The short answer for Asko DFI
The Asko DFI family answers this differently from the brand as a whole: here a blocked filter, sump or drain grate ranks ahead of the drain pump wiring, the control board or the drain valve, because of how these models are built and how they are reached. Of the four causes ranked below, three are owner work and the remainder need a technician.
What you observe on these models
- Standing water in the sump at the end of every cycle — A little water in the sump is normal on some machines; a covered filter is not.
- The machine drains fully only when the sink is empty — A shared drain that cannot take both, which is plumbing rather than appliance.
- 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 DFI
- 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. Ranked here because it lifts out by hand and clears under a hot tap in minutes.
- A kinked drain hose or a missing high loop — It sits at this point because it explains water that appears in the sump after the sink has been used, which is a signature nothing else here produces.
- A disposal knockout plug left in, or a blocked disposal — 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.
- 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. Placed at this point because confirming it needs a meter on live terminals under the machine, which is technician work.
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 DFI 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 anything comes apart
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Bail the sump with a cup and a sponge before you tilt or draw the machine out, or the remaining water goes under the cabinets where it cannot be dried. Never tape or wedge the door latch to run a cycle with the door open — the latch cuts the heater and the wash pump together, and defeating it puts scalding water and a live element into the room.

When to call a technician
The boundary is the sump. The filter, the grate, the air gap and the disposal are owner work with the door open; the pump and anything under the machine are not, because a built-in dishwasher is usually hard-wired and has to be isolated at the panel and drawn out.
