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.
08 sections
Maintenance that extends the life of ASKO appliances is regular cleaning of the parts the manual names: dishwasher filters and interior, door seals, dryer lint filters and condensers, and the washer drain filter. Choose one appliance at a time, follow its manual, and do the task before a symptom appears. Anything beyond those parts is repair, not maintenance.
Routine appliance maintenance 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
Choose one appliance at a time and use its manual to identify the filters, seals, trays, and cleaning cycles intended for homeowner care. 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.
Maintenance works best before there is a performance complaint, so put recurring tasks on a calendar rather than waiting for an error. 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.
| Task | Typical timing | Why it matters |
|---|---|---|
| Clean dishwasher filter | Monthly | Supports drainage |
| Wipe door seals | Monthly | Improves sealing |
| Clean dryer lint screen | Monthly | Protects airflow |
What ASKO’s cleaning guide lists, appliance by appliance
| Appliance | Task the guide describes | Why it matters |
|---|---|---|
| Dishwasher | Clean interior and filters at least once a year, more with heavy use | Reduces odor, film and drainage trouble |
| Dishwasher | Wipe the door edge with a damp cloth | Keeps the seal area clean |
| Washer | Clean the drain filter regularly | Catches coins, buttons and threads |
| Washer | Clean the detergent compartment with a soft brush and warm water | Limits residue |
| Dryer | Empty the lint filter after every load; rinse it monthly | Protects drying time |
| Condenser dryer | Clean the condenser about every 3 to 6 months | Keeps airflow through it |
These intervals come from the guide for ASKO US appliances, so check the manual for yours.
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
- Follow manual cleaning steps
- Use approved descaler
- Keep vents and seals clean
Leave to a technician
- Lubricate internal mechanisms
- Remove appliance panels
- Use harsh chemicals on seals
Matching the task to the appliance
The guide gives a different set of tasks for each appliance, which is why a single checklist can mislead. Some ASKO washers have a solid door seal that does not collect odor or debris and needs no cleaning, according to the guide, while where there is a seal, an opening at the top can collect debris and call for a wipe with equal parts vinegar and water. A dryer has its own filter list, and a condenser model has more to clean than a vented one.
Using water conditions to adjust the routine
For hard water of 9 or more grains per gallon, the guide describes about 1 ounce of citric acid in the washer drum on a hot regular cycle, repeated if needed. A water hardness figure from your supplier is worth knowing before you decide how often to descale.
What maintenance does not do
Cleaning will not fix a component that has failed. A clean machine that still misbehaves is information: the cause is not buildup, and you can stop cleaning and arrange a diagnosis.
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
How often should I run a cleaning cycle on the washer?
The guide describes a bleach cycle followed by a vinegar cycle, but not a fixed interval. Follow your manual and the drum cleaning program if your model has one.
Can I use bleach and vinegar together?
No. The guide lists them as separate hot cycles, never in the same one.
Is owner cleaning allowed?
Cleaning described in the manual is meant for owners. Opening panels or repairing internal parts is a different matter and belongs to a technician.

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.
