Symptoms
- Ice tastes distinctly metallic
- Taste is stronger in the first ice of the day
- Household water itself may also taste metallic
- Newer installation or recently serviced water line
Likely causes
- CommonOverdue or missing water filterFilters are designed to reduce metallic taste from minerals like iron; without one, taste comes through directly.
- CommonWater sitting in a copper supply line overnightWater that sits in copper pipe picks up a metallic taste, most noticeable in the first ice made after standing water.
- PossibleHigh iron or copper content in household waterSome water sources naturally have more dissolved metal, which filters can only partially reduce.
- Less commonNew fittings or valve components off-gassingRecently installed metal fittings can impart a taste for the first days of use.
What to do
- Install or replace the water filter if one isn't present or it's overdue.
- Discard the first couple of ice batches each morning if the line sits unused overnight.
- Taste your tap water directly to see if the metallic taste originates there rather than the fridge.
- If a fitting or line was recently replaced, flush several gallons through before judging taste.
- Consider a filter specifically rated for iron or metal reduction if your home has known hard or mineral-heavy water.
- If taste persists and is strong, have your water tested to rule out plumbing corrosion issues.
