What Sterile Tub alert
actually means.
The machine counts washes and puts up the message on a schedule, not because a sensor found anything. Detergent film and lint build up in the tub and the drain path between cleanings, and a hot, empty cleaning run clears most of it.

What to do when Sterile Tub alert shows on the home applianceKind of codeReminders, not failures
Nothing has broken; the appliance has been counting hours, cycles or gallons and is asking for its routine care. A refrigerator lights a filter icon after about six months of water, a front-load washer suggests a tub-clean cycle after a set number of loads, a steam oven or a dishwasher asks for descaling or rinse aid, and some dryers remind you to check the exhaust. Do the task the reminder names, reset it the way the manual describes, and write the date in the service record.

Take everything out of the drum and run the tub-cleaning program named in your model's manual, with no laundry inside.

A laundry drum smelling musty gives off a damp, sour or mildew odor when the door opens, and passes it on to clean clothes, towels and the laundry room itself.

ASKO upkeep is mostly dish care and laundry: the dishwasher's filter and spray arms, and the washer's drain filter and the dryer's lint and condenser filters.

Before you book,
in this order.
Each step comes from ASKO's own guidance for Sterile Tub alert on its home appliances. Follow it to the end: the last card says whether this is a visit.
Take everything out of the drum and run the tub-cleaning program named in your model's manual, with no laundry inside.
Wipe the door glass and the detergent drawer while the program runs.
Leave the door open afterward so the drum dries.
Book a visit if a musty smell stays after the cleaning run and the drain pump filter has been emptied.
Cleared?
The reminder is gone from the display, the filter, the screen or the tub has been cleaned or swapped, and the appliance runs a full cycle without calling for it again. A clean-filter light or a descale prompt that returns in days rather than months usually means the part it watches is fouling faster than normal, so mention that when you book.
What not to do
The alert is a counter, not a report of a failed part, and the washer still runs if it is put off. A water, heater or drain code on the same display is a repair instead.
