The nugget control tallies total icemaking runtime and starts this rolling flicker once six months have passed, keeping it up until the built-in clean-and-rinse routine is actually completed. It has nothing to do with a error reading; the machine keeps making ice while the lamps flicker. Viking home appliance display · also shown as rolling flicker, cleaning signal What to do when Lamps flicker twice in sequence shows on the home appliance ### Kind of code Reminders, 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. ### Usually leads to No service Mix the manual's stated 2 ounces of Viking Ice Machine Cleaner into two quarts of water; no substitute cleaner is listed as safe. ### Shows up as Water or Ice Tasting Stale: Filter Age, Scale and Idle Lines 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. ### Make Viking Viking kitchens tend to mix heavy gas cooking with built-in cold storage, so a visit splits its time between burner ports and hood filters and the refrigerator's coil. ### Source Viking FNIU515D nugget ice machine Install / Use & Care manual Viking FNIU515D nugget ice machine. ## Before you book, in this order. Each step comes from Viking's own guidance for Lamps flicker twice in sequence on its home appliances. Follow it to the end: the last card says whether this is a visit. 01 Mix the manual's stated 2 ounces of Viking Ice Machine Cleaner into two quarts of water; no substitute cleaner is listed as safe. 02 Switch the mode to OFF, wait roughly 30 seconds, then add the solution through the ice spout as the guide describes. 03 Follow the clean-and-rinse sequence through to the end and switch back to ICE. 04 Book a visit if the flicker continues after a fully completed cycle. ### 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 This rolling, one-after-another flicker is not the same signal as a numbered error, and it does not mean icemaking has stopped. Older Viking 5 Series nugget models use a steady Time to Clean light instead of this pattern. ## What you may notice with it.

Mix the manual's stated 2 ounces of Viking Ice Machine Cleaner into two quarts of water; no substitute cleaner is listed as safe. If it comes back, it needs a visit. ### How is the Viking nugget's cleaning reminder counted? By total icemaking runtime rather than the calendar, so a lightly used machine reaches the six-month mark later than a heavily used one. ### Is vinegar an acceptable substitute for the Viking nugget cleaning solution? No; Viking's own guide calls only for its branded Ice Machine Cleaner and warns that other cleaning products can damage the machine. ### How long does the nugget machine's cleaning cycle take from start to finish? Roughly 10 minutes of automatic cleaning plus a rinse, and the flicker stops once the whole sequence has run through. --- **[Read on the site: Viking nugget-ice unit's rolling flicker: a cleaning cycle is due](https://appliancemaintenance.center/error-codes/viking-nugget-rolling-flicker/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
