U-Line Ice Maker Making Small Cubes
Ice Maker Making Small Cubes is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
The part hard water destroys first
At 16 grains per gallon a fill valve narrows and a mould heater coats within months, so output tapers off gradually rather than stopping.
A blocked or frozen water supply line
Shows up as slow or stopped production, and is a plumbing-side issue rather than the ice-making mechanism itself.
A worn ice maker motor or mold assembly
The mechanical components that form and eject cubes wear out gradually.
Local conditions that matter here
Las Vegas water runs about 16 grains per gallon — genuinely hard, and among the hardest municipal supplies in the country. Anything plumbed here accumulates mineral faster than the manual assumes: fill valves narrow, heating elements fur, and output tapers off over months rather than stopping outright.
