# 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.

Filter, line or drain

What it usually means

Started after a filter change

Ice smells of whatever is in the freezer

Water tastes flat rather than wrong

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.

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.

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.

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.

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.

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.
