Refrigerator dispenser water tastes or smells bad

Off-tasting water from the dispenser is almost always caused by an old filter or standing water sitting in the line rather than a mechanical fault. Replacing the filter and flushing the line usually clears it up quickly.

Symptoms

  • Water tastes stale, plastic-like, or metallic
  • Water has a faint musty or off smell
  • Taste is worse after the fridge hasn't been used for a while
  • Ice made from the dispenser also tastes or smells off

Likely causes

  • CommonOverdue or expired water filterFilters lose effectiveness over time and can even start contributing to taste issues once saturated.
  • CommonStagnant water sitting in the line after infrequent useWater sitting unused in the tubing for days can develop a flat or off taste.
  • CommonNew filter needing an initial flushCarbon dust from a brand new filter can affect the first several cups of water.
  • PossibleHousehold water supply itself has a taste issueIf tap water also tastes off, the fridge filter isn't the cause.

What to do

  1. Check the filter replacement date and swap it out if it's overdue, typically every 6 months.
  2. After installing a new filter, run several cups of water through and discard them to flush out carbon dust.
  3. If the fridge hasn't dispensed water in a while, run a few cups through and discard them to clear out any stagnant water.
  4. Taste your regular tap water separately to rule out a general household water taste issue unrelated to the fridge.
  5. Clean the dispenser nozzle and drip tray, since buildup there can occasionally affect taste or smell.
  6. Check that the water filter is a genuine or compatible replacement, since poor-quality filters can affect taste.
  7. If taste issues continue with a fresh filter and flushed line, consider having the water line and inlet valve inspected.

When to call a pro

If a fresh filter and flushed line don't resolve the taste issue and tap water tastes fine, a technician can inspect the water line and inlet valve for contamination sources.
