What to do when CLEAN flashing 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.

Water or ice tasting stale is dispenser water, cubes or nugget ice with a flat, musty, chemical or freezer-food taste, often cloudy, slow to come or smaller than it used to be.

A Sub-Zero lasts decades when its condenser is kept clean, its door seals stay supple and its water filter is changed on schedule, and that is what a visit covers.

Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for CLEAN flashing on its home appliances. Follow it to the end: the last card says whether this is a visit.
Touch CLEAN and wait for the light to flash as the guide describes.
Pour the specified amount of undiluted ice maker sanitizer into the spray area under the water shutters.
Let the sanitizing cycle run to completion, roughly 30 minutes, before using the ice maker again.
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
A flashing CLEAN light is not a failure report; it is a scheduled step within the cleaning cycle itself, and it clears on its own once the sanitizing cycle finishes.

In Sub-Zero's own words
Touch "CLEAN". Wait three minutes until the CLEAN light flashes, then lift the water shutters and pour 1 tablespoon (15 ml) of undiluted ice maker sanitizer directly into the spray area.

A booking goes further when it has the reminder or code as shown, the model number from the rating plate, and a word on when that filter, screen or tub was last cleaned. With those three, the office can pack the right filter or cleaner for your appliance.
