The short answer for Asko DOD
For the models listed under Asko DOD, water left standing at the end of the cycle is most often a blocked filter, sump or drain grate. The generic article for this brand puts the emphasis elsewhere; the roster below is why this page does not. Four of the five causes below are owner-checkable with nothing but hand tools; the rest are a service call.
What you observe on these models
- The machine gurgles at the sink and drains slowly — That points at the air gap, the disposal connection or the house drain rather than the machine.
- Water appears in the sump after the sink is used — Backflow from the shared drain, which is an installation fault rather than a pump fault.
- The machine stops with a fault part-way through and the tub is full
- The pump runs loudly at the drain step and nothing leaves
- Dishes come out dirty as well as wet
- 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 DOD
- A blocked filter, sump or drain grate — The debris the filter catches has to be removed by hand. Left, it mats across the filter and closes the drain path below it. It sits 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 kinked drain hose or a missing high loop — It earns this place because the hose gets crushed whenever the machine is pushed back under the counter, so the fault often starts after other work.
- A blocked air gap at the sink — Placed at this point because the cap lifts off and the insert cleans out with a brush in a few minutes.
- A disposal knockout plug left in, or a blocked disposal — It is here because it is the standard explanation for a machine that has never drained since it was fitted, and it is fixed in minutes.
- 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. Ranked here because a pump that never runs at all, with a clean filter and a clear hose, has narrowed the fault to the circuit that drives it.
Check in this order, and why
- 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.
- Follow the drain hose from the machine to the sink connection — Any crush, and any run that does not rise above the machine before it falls, explains the standing water.
- Why this order and not another — It follows the ranking, not a generic checklist: on Asko DOD the first check separates a blocked filter from a kinked drain hose or a missing high loop, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.
Before you pull the machine out
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A built-in dishwasher is usually fed from a junction box under the cabinet rather than a visible plug, so the breaker is the isolation point and it is worth confirming at the panel rather than assuming.

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.
