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.
A:AnswerBullet ice is shaped more or less like a bullet. It's typically cylindrical with a rounded tip on one end. It's often hollow in the middle, which allows it to melt more quickly. The smaller size will definitely fit inside a Poland Spring water bottle.

A:AnswerCheck the manufacturer warranty on it . When you get your new one make sure to buy the extended warranty for $20 it’s worth it .. and when it conks out you can walk up to customer service and if it’s available in store you can leave with your same ice maker that day.
A:AnswerMy wife and I use the steel thermos cups as well. The ice stays long enough that if we put it at our bedside at night, we wake up to left over ice in the morning.
