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.
06 sections
When an ASKO dishwasher will not start, the cause can be a start condition rather than a failed part: the door not fully closed after Start/Stop was pressed, a delayed start still set, Child Lock on, or a closed water valve. Work through those in order, and if nothing changes, keep any displayed code as shown and book a diagnosis instead of retrying repeatedly.
An ASKO dishwasher that will not start 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 and reseat the water tank, empty the drip tray and grounds container, and read any maintenance or descale prompt before selecting another drink. 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.
Many machines pause to prevent overflow or protect water flow, so a full container, incorrectly seated tank, or overdue descaling can be the real cause. 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.
Start conditions on ASKO dishwashers
The cleaning guide for ASKO US dishwashers says to press Start/Stop and close the door within 4 seconds, and to confirm that delayed start is not activated. That is the sequence to compare against your own manual, since steps differ between models.
The same guide lists Child Lock as a reason the controls can seem dead, and it suggests holding a finger on each keypad for about a second rather than tapping, with the panel wiped with a damp cloth because grease on the keypads can interfere.
| Symptom | Likely cause | Safe check |
|---|---|---|
| No water flow | Tank or scale | Reseat tank, check prompt |
| Message displayed | Maintenance required | Follow guided steps |
| Stops early | Tray or grounds full | Empty and refit |
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.
- If the display shows a code, keep it exactly as shown together with the model label.
Safe to try
- Reseat water tank
- Complete descale prompt
- Empty service containers
Leave to a technician
- Open brew unit beyond manual
- Use unapproved chemicals
- Force internal valves
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.
Will not start versus seems not to stop
A dishwasher that keeps running after the wash can look like a unit that will not finish. The guide notes that on models with Turbo Dry the fan may run for 2 hours or more after the wash cycle ends, so read your model’s drying description before treating a running fan as a fault.
- No display at all: look at the power side and the outlet circuit from a safe distance.
- Display but no start: door, delayed start, and Child Lock come first.
- Starts and then stops partway: filters, drain, and the amount of detergent used are the documented places to look.
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
Does Child Lock stop an ASKO dishwasher from starting?
On many models a control lock keeps the buttons from responding. If the display looks normal but nothing happens, check your manual for how Child Lock is shown and released.
Why is my dishwasher still running after the wash is done?
Some models run a drying fan after the wash. If your model has Turbo Dry, the fan running for a long stretch can be normal, so check the manual before assuming a fault.
Does the water supply affect whether it starts?
It can, since a unit waiting for water may appear unresponsive. Confirm the shut-off valve is open, and if water still does not arrive, a plumber can verify supply pressure.

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.
