Why is my Sub-Zero making small or hollow ice cubes?

Low water pressure, often from a clogged filter or partially closed valve, is the usual cause. Replacing the filter and checking the supply often fixes it.

My Pineville apartment fridge leaks near the ice maker line. What should I do?

Close the water supply valve behind or under the refrigerator if you can reach it, wipe up the water and report it to your landlord. The leak may be a cracked line, a loose fitting or a failed inlet valve. A technician can find which and replace the part.

Why does our townhome ice maker make small, hollow cubes?

Low water flow is the usual reason, most often from an overdue filter or a partly kinked supply line. Replace the filter and check the line behind the fridge. If the cubes stay small, the inlet valve may be weak and need testing.

Sub-Zero Ice Makers: What We Check First

Sub-Zero ice comes from two very different machines. Most refrigerators and freezers have an automatic ice maker inside the freezer compartment, fed by a water valve and line. Separately, Sub-Zero sells undercounter ice makers that produce clear ice in a dedicated cabinet, often installed in a bar, butler's pantry or outdoor kitchen. Undercounter units need a water supply, a drain, and either gravity drainage or a drain pump.

Clogged water filter or low pressure reducing ice production
Frozen fill line stopping the in-freezer ice maker
Scale buildup on undercounter ice maker evaporators
Drain pump or drain line clog in undercounter installations

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our Sub-Zero ice maker repair guide.

Water Lines and Filters in Compact Kitchens

When a refrigerator has been pushed hard against the wall in a compact Pineville kitchen, the plastic or copper water line behind it can kink or crack, and the ice maker is the first thing to stop. Townhomes and apartments with owner-supplied refrigerators may also have a filter nobody has changed since move-in, which slows the fill until cubes come out small and hollow.

Other causes include a fill tube frozen solid, an ice maker shutoff arm left up, a failed inlet valve, and a freezer too warm to finish the cubes. A leak under the fridge, especially on vinyl or laminate floors in an upstairs apartment, deserves attention before it reaches a neighbor below.

Check the shutoff arm, replace an old filter and look for kinks once the fridge is pulled out. If water is pooling, close the supply valve. The technician tests the valve, ice maker module and freezer temperature, and quotes before any repair.
