It's mold, not your water.

Your ice maker smells because mold and biofilm are growing in the bin and on the parts — and old ice absorbs every odor from your freezer, so it tastes like whatever else is in there.

The fix is simple and takes about 15 minutes. Toss all the old ice, unplug the fridge if you can get to the ice maker easily, and wipe down every surface with a vinegar-water solution (half and half). If it’s really bad, use a tablespoon of bleach per quart of water instead — but rinse thoroughly. Then run a couple of batches of ice and throw those out before using any.

Also check two things: the water filter, if you have one (replace it if it’s old), and the drain line — some fridges get clogged and the moisture sits there, which is prime mold territory. And yes, a box of baking soda in the freezer helps, but it won’t fix the problem on its own.

Do this every few months and you’ll never taste freezer-scented ice again. Your ice only tastes as clean as the freezer it lives in.
