The short answer for Asko DBI
Dishes coming out dirty on an Asko DBI dishwasher is loading, overfilling and items that shadow each other more often than it is the wash pump, its impeller or the diverter valve. What moves it is the platform rather than the brand. The first checks cost nothing, and three of the four causes listed here can be settled without a meter.
What you observe on these models
- 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.
- 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 — 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 DBI
- Loading, overfilling and items that shadow each other — A dishwasher cleans with line of sight. Bowls nested together, a tray across the front and a pan blocking the arm leave whole areas untouched. Placed at this point because it explains an intermittent complaint that follows the load rather than the machine, and it costs nothing to test.
- A loaded filter and sump — It is here 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 — Ranked here 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 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
- 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.
- 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.
- Wipe a chalky glass with vinegar and check the rinse-aid level
- Why this order and not another — It follows the ranking, not a generic checklist: on Asko DBI the first check separates loading 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.
Breaker first, then the water
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a built-in machine there is usually no plug at all, so the breaker is the isolation point and it is worth proving the panel is dead before reaching 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.
