What this usually is on these models
Standing water in the bottom of the Almison ASDW dishwasher after a cycle is usually something in the drain path rather than a failed pump. The codes in this family carry a wildcard block the record does not expand, so two machines can share the code printed here and still differ in trim. The order below works from the filter outwards, because each step in turn puts the water further from the machine and closer to the house plumbing.
What the owner actually sees
- Water standing in the bottom at the end of every cycle — Clean or dirty, it makes no difference to the diagnosis — the machine finished and the water did not leave.
- Dishes come out gritty or filmed — Water that is not leaving is water that gets re-used, and it carries the last load's soil with it.
- A hum at the drain step with nothing moving — The pump is being asked and cannot turn, which usually means something hard has reached the impeller.
- NEAR MISS — it never filled in the first place — An empty tub with clean dishes is a fill or start fault, and it belongs on a different page from this one.
What it usually turns out to be, in order
- The drain hose: kinked, crushed or run without a high loop — First. A drain hose has to rise before it falls, or the machine siphons its own water back. Push a machine into a tight space and the hose gets flattened against the wall behind it, which is why this fault so often dates from the day the kitchen was fitted. The same check covers everything from ASDW12F**A5A to ASDW12T**A5A; the record gives no reason to treat those codes differently here.
- The filter and sump, packed with what came off the dishes — Second. Everything the wash water carries ends up at the filter, and a filter that has not been lifted out in months stops passing water long before it looks blocked. This is the first check on any machine that will not drain, and on most of them it is also the last.
- A waste disposer knockout plug that was never removed — Last. Where the drain is connected into a disposer, that connection is sealed at the factory with a plug that has to be knocked out at installation. Miss it, and the machine fills, washes and then has nowhere to send the water — a brand-new installation that has never drained once.
- Body: Two codes stand behind this page, each with a block the record leaves unexpanded. The drain path outside the machine is the part that gets disturbed every time the machine is pulled out, and it is checked before anything inside is opened because correcting it costs nothing.
Check in this order, and why
- Trace the hose behind the machine — It should be free of kinks, not crushed against anything, and it should rise before it reaches the waste. Both faults are corrected by hand, with nothing dismantled. Identical on every code from ASDW12F**A5A to ASDW12T**A5A.
- Lift the filter out and look underneath it — Take the coarse filter and the fine screen out together, rinse them, and clear the sump by hand. Anything hard in there — glass, a stone from a jar lid, a fruit pit — is on its way to the pump.
- Body: Work these in order rather than picking the one that sounds most likely. Each check below removes a whole branch of the list above, and none of them needs a panel off or a tool in hand.
Safety first
Safety
Switch the machine off at the breaker before putting a hand into the sump — a capacitor can hold a charge after the power is off. Assume there is broken glass in any standing water and bail it out with a cup and a cloth rather than scooping it. If the water is hot, let it cool before you start; a dishwasher drains water hot enough to scald.

When to call a technician
The filter, the hose run and the interrupted-cycle question are all owner work, and together they settle most of these. Call when the sump is clear, the hose is sound and the pump still hums or stays silent at the drain step, because from there the job needs the machine tipped and opened. Call the plumbing side instead, not the appliance side, when water rises at the sink air gap during a cycle: that is a blocked waste line and the Almison ASDW machine is not at fault.
