Stale cubes that shrink, cloud over and pick up freezer odors, and anything with specks, slime or flakes, go too. By [IceMakerRepair.center technical team](https://icemakerrepair.center/authors/technical-team/) Published September 26, 2026 ## At a glance. Ice is treated as a permanent fixture of the freezer, but the bin is a small reservoir of water that sits for days or weeks. A few events, and a few things you can see, mean the whole load goes into the sink. Read the whole guide ### Any water advisory Dump every cube made from tap water CDC's household guidance, and it applies under boil, nitrate and other notices. ### Floodwater contact Discard it FDA says to throw out any food that may have come into contact with flood water. ### Closed freezer, no power About 48 hours full, 24 hours half full FDA's figures; a bin that thawed into a block is past that point. ### New install or new line The first few batches GE and U-Line both tell owners to throw away the earliest ice. In this guide 1. When the water that made it was not safe 2. After a power outage or a flood 3. After a new line, filter or machine 4. Ice that has simply been there too long 5. Things you can see in the bin 6. Questions ## When the water that made it was not safe Deciding when to throw out ice starts with the simplest rule, which is also the strictest: ice is only as safe as the water it was made from on the day it froze. When the local utility issues a boil notice, CDC's household guidance is to throw out all ice made with tap water and not to use ice from trays, dispensers or ice makers. The same toolbox, in its questions for a nitrate advisory, tells households to throw out all ice previously made with tap water as well. That covers every plumbed ice maker in the house at once: the door ice maker, the freezer ice maker, an undercounter unit in the bar and any trays filled at the sink. A well owner who finds out after a test that the water carries bacteria or nitrate is in the same position as a city customer under a notice, and the bin goes too. ### The ice made just after the notice ends Throwing out what was in the bin is not the end of it. The first bin made once the notice is lifted comes from water that sat in the valve, the filter and the fill tube, so CDC's checklist has it filled completely and thrown away as well. The full routine is in our guide to ice after a boil water notice.

FDA says a full freezer holds its temperature for about 48 hours with the door closed, and a half-full one for about 24. Cubes that are still separate and hard when the power returns kept frozen and can stay. Cubes that have welded into one block, or a bin with water in the bottom, thawed and refroze, and that water sat in the bin while it did. Flooding is simpler: FDA's advice is to discard any food that may have come into contact with flood water, and ice counts as food. An undercounter ice maker that stood in floodwater has water in its pump, drain and bin, and it needs cleaning and a check before any ice from it is used again. - Separate, hard cubes after a short outage: keep them. - Cubes fused into a block or water in the bin: throw them out. - Any ice touched by floodwater: throw it out. - An undercounter unit that stood in water: clean and inspect before use.

GE's owner's manual tells people to throw away the first few batches of ice to allow the water line to clear, and U-Line's nugget ice maker guide asks for the ice made during the first two or three hours to be discarded because dirt or scale may come loose from the line. The same logic applies after a new filter cartridge, a repaired inlet valve or a line that was disconnected so the unit could be pulled out. The first cubes often carry carbon dust from the cartridge or trapped air that makes them cloudy and brittle; both clear within a few cycles.

The cubes lose water straight to the cold dry air of the freezer, their corners round off, and they take on a dull, cloudy look. GE's manual puts it plainly: if ice is not used often, old cubes become cloudy, taste stale and shrink. A bin that is always full and rarely emptied is the usual sign that half of it has been there for a month. Old cubes also pick up smells. Ice is porous enough on its surface to take on odors from uncovered food, fish, onions or a spilled container, and a drink shows it instantly. If the ice tastes like the freezer, dump the bin, wash it, and look for the source before the next batch fills. ### Countertop nugget ice and its meltwater A countertop nugget ice maker is not a freezer. Its nuggets slowly melt in the bin, the meltwater runs back to the reservoir, and it is frozen again. GE's Opal manual recommends draining the machine when you are not using much ice, because meltwater recirculating over and over may affect the taste.

They come from the ice maker, the bin or the water, and each points to a different problem, so it is worth noting what you saw before you rinse it away. Throwing out the ice clears the symptom. If the same thing is back within a week, the cause is still in the machine or the water, and the next step is cleaning, a new filter or a visit. - Black grains that fade after a few batches: filter carbon. - White flakes or a gritty feel: scale in the machine. - Pink, orange or black film: growth in the bin or chute. - Hard fragments that are not ice: a broken part, so stop using the ice and book a check. ### Specks, flakes and slime Black specks are often carbon from a new filter, and they stop once it has been flushed. White flakes floating as the ice melts are usually mineral scale, common in nugget and clear-ice machines on hard water. Pink or black slime on the bin, the chute or the ice itself is growth, and everything it touched gets washed. ## Where to stop Stop using the ice and book a check if fragments of plastic or metal turn up in it, if slime or scale returns within a week of cleaning, or if the bin keeps filling with fused or wet ice while the freezer seems cold, which points to a fill or temperature problem rather than old ice.

They write from what they find at the supply valve, along the fill tube, in the ice bin and at the drain, and they check it against the maker's own manuals wherever one is published.

Do I have to throw all of it out? If it welded into a solid block after an outage, yes. A few cubes stuck together at the edges is normal; GE notes that joined cubes happen in ordinary use. ### How long can ice sit in the bin before it goes bad? There is no published expiry for ice. It goes stale rather than unsafe: it shrinks, clouds and takes on odors. Using or emptying the bin every week or two keeps it fresh. ### Can I just rinse the cubes instead of throwing them away? Not after an advisory or floodwater, and not when there is slime or debris. Rinsing melts the surface and refreezes a wet layer onto everything else in the bin. ### Do I have to dump the ice after changing the filter? It is worth dumping the next batch or two. The fresh cartridge can release carbon dust and air, and both show up in the first cubes. ## The problems behind it. Each has a page of its own: what it usually means and the causes in the order worth checking. [All 17 problems](https://icemakerrepair.center/problems/) Problem ### Ice Tastes or Smells Bad 5 causes, cheapest first Problem ### Cloudy or Discolored Ice 6 causes, cheapest first Problem ### Ice Clumped or Frozen in the Bin 5 causes, cheapest first ## When it needs a technician. The repairs on the right are where this guide ends when the checks do not settle it. ### Ice bin and door seal repair The bin, its rails, the compartment cover and the gaskets that keep the ice cold and dry, replaced when a crack, a warped cover or a torn seal lets warm air in and leaves the ice wet, clumped or dripping. ### Undercounter ice maker cleaning and descaling A full cleaning and descaling of a built-in or countertop ice maker: scale off the plate, cylinder or fingers, slime out of the reservoir and drain, the condenser brushed, and the unit sanitized before the ice comes back. ### Water filter and supply line service The filter, the shutoff valve and the thin line that bring water to the ice maker, checked for flow, leaks and age, with a worn line or saddle valve replaced and a new filter seated properly. ## More in water, power and clean ice.
