The cubes are jamming in the plastic portion of the mold, holding up the ejection of the cubes.
I recently installed a reverse osmosis system on the water line - but the ice maker worked fine for two months there after.
I'm sure there was a psi drop involved.
The ice that is hung up usualy seems smaller than normal.
Can I change the amount of water that is let into the ice mold?
Any other ideas?
