The short answer for Asko DOD
For the models listed under Asko DOD, dishes coming out dirty is most often blocked spray arm jets or an arm that cannot turn. The generic article for this brand puts the emphasis elsewhere; the roster below is why this page does not. Three of the four causes below are owner-checkable with nothing but hand tools; the rest are a service call.
What you observe on these models
- White chalky deposits that wipe off with vinegar — Hard water and rinse aid, which is a water-treatment question rather than a fault.
- Items at the back come out clean and the front does not — A loading or a door-seal pattern rather than a pump problem.
- 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 DOD
- Blocked spray arm jets or an arm that cannot turn — Each jet is small enough to be closed by a seed or a shard of label, and a tall item in the rack stops the arm turning at all. It sits at this point because it explains a machine that cleans one rack properly and the other not at all, which no filter or detergent fault does.
- 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.
- Detergent type, dose, rinse aid and water hardness — Placed at this point because a fresh box and a filled rinse-aid reservoir cost little and settle the question in one cycle.
- 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 is here 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
- Spin each spray arm by hand and hold it up to the light — An arm that catches on the rack, or jets you cannot see through, has explained the pattern of what is coming out dirty.
- 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.
- Why this order and not another — It follows the ranking, not a generic checklist: on Asko DOD the first check separates blocked spray arm jets or an arm that cannot turn 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.
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 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.
