The short answer for Asko D
For the models listed under Asko D, water left standing at the end of the cycle is most often a blocked air gap at the sink. The generic article for this brand puts the emphasis elsewhere; the roster below is why this page does not. Of the five causes ranked below, four are owner work and the remainder need a technician.
What you observe on these models
- The machine stops with a fault part-way through and the tub is full — The control has detected water it cannot remove, which at least confirms the sensing works.
- The machine drains fully only when the sink is empty — A shared drain that cannot take both, which is plumbing rather than appliance.
- Water appears in the sump after the sink is used
- A smell of stale water when the door is opened
- The machine gurgles at the sink and drains slowly
- NEAR MISS — water on the floor rather than in the tub — A leak has its own page. Here the water is exactly where it was put and will not leave.
Causes, most likely first on Asko D
- A blocked air gap at the sink — Where an air gap is fitted on the countertop, it collects debris and blocks, and the machine then pushes water out of its cap instead of down the drain. It earns this place because the cap lifts off and the insert cleans out with a brush in a few minutes.
- A blocked filter, sump or drain grate — Placed at this point because it is the commonest single cause of a machine that will not empty, and it is the part designed to be cleaned by the owner.
- A disposal knockout plug left in, or a blocked disposal — It is here because a disposal full of waste blocks the shared path just as effectively as a plug, and running it empty settles the question.
- A kinked drain hose or a missing high loop — Ranked here because it is corrected without parts once the machine is drawn out.
- The drain pump wiring, the control board or the drain valve — A control that never energises the pump, or a drain solenoid that will not open, on a machine whose filter, hose and air gap are all clear. It sits at this point because it is reached last because every cause above it leaves the same standing water for far less money.
Check in this order, and why
- Lift the air gap cap on the countertop and look inside — Debris in the air gap explains both poor drainage and water appearing on the counter, and it needs no tools to clear.
- Lift the filter out and look at the drain grate underneath — Debris across the grate explains standing water immediately, and clearing it is usually the whole repair.
- Run the disposal empty and check whether the knockout was ever removed
- Follow the drain hose from the machine to the sink connection
- Why this order and not another — It follows the ranking, not a generic checklist: on Asko D the first check separates a blocked air gap at the sink from a blocked filter, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.
Safe access on a built-in machine
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Kill the breaker, not just the cycle, and close the hot supply stop under the sink before anything comes loose.

When to call a technician
Stop and call once every accessible part of the drain path is proven clear and the tub still holds water. Note whether the pump makes any sound at the drain step before you call — a silent pump and a loud one point at completely different repairs, and saying which saves a visit.
