I'm not sure if this is the right forum for this question, but I'll give it a try. Our refrigerator has a water and ice dispenser in the door. I change the filter every 6 months with a good quality filter. The water comes out clear. But the ice, after it melts, has clear particles that settle to the bottom. Our fastidious daughter discovered this and we can't figure out what is causing it. Does anyone know what is going on and how to fix it?
