Four ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The filter, or the wrong filter
The most common cause by a distance. Check the part number against the model rather than against the last one bought.
-
Air in the line after a change
Draw off several liters. It usually clears on its own, and it is the reason a filter change so often makes things briefly worse.
-
Ice absorbing what is beside it
Ice is porous and does this readily. Empty the bin completely, cover anything open in the freezer, and let it make a fresh batch before judging.
-
A bin or drain that needs cleaning
Particularly on units that make ice slowly and let it sit. If taste comes with slow production or cloudy cubes, it has stopped being a filter question.

01
Empty the ice bin completely
Ice is porous and absorbs whatever is beside it. Let it make a fresh batch before judging anything, and cover anything open in the freezer.
-
02
Check the filter against the model
The wrong filter fitted is as common as a filter past its life. The part number belongs to the model, not to the last one bought.
-
03
Draw off several liters
Air in the line after a filter change usually clears this way, and it explains why a fresh filter so often makes the taste briefly worse.
-
04
Then book the visit if it comes with more
Taste alone is usually the filter. Taste with slow production, cloudy cubes or any sign of a leak has stopped being a filter question.

About Sub-Zero ice or water tastes off
The fastest diagnosis is the code
This one rarely produces a code, which is itself useful information: no code and a taste problem points at the water path rather than at the refrigeration.
What causes it
- A filter past its life, or the wrong filter fitted — the most common cause by a distance
- Air in the line after a filter change, which usually clears after a few liters are drawn off
- Ice absorbing odors from an open container in the freezer; ice is porous and does this readily
- A drain or bin that needs cleaning, particularly on units that make ice slowly and let it sit
When to call
If taste is accompanied by slow production, cloudy ice or any sign of a leak, it stops being a filter question. Those together usually mean the water path or the freeze cycle, and both are worth diagnosing rather than guessing.

Before you book
Questions about Sub-Zero ice or water tastes off
It started after a filter change.
Draw off several liters and empty the ice bin completely. Air in the line and a bin of old ice account for most of these.
Ice smells of the freezer.
Ice is porous and absorbs odors readily. An uncovered container in the freezer is the usual culprit, and a fresh batch after emptying the bin settles it.
When is it not a filter problem?
When taste comes with slow production, cloudy ice or any sign of a leak. That combination points at the water path or the freeze cycle.
