes is the order below it. The checks at the head of the ranking cost nothing but time; the cause at its foot is not owner work at any stage.
What you observe on these models
- Which of the family's models you are standing in front of — The matrix on this page is two builds of one machine, separated by a single letter in the model number, and that is worth reading first, because a compact tub concentrates everything the filter catches into a small sump, so the filter and the drain path outrank the pump on this family.
- Standing water in the well at the end of the cycle — The machine has finished and the water has not left.
- The pump is audible and nothing happens — A pump that runs and moves nothing is obstructed rather than failed.
- It drains slowly and finishes eventually — A partial restriction, and it becomes a complete one.
Causes, most likely first on the ASDW family
- A loaded filter at the tub floor — Ranked first because a compact tub concentrates everything the filter catches into a small sump, so the filter and the drain path outrank the pump on this family.
- The drain pump and its impeller — Second. The filter lifts out of the tub floor; the pump and drain hose are under the machine, so the pump sits directly under the filter and is reached the same way.
- The drain hose, its loop and the disposer connection — Third. Look at the high loop and at where the hose joins the waste: both faults date from the last installation.
- How the machine is loaded — Fourth. Free to test and it rules out a whole class of complaint.
- The door catch and its switch — Last. Check the catch before anything is dismantled.
- Body: This is not the brand-generic ranking. The head of the ranking matches the brand-generic order, but below it the drain pump and its impeller moves up to second place, because the platform here is a compact machine with one wash pump, a filter at the sump and a short drain run.
Check in this order on these models
- Lift the filter and clear the well underneath — Bail the standing water out first with a cup and a sponge. What is under the filter is usually the whole answer.
- Listen during the drain phase — A pump grinding or rattling has something hard in it, and glass fragments are the usual passenger.
- Check the drain hose loop and the waste connection — Look for the high loop behind the machine, and at the disposer or waste spigot: a plug left in at installation stops the drain permanently.
- Check nothing has fallen into the well — A label, a piece of foil or a bone in the sump blocks the drain without ever looking like a fault.
- Body: The order follows the ranking, and the access decides the rest: on these models the filter lifts out of the tub floor; the pump and drain hose are under the machine.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before reaching into the sump or opening any panel; a capacitor can hold a charge after the power is off. Wear gloves when feeling round the well: broken glass collects there and it cannot be seen under water.

Where the owner limit falls on these models
Call when the filter and the sump are clear, the hose is unkinked with its loop in place, the waste connection is open and the machine still holds water. Call promptly if the pump grinds: a pump run against glass wears its impeller, and it will not recover once the obstruction is out.
