Symptoms
- Small white flecks visible in cubes
- Ice looks cloudy rather than clear
- White film left in the glass after ice melts
- More noticeable in areas with hard water
Likely causes
- CommonMineral content in hard waterCalcium and other minerals in tap water don't freeze evenly and show up as white specks or cloudiness.
- CommonOld or overdue water filterA worn filter lets more minerals and sediment through than it should.
- PossibleTrapped air causing cloudinessAir bubbles trapped during fast freezing create a cloudy appearance unrelated to minerals.
- Less commonBuildup inside the ice maker or water lineScale inside the components themselves can flake off into the ice.
What to do
- Replace the water filter if it's due, since a fresh filter reduces mineral and sediment passthrough.
- Discard a couple of batches of ice after changing the filter before judging results.
- If your home has hard water, consider a water softener or a filter rated for scale reduction.
- Clean the ice bin and check the fill tube for visible white buildup, wiping it out with a vinegar-water mix if accessible.
- Understand that cloudy (not flecked) ice from trapped air is a cosmetic issue only and doesn't indicate a problem.
- If white residue persists heavily after a filter change, have your water tested for hardness or mineral content.
