Our experience with the ice make
We found that if we accidentally left the ice maker operating (bar down) on ours while in travel and motion, that the water would not set up and freeze in dispensed cubes. Instead it kept spilling water into the collection bin and froze in a large block.
Our fix was simple-- raise the bar and we don't make ice while the motorhome is in motion. We drop the ice maker bar to make ice only when the rig is set up and still in a campsite or home for an extended period with no motion.
Hope this helps?
