The short answer for Asko DSD
Water left standing at the end of the cycle on an Asko DSD dishwasher is a disposal knockout plug left in, or a blocked disposal more often than it is the drain pump wiring, the control board or the drain valve. What moves it is the platform rather than the brand. Of the four causes ranked below, three are owner work and the remainder need a technician.
What you observe on these models
- The pump runs loudly at the drain step and nothing leaves — A pump working against a blockage is louder than a healthy one, not quieter.
- A smell of stale water when the door is opened — Water that has been standing between cycles, which is the same fault seen from a different sense.
- NEAR MISS — a small pool in the sump that has always been there — Many machines keep a little water in the sump to stop the seal drying. Covered filter is a fault; damp sump is not.
Causes, most likely first on Asko DSD
- A disposal knockout plug left in, or a blocked disposal — Where the drain hose connects to a food waste disposal, a moulded plug has to be knocked out at installation. Left in, the machine can never drain at all. It earns this place 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 — The hose has to rise before it falls, or the sink drains back into the machine; and a hose crushed behind the cabinet cannot pass water at all. Placed at this point because it is corrected without parts once the machine is drawn out.
- A blocked air gap at the sink — It is here because it gives a very visible symptom — water or debris coming out of the cap on the countertop — that belongs to nothing else.
- 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
- Run the disposal empty and check whether the knockout was ever removed — A machine that has never drained properly since installation is a knockout plug until proved otherwise.
- 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 DSD the first check separates a disposal knockout plug left in 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.
Isolate the power and the hot feed
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Most built-in dishwashers are hard-wired, so switch the breaker off and check that the panel really is dead before you reach behind the toe kick. Close the hot water stop under the sink.

When to call a technician
Call when the filter and the grate are clear, the disposal runs with its knockout out, the air gap is clean and the hose has a high loop with no crush — and the tub still holds water. Say whether the pump makes any sound at the drain step, because a silent pump and a loud one lead to completely different repairs.
