The short answer for Asko D
For the models listed under Asko D, dishes coming out dirty is most often detergent type, dose, rinse aid and water hardness. 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 runs its full cycle and nothing is properly wet at the end — A fill or a spray-pressure fault, and the most serious version of this complaint.
- Food debris redeposited on the upturned bases of cups — Classic filter-and-drain evidence: the machine is washing in water it has already used.
- Items at the back come out clean and the front does not
- Cloudy glassware that never comes clean again
- White chalky deposits that wipe off with vinegar
- NEAR MISS — water standing in the bottom at the end of the cycle — That is a drainage fault and it has its own page; dirty dishes are then a symptom of washing in old water.
Causes, most likely first on Asko D
- Detergent type, dose, rinse aid and water hardness — Old or damp detergent, an under-dose for hard water, or an empty rinse-aid reservoir all produce a machine that appears to have stopped cleaning. It earns this place because a fresh box and a filled rinse-aid reservoir cost little and settle the question in one cycle.
- A loaded filter and sump — Placed at this point because it is the single most common cause of poor cleaning on any machine built in the last couple of decades, and it is designed to be cleaned by the owner.
- Blocked spray arm jets or an arm that cannot turn — It is here because the jets block progressively, so the cleaning degrades over months on a machine nothing has happened to.
- Loading, overfilling and items that shadow each other — Ranked here because a deliberately sparse load is the cleanest test there is of whether the machine itself works.
- 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 is reached last because everything above it produces the same poor wash for a great deal less money.
Check in this order, and why
- Wipe a chalky glass with vinegar and check the rinse-aid level — Deposits that wipe away with vinegar are water hardness rather than dirt, and they need treatment rather than repair.
- 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.
- Spin each spray arm by hand and hold it up to the light
- Run a deliberately light, well-spaced load on the same programme
- Why this order and not another — It follows the ranking, not a generic checklist: on Asko D the first check separates detergent type from a loaded filter and sump, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.

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 when a sparse load on a hot programme, in a machine with clean filters and clear arms, still comes out unwashed. Report whether the spray is audible against the door mid-cycle — that single observation separates a pressure fault from everything else and it saves a visit.
