First the filler hose was leaking and I was getting hollow ice cubes. I ordered the filler hose from the inlet valve to the ice maker and replaced it. About 15 minutes. Still no ice at all now. I ordered the water inlet valve and replaced it after reading it could cause hollow ice cubes. About 15 minutes. Still no ice. Took the ice maker out of the freezer and found the filler tube blocked with ice. I took a hair dryer to the filler tube and now the ice maker is working perfect again with no leaks and normal ice..
