Full guide
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.

Dishes that come out wet from an ASKO dishwasher usually point to rinse aid, loading or the drying program before they point to a failed part. Fill the rinse aid compartment, tip cups so they cannot hold water, and give the cycle time to finish before opening the door. If every load is wet even then, ask about the drying option on your model before suspecting anything else.
A dishwasher leaving dishes wet can be frustrating, especially when it interrupts a normal household routine. A symptom alone does not identify a failed part, so start with observations that are safe, repeatable, and useful if you later arrange an ASKO service visit.
This guide separates routine care from work that requires testing or disassembly. Do not bypass a lock, safety switch, or error message to keep an appliance running. Taking a few notes now can make the eventual diagnosis faster and more accurate.
Start with the simple conditions
Fill the rinse-aid dispenser, confirm its setting is not at minimum, and angle cups or plastic containers so they cannot hold water. Make the check with the appliance in its normal position and without forcing panels, fittings, or controls. If the result changes after a simple adjustment, run one normal cycle or operation before drawing a conclusion.
Condensation drying depends on warm surfaces and airflow, so opening the door before the program finishes can reduce the drying result. Look for a pattern: whether the issue happens every time, only with a particular load or setting, or after the appliance has been running for a while. That distinction is more valuable than repeatedly restarting the appliance.
| Result | Likely cause | Safe check |
|---|---|---|
| Wet plastic | Material retains water | Angle items |
| Pooled mugs | Loading position | Tip cups downward |
| All loads wet | Rinse aid or setting | Refill rinse aid |
Wet versus not clean versus not hot
These sound similar but are different complaints. Wet dishes mean the drying phase did not finish the job. Dirty dishes mean the wash did not work. Dishes that are dry but warm are normal. Mixing the complaints sends you to the wrong check.
Compared
| What you notice | What it can point to | What a check tells you |
|---|---|---|
| Only plastic items are wet | Plastic holds less heat | Angling them or placing them on the upper rack changes the result |
| Water in mug bottoms | Loading position | Tipping them downward fixes it |
| Everything wet, rinse aid level low | Rinse aid empty | Refilling shows the effect over a load or two |
| Everything wet, rinse aid full, door opened early | Cycle not finished | Letting it complete the cycle |
Safe checks that protect the appliance
Consult the use-and-care manual for model-specific controls, filter access, and maintenance intervals. Clean only parts described as user-serviceable, use the recommended cleaning products, and refit every removable part exactly as it was designed to sit.
Before trying another cycle, clear obstructions, reduce an unusually heavy load, and make sure airflow, water supply, or door clearance is not being restricted. Avoid repeated resets: they can hide an intermittent fault and may leave water, heat, or pressure where it should not be.
- Record any displayed message or error code before clearing it.
- Check visible hoses, vents, seals, and plugs without moving electrical connections.
- Use one controlled test rather than several back-to-back attempts.
Safe to try
- Use rinse aid
- Load for drainage
- Let cycle finish
Leave to a technician
- Open heater circuits
- Alter drying controls internally
- Run damaged racks
What the ASKO guide says about drying
The cleaning guide for ASKO US dishwashers gives two responses to dishes that are not dry: verify that rinse aid is used and the compartment is full, and add the Long Dry cycle option. The sheet for one ASKO model also lists an Extra dry option and a low rinse-aid indication shown in the display, so some models tell you directly when the compartment needs refilling.
The guide also says that on models with Turbo Dry the fan may run for 2 hours or more after the wash cycle ends. This is why a dishwasher can seem not to turn off. The brochure for one model describes fan-forced drying with fan-assisted evacuation of moisture, so dishes are dry and cool. Whether your dishwasher has this depends on the model.
What each result does and does not prove
If rinse aid and the Long Dry option fix the problem, the dishwasher was working as designed. If wetness is limited to certain items, loading or material is the reason. If every load is still wet with a full rinse aid compartment and a completed cycle, drying is a problem for a technician to assess, and no heating circuit is for the owner to open.
Know when the symptom needs diagnosis
If the basic checks do not change the symptom, stop at the user-serviceable boundary. Internal wiring, heating circuits, pumps, motors, refrigerant lines, gas connections, and control boards need the correct test equipment and a technician who can verify the repair safely.
Arrange service promptly when performance is getting worse, the appliance trips a breaker, leaks near electrical parts, smells hot or burnt, makes a new grinding noise, or cannot complete a normal cycle. Do not continue operating an appliance that gives a safety warning.
What to tell the technician
Share the model number, the exact symptom, when it began, what settings were selected, and the results of the safe checks above. A photo of a code or a short description of the sound can also help, but never remove a cover to obtain it.
Careful observation is not a substitute for repair, but it is the best first step. Address the simple conditions, preserve any useful error information, and leave electrical, gas, sealed-system, and internal mechanical work to a qualified ASKO technician.
Common questions
Why is the dishwasher still running after the wash is done?
On models with Turbo Dry, the guide says the fan can run for 2 hours or more after the cycle. Check whether your model has it before treating this as a fault.
Is it normal for plastic to stay wet?
Plastic retains less heat than glass or ceramic, so it often needs help from angling or the Long Dry option.
Can too much rinse aid cause problems?
Follow the dispenser’s setting in the manual; adjust only as the manual describes.

Official manuals and support notes are available on ASKO Support.
Write down the full model number before ordering parts. Board and sensor revisions can change which part number is correct.
A single power reset can clear a temporary fault, but repeated returns of the same code usually mean a physical cause remains.
Keep vents and filters clear between visits. Restricted airflow often mimics electrical or sensor failures.
If water, burning smells, or sparking are present, stop using the appliance and arrange a professional inspection.
