Ice that tastes bad usually comes down to one of three things: the cubes have absorbed odors from food in the freezer, the water filter is past its life, or the ice has sat in the bin too long. The fix is usually to empty and wash the bin and then change or flush the filter.
Quick diagnosis
| Symptom | Likely cause | First thing to try |
|---|---|---|
| Ice tastes like freezer food | Cubes absorbing odors from uncovered food | Wrap or cover food, then empty and wash the bin |
| Flat, stale taste | Ice sitting in the bin for weeks | Dump the bin and let a fresh batch fill it |
| Musty taste in both water and ice | Overdue water filter | Replace the filter and flush it as the manual directs |
| Plastic or chemical taste in a new install | New water line or filter not flushed yet | Run water through the dispenser and discard the first batches of ice |
| Tiny black specks after a filter change | Loose carbon from a new filter | Flush more water through the dispenser |
| Cloudy ice that tastes fine | Trapped air and dissolved minerals | Nothing; cloudy ice is normal |
A closer look
Odors in the freezer
Ice has a lot of surface area, and it picks up smells from whatever shares the air with it: onions, fish, uncovered leftovers, even a freezer that needs cleaning. Wrapping food well and keeping an open box of baking soda in the freezer helps more than most people expect.
The water filter
Most refrigerator filters use carbon to reduce chlorine taste and odor. Over time the carbon gets used up, and the water starts tasting like plain tap water again, or worse. Replace the filter on the schedule in your manual, then flush the amount of water it lists. A few black specks right after a change are loose carbon and usually clear with more flushing.
Old ice and a dirty bin
If your household rarely uses ice, the bottom of the bin can hold cubes that are weeks old. They shrink, fuse together and take on stale flavors. The bin and the chute can also build up a film. Wash the bin in warm water with mild dish soap, rinse well and dry it before it goes back. Check the manual before putting it in the dishwasher.
The water supply itself
Pour a glass from the kitchen tap. If it tastes the same as the ice, the issue is the water coming into the house, not the refrigerator. If the tap tastes fine, the source is in the fridge.
Who runs into this most
Households that use ice only now and then, freezers packed with loosely wrapped food, and anyone who has stretched a water filter well past its change date. New installations often have a plastic taste for the first several batches.
Prevention checklist
- •Change the water filter on schedule and write the date on it
- •Empty the ice bin every few weeks if ice sits unused
- •Wrap or cover food in the freezer
- •Wash the bin and chute whenever you change the filter
- •Flush new filters fully before using the ice
Time to call a pro
- •The bad taste returns soon after cleaning and a new filter
- •The filter housing leaks or the filter won't seat
- •The ice maker stops producing or the bin keeps overflowing
- •Water tastes fine but the ice still tastes off after a full cleaning
Travis's rule of thumb: Taste the tap first. If the tap is fine, the problem lives inside the fridge, and it's usually the filter or the bin.
