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.

Do you repair standalone undercounter ice machines in SouthPark homes?

Yes, residential undercounter ice machines are part of what we do. Common problems include a blocked drain, a failed water valve and scale on the evaporator plate. We diagnose the unit in place and explain the price before any repair.

My Cotswold fridge stopped making ice after a kitchen update. Why?

The supply line may have been kinked or pinched when the refrigerator was pushed back in, or the valve was left partly closed. Pull the fridge out carefully and look at the tubing. If the line is fine and the ice maker is getting power, the inlet valve or module may 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.

Thin Supply Lines and Undercounter Machines

Older ranch homes in Cotswold and Montclaire sometimes still feed the refrigerator through thin plastic tubing that has been moved during several kitchen updates. That tubing can kink behind the fridge or crack, leaving the ice maker starved or causing a slow leak on the floor. A clogged water filter produces the same small, hollow cubes, so replacing an overdue filter is the easiest first step.

In larger homes near Foxcroft and Quail Hollow, undercounter ice machines in a bar or butler's pantry are more common. Those units need a working drain and periodic cleaning, and a slow or blocked drain often leads to overflow or ice that melts into a block.

Checking It Safely and the Visit

Confirm the water valve to the fridge is open, check the ice maker's on switch and look for a jam of fused cubes in the bucket. Unplug the unit before clearing ice by hand. When we come out, we test the inlet valve, the ice maker module, the fan and the fill tube, and explain whether a part or a plumbing fix is needed.
