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.

To clean an ASKO dishwasher filter, switch the dishwasher off, remove the lower rack, turn the filter basket handle counterclockwise to take it out, wash the parts with soap and water, and reinstall them firmly. The cleaning guide says to do this at least once a year, and more often with heavy use.
Tackling a dishwasher filter is a chore nobody plans for, yet it is simple housekeeping rather than a sign of a broken machine. Work through observations that are safe and repeatable, and keep notes, since they help a technician should you later book an ASKO visit.
Below, normal upkeep is set apart from tasks that need instruments or dismantling. Never get past a door lock, safety switch, or displayed message to keep the dishwasher in service. Notes jotted down now make any later diagnosis quicker and sharper.
Start with the simple conditions
Let the dishwasher be switched off and cool first. Then follow your manual to find the filter, twist it free, and lift it out, doing only what the instructions describe. The unit stays in place and no panel, fitting, or control gets forced. If cleaning changes how it behaves, run one regular cycle before drawing any conclusion.
Scraps lodged in the mesh or the housing around it can weaken washing and slow draining, most of all where plates go in without a rinse. Take note of whether the trouble shows every cycle, only with particular programs, or once the dishwasher has run for some time. That clue outweighs restarting the machine repeatedly.
| Job | Frequency | Approach |
|---|---|---|
| Flush the filter | Every month | Under warm running water |
| Remove stuck debris | When it shows | With a gentle brush |
| Inspect the filter area | At every clean | Soft wipe |
The steps as the cleaning guide describes them
The ASKO US cleaning guide describes removing the lower rack, turning the filter basket handle counterclockwise to remove it, and lifting the handle to separate it from the fine filter. A flat rectangular filter cover surrounds the filter area and lifts off. The vent on the filter faces the front of the unit when installed, which is the detail to check when you put it back.
All filter components are washed with soap and water and then reinstalled. Check your own manual for the order on your model, since layouts differ.
Safe checks that protect the appliance
Model-specific controls, how to reach the filter, and the right service intervals are in your use-and-care manual. Clean just the parts it describes as owner-serviceable, with the products it names, and fit each removable part back as the designers intended.
Before the next run, clear whatever is in the way, cut down an unusually heavy load, and check that air, the water supply, and door clearance are not held back. Steer clear of repeated resets: they may conceal a fault that comes and goes and leave water, heat, or pressure where it should not be.
- Jot down any displayed message or code before you dismiss it.
- Examine exposed hoses, vents, seals, and plugs without shifting electrical connections.
- Make one measured test instead of a quick succession of tries.
You can do this
- Flush with warm water
- Scrub with a gentle brush
- Lock the filter back firmly
A technician should do this
- Poke with sharp tools
- Operate the machine filterless
- Put a hand into the pump area
What does cleaning a dishwasher filter fix?
A clean filter helps with odor inside the dishwasher and water standing above the filters. If the unit still does not drain, verify the drain line is not clogged.
The guide’s quick fixes link dirty filters to specific symptoms: odor inside the dishwasher, and water above the filters. If the unit does not drain, the guide says to check and clean the filters and verify that the drain line is not clogged, and it describes a manual drain by holding Start/Stop for 3 seconds.
A clean filter will not fix a drain pump fault, a kinked hose, or a blocked sink connection. If you have cleaned the filters and the water still stands, the cause is further along the drain path.
Common mistakes
Running the dishwasher without the filter, forcing the basket handle, or refitting the cover facing the wrong way can all cause new problems. If a part will not seat, stop and read the manual rather than pressing harder.
Related care
When you are cleaning the filter, it is also a good moment to wipe the door edge, since food debris and residue collect there as well.
Know when the symptom needs diagnosis
A filter that is clean and refitted yet leaves the symptom in place means the problem lies past what an owner can handle. Control boards, gas connections, refrigerant lines, motors, pumps, heating circuits, and the wiring inside the cabinet are the territory of a technician with test instruments, who can make certain nothing unsafe is left behind.
Line up service quickly if things are deteriorating, a breaker trips, there is leakage near electrical parts, a hot or burnt odor appears, a new grinding noise starts, or no normal cycle can be completed. Stop using the machine if it shows a safety warning.
What to tell the technician
Hand over the model number, a precise description of the symptom, the time it began, the settings chosen, and what the safe checks revealed. A photograph of a displayed code or a short description of a sound is also useful, yet no cover should ever come off to get it.
Noticing details will not mend a dishwasher, though it is the wisest place to begin. Settle the easy causes, keep any error information worth having, and leave anything electrical, gas, sealed-system, or mechanical inside the machine to a trained ASKO technician.
Frequently asked questions
How often should I clean the filter in an ASKO dishwasher?
The ASKO cleaning guide says at least once a year, and more often with heavy use. Dishes that come out gritty or a smell from the tub are signs it is due.
Can I run the dishwasher without the filter?
No. The filter is part of the wash and drain path, and running without it lets debris reach places it should not.
Why is there standing water above the filter?
The guide says to clean the interior and filters when water sits above the filters. If it remains after cleaning and the drain line is clear, book a diagnosis.

Official manuals and support notes are available on ASKO Support.
Part orders should wait until the full model number is recorded, because a revision to the board or sensors can change the part number that is correct.
A power reset done once may clear a short-lived fault, while the same code returning repeatedly generally means a physical cause is still there.
Between visits, keep vents and filters free of blockage, since limited airflow regularly looks like an electrical or sensor failure.
If you spot water or sparks, or smell something burning, shut the appliance off and arrange for a professional to inspect it.
