The short answer for Asko DSD
Dishes coming out dirty on an Asko DSD dishwasher is a loaded filter and sump more often than it is the wash pump, its impeller or the diverter valve. What moves it is the platform rather than the brand. Of the five causes ranked below, four are owner work and the remainder need a technician.
What you observe on these models
- Detergent left undissolved in the dispenser — The dispenser never opened, or the water was never hot enough to dissolve it.
- Cloudy glassware that never comes clean again — Etching rather than deposit, which is permanent and is caused by soft water and over-dosing rather than by a fault.
- A gritty film on glasses and the inside of cups
- White chalky deposits that wipe off with vinegar
- The machine runs its full cycle and nothing is properly wet at the end
- NEAR MISS — the machine never starts its cycle at all — Untouched dishes on a machine that never ran belongs on the will-not-start page.
Causes, most likely first on Asko DSD
- A loaded filter and sump — Modern machines filter rather than grind. A filter left uncleaned recirculates the debris it caught, which is why the film appears on everything at once. It earns this place because a blocked filter also starves the pump, so the spray pressure falls at the same time as the water gets dirtier.
- Loading, overfilling and items that shadow each other — Placed at this point because a deliberately sparse load is the cleanest test there is of whether the machine itself works.
- Incoming water that is not hot enough — It is here because it explains undissolved detergent in the dispenser, which is a direct physical observation rather than an inference.
- Blocked spray arm jets or an arm that cannot turn — Ranked here because the jets block progressively, so the cleaning degrades over months on a machine nothing has happened to.
- The wash pump, its impeller or the diverter valve — Low spray pressure on a machine whose filter, arms and water are all proven good — the pump is not developing pressure or the diverter is not sending it to the right arm. It sits at this point because it needs the machine pulled out and opened with the power isolated, so it is not owner work.
Check in this order, and why
- Lift the filter out of the sump and look at it — A filter with a mat of debris across it explains a film on everything, and it explains it before any part is suspected.
- Run a deliberately light, well-spaced load on the same programme — A machine that cleans a sparse load perfectly is a machine with nothing mechanically wrong with it.
- Run the kitchen hot tap until it is hot, then start the machine
- Spin each spray arm by hand and hold it up to the light
- Why this order and not another — It follows the ranking, not a generic checklist: on Asko DSD the first check separates a loaded filter and sump from loading, 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.

When to call a technician
Call when the filter is clean, both arms spin with clear jets, the load is sparse, the detergent is fresh and the water arrives hot, and the dishes still come out unwashed. That points at the wash pump or the diverter.
