Comparing Ice Maker Models & Types
Sub-Zero makes two kinds of ice makers. Each one fails in its own way. The right fix starts with knowing which type you own. Here is how they compare.
Feature | Freezer Ice Maker | Undercounter Ice Maker |
Location | Inside the freezer. | A 15 inch unit under the counter. |
Ice type | Crescent shaped cubes. | Clear cubes. |
How it stores ice | Ice stays frozen in the bin. | The bin melts ice slowly while new cubes form. |
Common problems | No ice, hollow cubes, a jammed bin, and leaks. | Slow ice, cloudy ice, and drain faults. |
Care needed | Change the water filter about every 6 months. | Clean and descale on a set schedule. |

Common In-Unit Freezer Ice Assembly Faults
A freezer ice maker needs three things. It needs water, cold air, and a working ice maker unit. If one fails, the ice stops. These are the faults we fix most.
No Ice but the Freezer Is Cold
Likely causes: A failed water valve, a frozen fill tube, a clogged filter, or a dead ice maker unit.
What we do: We test the water flow. We check the valve and the fill tube. If the unit does not cycle, we replace it.
Small, Hollow, or Misshapen Cubes
Likely causes: Low water pressure, a half-blocked filter, or a weak water valve.
What we do: We measure the water supply. We replace a blocked filter. We repair or replace the valve.
Ice Clumped Together in the Bin
Likely causes: Ice that sits for weeks, a door that opens often, or a freezer that runs warm.
What we do: We check the freezer heat and the door seal. Then we clear the bin and reset it.
Water Leaking Into the Freezer
Likely causes: A water valve that overfills, a cracked fill cup, or a fill tube that is not seated right.
What we do: We replace the leaking part. Then we confirm that each fill stays inside the mold.

Troubleshooting Under-Counter Ice Machine Operations
Sub-Zero undercounter units make clear ice in a new way. They need their own kind of check.
Problem | What Usually Causes It |
Ice slowed down | Scale on the ice plate or a dirty condenser. |
Cloudy or soft cubes | Mineral buildup or a weak water flow system. |
Ice will not harvest | A failed harvest valve, thermistor, or control board. |
Water on the floor | A clogged drain or a failed drain pump. |
Unit runs but makes no ice | A water supply fault or a sealed system issue. |
Loud grinding or humming | A worn water pump or a bad condenser fan motor. |
We repair UC-15I models, drain pump models, and outdoor rated units. Do you see any of these problems? Call (949) 647-4239.
Cleaning and Descaling in Orange County
Much of Orange County has hard water. The minerals build up inside ice makers over time. Scale is a top reason undercounter units slow down. It also causes cloudy ice. A simple routine helps a lot.
- Descaling: Run a descale cycle every 6 months. Do it more often if your water is very hard.
- Condenser cleaning: Clear dust from the condenser twice a year. This keeps ice output steady.
- After filter changes: Toss the first few batches of ice. This flushes out loose carbon.
- Long trips: Turn the ice maker off. Empty the bin.
Heavy scale that a normal cycle cannot remove? Our techs can deep clean the unit. We also replace parts that the scale has damaged.
How to Get Better Tasting Ice
Bad smell or taste in ice is often a storage issue. It is rarely a machine fault. These steps usually fix it.
- Change the water filter on time.
- Empty the bin. Wash it with warm water and mild soap.
- Cover strong-smelling food in the freezer. Odors can pass to the ice.
- Use fresh ice often. Do not let it sit for weeks.
- Taste your tap water. An ice maker cannot filter out everything.
Still tasting something off? Our techs can check the water line and the ice maker unit.

(FAQs) About Appliance Service
These are the ice maker questions owners ask us most.
How Long Does It Take a Sub-Zero Ice Maker to Start Making Ice?
After a repair or restart, plan on about 24 hours. That is how long the first full batch takes to reach the bin.
Is It Normal for My Undercounter Ice Maker Bin to Melt Ice?
Yes. These units let stored ice melt slowly while they make fresh ice. This keeps the cubes clear. Constant melting with no new ice is not normal.
Why Is My Sub-Zero Ice Maker Making Noise?
Filling, harvesting, and falling ice all make normal sounds. Grinding, loud buzzing, or clicking with no ice points to a pump, valve, or motor fault.
Should I Turn Off My Ice Maker If It Is Leaking?
Yes. Turn it off. Close the water supply valve. Wait until a tech can check it.
Do You Repair Outdoor Sub-Zero Ice Makers?
Yes. We fix outdoor-rated ice makers in patio bars and outdoor kitchens. Pollen, dust, and salt air clog the condenser fast. These units often need extra cleaning.
