Even when your well or municipal water supply provides healthy, potable water to your ice maker, some impurities may remain. These can affect the smell or taste of the ice cubes, and therefore the beverages in which you serve them. A taste and odor water filter on the incoming water-supply line--such as our charcoal "Universal Replacement Water Filter"--can help a lot.
Also, over time, the ice cube bin can absorb difficult-to-remove odors from the freezer. We recommend that you replace the bin every 2 to 3 years--whenever it seems to be retaining objectionable odors and transferring them to the ice cubes.
To help keep your ice tasting its best, empty out the ice and wash the ice bin every 2 to 3 months. Also try to keep the foods in your refrigerator covered, because the ice cubes absorb many odors and tastes (baby formula, onion, and so on).
If the cubes coming from your icemaker are too small, it may be time to replace the water filter. Or the shut-off water-supply valve may be clogged. Check the water-supply valve first, to see if there is an obstruction. If the cubes are still small when you're sure that the water supply is good, try replacing the water filter.
