Taste problems usually involve a new/old filter, stagnant water, non-approved tubing, household supply quality or an unflushed system. Check the filter date and part number against the manual. Draw several glasses and see whether the taste fades. Compare a glass from the tap and one from the fridge.

Common questions
How often should a refrigerator water filter be replaced?+
Follow your manual; a common interval is about six months, or sooner if flow drops or the taste changes.
Should I throw away the ice as well?+
Yes, if the water tasted bad. Ice absorbs odors from the water and the freezer, so empty the bin and let fresh batches form after the filter is changed and purged.
Why does the water taste bad?+
An old filter, stagnant water or tubing issues.
How do I improve the taste of the dispenser water?+
Replace the filter and flush the line.
Could the household water be the cause?+
Yes, taste your tap water to check.
How often should I replace the water filter?+
About every six months, or when the indicator says so, or sooner if water tastes or smells bad.
Why does the first glass taste bad after a new filter?+
Flush the new filter by running a few liters of water through it, as the manual says, to clear carbon dust and air.
Does old ice affect the water's taste?+
Ice absorbs odors, so empty and clean the ice bin, and replace the filter if the ice tastes off.
