Question 1

Do you keep it running all the time?  It seems to make a lot of ice once running.   I see people just let the ice melt.  Does that affect the taste?

Accepted Answer

We keep ours going 24x7.  It will stop production once the basket is full (the machine goes silent).  Once ice is taken out or the basket is emptied it resumes production.  It's fairly well insulated but it's not a freezer so the ice will eventually melt if left alone.  Since the top seals the unit, the flavor of the ice will not change - it just returns to its liquid state and refreezes.

Odd flavoring comes from contaminants introduced to the ice/water or the unit not being cleaned.  We clean ours every couple of weeks as directed and the ice still tastes great.

Question 2

How do you use the self cleaning mode on my mueller nugget ice maker model # NM-540. I received as a gift and do not have the instruction book?

Accepted Answer

Take the bucket out and you can put a small amount of white vinegar in the water well and add cool water to the max line. Then hold down the clean button and it will indicate with a light up that the cleaning process has begun. After it cycles put it by the sink or get a large pot and drain the water out using the tubs in the back. Lift up on the black connector for the tubes, you will be able to move them down to drain. The end of the tubes need to be lower than the machine. If you use vinegar, I would repeat the cleaning cycle with fresh water. It is best to use water that has been filtered, by refrigerator or a pitcher filer.

Question 3

In the morning the ice basket is empty & water tank full; "empty" light is flashing. Only if I open and close the lid does it start making ice. Why?

Accepted Answer

The tank went empty before it got filled back or maybe you need to clean it look in your booklet to see how to clean, maybe just sayin
