My ice maker has a very slow drip into the ice bucket. This dripping isn't causing any damage or significant issues. What happens is where the water is dripping into the bucket, it grows ice up like a stalagmite. Once I week I take the bucket out and break loose this piece of ice so it doesn't get tall enough to cause problems.

Any idea where the leak would be originating from? I was going to guess the valve that feeds the ice maker above the bucket but I can't see anything.

Thanks for any suggestions.
