A:AnswerHaven't had that problem but did have rust stains in my first one we used a cleaning brush instead of a pad and when we got the 2nd one we changed to use spring water and so far nothing
A:AnswerYeah I noticed the same thing yesterday. Ughhh...I've had mine for about year and never noticed until yesterday. The black mold is way in the back near where the ice cubes form. I'm going to trash it today.
A:AnswerTry running a mild vinegar/water solution for a half dozen ice batches. That may clear the tubes and any calcium buildup on the nubs on which the ice forms.
