Sub Zero 7012333 UC-15 Ice Maker Water Filter

The Sub-Zero 7012333 UC-15 Ice Maker Water Filter is made specifically for compatible UC-15 undercounter ice makers. It filters the water before it enters the ice-making system, helping reduce chlorine taste and odor, sediment, lead, and other unwanted contaminants that can affect the quality of your ice. The 7012333 has also been updated to part number 7042803, which fits the same UC-15 systems.

Specifications

Made for the UC-15 Ice Maker

The 7012333 is not a standard Sub-Zero refrigerator water filter. It is designed specifically for the UC-15 undercounter ice maker, using a dedicated filter housing and connection. That distinction matters because the water filters used in full-size Sub-Zero refrigerators are not interchangeable with the UC-15 system.

Cleaner-Tasting Ice

Water quality has a direct effect on the ice your machine produces. The activated carbon block helps reduce chlorine taste and odor, sediment, lead, and other contaminants before the water reaches the ice-making cycle, helping your ice taste cleaner and fresher.

Helps Reduce Scale

The filter also helps reduce scale-forming minerals before they enter the ice maker. Keeping these minerals under control can help maintain the internal water system and support consistent ice-making performance over time.

7012333 or 7042803?

Sub-Zero updated the original 7012333 part number to 7042803. The updated number refers to the same UC-15 filter, with the change reflecting the newer part number and packaging rather than a different filter design. Both numbers fit the compatible UC-15 ice maker models.

If your existing cartridge shows 7012333 or 7042803, you can use the corresponding replacement for the same UC-15 filter housing.

Up to 300 Gallons

The filter is rated for up to 300 gallons or six months, whichever comes first. Homes or businesses that produce a high volume of ice may reach the gallon limit sooner, so actual replacement timing can vary with usage and water quality.

Quick Twist-In Installation

The Sub Zero 7012333 uses a twist-in connection designed for straightforward replacement. No special tools or plumbing work are needed, making it easier to keep your UC-15 filter changed on schedule.

Built for Sub-Zero UC-15 Ice Makers

This filter is designed for the UC-15 family, including UC-15, UC-15I, UC-15IO, UC-15IP, UC-151, and UC-151P models. It is also listed as compatible with several Manitowoc ice makers that use corresponding filter part numbers.

Before ordering, check the model number of your ice maker or the part number printed on your existing filter. If you have a full-size Sub-Zero refrigerator rather than a UC-15 undercounter ice maker, this is not the correct filter for that appliance.
