What to check before you call
Safe observations first. Stop if anything involves smoke, gas, water near electricity, or a panel you would need to remove.

Wet dishes after an ASKO dishwasher cycle usually come down to rinse aid, loading, or how the drying program is set, not to a failed part. Fill the rinse-aid compartment, check the drying options in your manual, and give the dishes time before opening the door; if everything is wet in every load even then, book a diagnosis.
Dishes that come out damp put a dent in the daily routine, but wetness by itself does not point at one broken component. Begin with checks that are safe, can be repeated, and give a technician something solid to work from should you book an ASKO visit later.
What follows draws a line between ordinary upkeep and jobs that call for measuring equipment or taking the machine apart. Never defeat a door lock, a safety switch, or a displayed warning just to keep the dishwasher going. A few written observations today will speed up and sharpen any diagnosis.
Start with the simple conditions
Top up the rinse-aid dispenser, make sure its dial is not turned to the lowest step, and tilt cups and plastic tubs so their bases cannot hold a puddle. Leave the dishwasher where it stands and do not force any panel, fitting, or control. When a small change alters the outcome, confirm it with a single regular program before deciding anything.
Dishes dry from the heat stored in their surfaces plus moving air, so pulling the door open ahead of the end of the program weakens the result. Note whether wetness shows up in every load, only with a certain program or option, or mainly late in a long run of cycles. Spotting that pattern tells you more than starting the machine over and over.
| What you see | Probable reason | Check to make |
|---|---|---|
| Damp plastic items | Plastic holds on to water | Tilt them so water runs off |
| Water in mug bottoms | Position in the rack | Face cups downward |
| Every load damp | Rinse aid or option choice | Fill the rinse-aid compartment |
Which ASKO drying options help dishes dry?
The cleaning guide says that when dishes are not dry, you should verify rinse aid is used and the compartment is full, and add the Long Dry cycle option. Product sheets for some models list an Extra dry option and a low rinse-aid notification on the display, so the fastest checks are a glance at the display and a look at the compartment.
Some models use fan-forced drying. Product sheets describe Turbo Drying and Turbo Drying Express, the latter as combining fan-forced drying with fan-assisted removal of moisture. Because of this, dishes can feel warm and slightly damp at the moment the program ends and finish drying afterward. Your manual lists the options your model offers.
Safe checks that protect the appliance
Model-specific controls, where the filters sit, and how often to service them are all laid out in your use-and-care manual. Only touch what it labels as owner-serviceable, use the cleaners it recommends, and seat every removable component back the way it was designed to go in.
Prior to another run, take out anything that obstructs, lighten a very full load, and look for anything narrowing airflow, the water supply, or the space the door needs to close. Resist cycling the power again and again, since that can mask an on-and-off fault and leave water, heat, or pressure in places it does not belong.
- Jot down any message or code shown on the display before you dismiss it.
- Look over exposed hoses, vents, seals, and plugs, leaving electrical connections where they are.
- Do one deliberate test instead of a string of quick retries.
Fine to try
- Keep the rinse aid filled
- Load so water drains off
- Allow the program to end
Hand to a technician
- Opening up heating circuits
- Changing drying controls from inside
- Using racks that are damaged
Know when the symptom needs diagnosis
Once the easy checks fail to shift the symptom, owner work stops. Anything involving internal wiring, heater circuits, pumps, motors, refrigerant lines, gas fittings, or control boards needs proper test gear plus a technician who can prove the fix is safe.
Get a technician booked quickly when the dishwasher keeps getting worse, a breaker trips, liquid collects near electrical parts, you smell something hot or burnt, a fresh grinding noise starts, or a normal program no longer finishes. If a safety warning appears, stop running the machine.
Is a running dishwasher fan after the cycle a fault?
The cleaning guide notes that on models with Turbo Dry the fan may run for two hours or more after the wash cycle ends, which is why the unit can seem not to turn off. If you hear a fan after the cycle finishes, that may be the drying phase, not a problem. Opening the door early cuts that phase short and lets the steam escape into the kitchen instead of drying the load.
Wet spots in the same places every time often point to loading rather than the machine. Plastic holds water differently from glass or steel, and cups that sit flat collect pools. White film or poor results can have other causes, and the guide points to cleaning the interior and filters, using less detergent, and using fresh granular detergent where it applies.
When drying stays poor
If rinse aid is full, the options are set, the load is angled to drain, and the dishes are still wet, record which options you used and whether every load is affected. That pattern helps a technician decide whether the issue is the dispenser, the drying system, or something else.
What to tell the technician
Tell the technician the complete model number, exactly what the dishwasher does, when you first saw it, which options were chosen, and how each safe check turned out. Photographing a displayed code or describing a noise in a sentence helps, but do not take off a cover to get either.
Watching closely will not repair anything, yet it is the right place to start. Deal with the easy factors, keep any helpful error details, and leave electrical, gas, sealed-system, and internal mechanical jobs to a qualified ASKO technician.
Quick questions
Should I add the Long Dry option?
The cleaning guide suggests adding the Long Dry cycle option along with checking the rinse aid. Your model manual lists the drying options it has.
Why is the fan running after the dishwasher finishes?
On models with Turbo Dry, the guide says the fan may run two hours or more after the wash cycle, which can make the unit seem not to turn off.
Does rinse aid really matter?
Yes. The guide lists an empty or unused rinse-aid compartment as a first thing to check for dishes that are not dry, and some models show a low rinse-aid notice.

Official manuals and support notes are available on ASKO Support.
Before you order any part, note down the complete model number, because board and sensor revisions may alter which part number fits.
A lone power reset may wipe out a brief glitch, whereas a code that keeps reappearing after it usually signals that something physical is still wrong.
Between service calls, keep filters and vents unobstructed. Poor airflow tends to imitate electrical or sensor trouble.
Spotting water, a burnt odor, or sparking means the dishwasher should be switched off and left alone until a professional has looked it over.
