Every couple of years this happens to my ice cubes. After trial and error,
I finally discovered the cause was the supply line stopping up in the
fitting where the copper tubing supply line joins a galvanized pipe. The
solution is to take off the supply line and flush it out good. I would
imagine that any impediment in the supply line, filter, or valve would cause
the cubes to be small or hollow. The ice tray is just not getting its full
complement of water during the fill-up.

Every once in a Blue Moon i will work on a ice maker in a Refrigerator
and
was thinking about the hollow ice cubes on the ice maker and what was
the
general cause. I had this trouble on my ice maker at my house about 3 or
4
years ago and someone here told me what it was and I fixed it and i have
slept since then and it is starting to do it again , just a little. Can
someone refresh my memory?

Hollow ice cubes: - This is often a low water problem, the fill valve
and shut off valve are bad for getting a build up inside them that
slows the water pressure to the icemaker. I find it best to replace
them both for this type of problem. A very LARGE problem in the last
few years has been the self piercing shut off valve have been clogging
up with calcium and junk! Replace the self piercing shut off valve
with a drill type shut off valve. You drill a 1/4" hole into the pipe
and install the shut off valve the same way you would with a self
piercing valve. Sometimes the shut off valve is mounted on the bottom
of the house pipe and this allows sediment and such to enter the
icemaker lines and can clogg the shut off valve or fill valve, shut
off should be on the top or side of the house pipe. Tired water filter
can slow the fill pressure down as well.

Hope something here helps,
