What REPLACE FILTER
actually means.
The UC-15I counts ice-making cycles, and after 8,000 it lights REPLACE FILTER in red. The reminder is a count, not a test of the filter; Sub-Zero also wants the filter changed every six months, after a long shutdown or when cubes turn hollow, whichever comes first.

What to do when REPLACE FILTER shows on the ice machineKind of codeMode, not a failure
Nothing is broken; the control is reporting a state someone chose or a routine it runs: a clean or sanitize reminder counting the hours since the last cycle, a delay of a few minutes after power returns before the pump and compressor start, a bin-full light while the bin control is satisfied, or a standby or off mode someone chose at the keypad. No part is needed; finishing the cycle the light asks for, waiting out the delay or the key sequence from the manual ends it.
Usually leads toNo repair
Turn the machine off with POWER and remove the ice from the bin.
Shows up asIce Machine Error Code or Flashing Light: What It Is Telling You
An ice machine error code may show as a number on a small display, a pattern of blinking lights on the control board, a colored light on the front, or a machine that stops with one indicator flashing.

Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for REPLACE FILTER on its ice machines. Follow it to the end: the last card says whether this is a visit.
Turn the machine off with POWER and remove the ice from the bin.
Remove the old cartridge with a quarter turn to the left, seat the new one with a quarter turn to the right, then run the short on-off sequence from the guide.
Touch and hold CLEAN for six seconds to clear the light; if it will not clear, book a visit.
Cleared?
The light or code is gone, and the machine fills, freezes and drops a full batch of cubes into the bin with no new part. If it returns within a week, or the clean light comes back straight after a cleaning cycle, mention that in the booking.
What not to do
REPLACE FILTER does not stop the machine; it keeps making ice while the light is on. Low ice with the light off can still be a clogged filter, since the count does not measure how dirty it is.

In Sub-Zero's own words
When the unit completes 8000 ice making cycles, “REPLACE FILTER” will illuminate red to indicate the water filter needs to be replaced.

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
