Quick answer

If your ice maker smells like fish, the ice has most likely soaked up odors from a dirty bin, stale water in the line, or a water filter that is past its date. Throw out the old ice, wash and dry the bin, swap the filter and run the cleaning steps in your manual. An ice maker cleaner reaches the scale and film inside the machine that a wipe cannot, which is why the smell stays gone.

Free fix vs. permanent fix

Free fix · 30 minutes plus drying

Dump, wash and dry the bin

  • Switch off the ice maker and throw out all the ice
  • Wash the bin with warm water and a drop of dish soap
  • Rinse well and dry it completely before refitting
  • Throw out the first two or three batches of new ice

How long it lasts: A few weeks to a few months if the smell lived in the bin or the ice. If it comes from inside the machine, it returns.

An ice maker cleaner, plus a fresh filter

Film and mineral scale build up in the tray and water line, where a cloth cannot reach. A cleaner made for ice makers dissolves them, and a fresh filter stops stale water from starting the cycle again.

What to get: Ice maker cleaner solution

How long it lasts: Several months at a time, if you repeat the clean every six months and swap the filter on schedule.

Why it happens

1

Old ice absorbing freezer odors

Ice soaks up smells from fish, onions and open food nearby. Cubes that sit for weeks taste and smell stale.

2

A dirty ice bin or tray

Melt water leaves a film in the bottom of the bin. Mold and mildew grow in it and give off a sour or musty smell.

3

A water filter that is past its date

Filters only trap sediment and chlorine taste for so long. Makers usually say to change them about every six months. An old one can leave water with a stale smell.

4

Scale and film in the water line

Minerals and slime build up where you cannot wipe. Hard water speeds this up.

5

New parts that off-gas

A new filter or new water line can smell like plastic or chemicals for the first few batches of ice.

Do these in order, starting with the simplest.

  1. Switch off the ice maker and empty the bin

    Turn it off with the arm or power switch, as your manual describes, then throw out all the ice, including any that has frozen into a block.

  2. Wash the bin

    Tool used: Dish soap and a soft sponge

    Use warm water with a drop of dish soap and a soft sponge. A soft brush helps with film in the corners. Rinse well and let it air dry.

  3. Wipe the ice compartment

    Tool used: Dish soap and a soft sponge

    Wipe the tray, chute and walls with a cloth dampened in warm soapy water, then wipe again with clean water. Dry everything before you turn the machine back on.

  4. Swap the water filter

    Tool used: Replacement water filter

    Fit a filter that matches your model number, then flush it as the instructions say, usually a few gallons through the dispenser.

  5. Run the cleaning cycle

    Tool used: Ice maker cleaner

    Follow your manual's method, or the cleaner label if the manual allows it, then rinse. Throw away the first two or three batches of ice.

  6. Freshen the freezer

    Tool used: Baking soda

    Leave an open box of baking soda in the freezer and replace it every month or two. It stops food odors from reaching the new ice.

When free fixes aren't enough

Washing the bin only helps when the smell lives in the bin. If it returns within a week or two, the film is inside the tray, the water line or the fill tube, where you cannot wipe. An ice maker cleaner is made to reach those spots, and a fresh filter keeps stale water from restarting it. A sharp, hot or burnt-fishy smell that comes from the back or bottom of the appliance, not from the ice, is a different problem. Overheating electrical parts can smell like that, so unplug the unit and call a technician.

Ice maker smells weird? Match the smell to the likely cause

  • Fish or stale: old ice, a dirty bin or an old filter.
  • Musty or sour: a damp bin or film in the tray.
  • Plastic or chemical: a new filter or line that needs flushing.
  • Hot or burnt, from the back of the unit: unplug and call a technician.

Ice maker smells like mold, mildew or musty? Where to look

Look for dark specks or slime in the corners of the bin and along the tray edge. Wash them away with warm soapy water and dry the bin fully, since damp plastic brings the smell back. On a countertop machine, empty the water reservoir every day or two. If you see black growth inside the water line or the ice looks dirty, stop using the ice and call for service.

What to skip

Scented sprays and strong chemicals

A spray near the ice bin only adds a second smell, and ice can absorb the fragrance too. Do not put bleach or strong cleaners in the machine unless your manual names them, because residue ends up in your ice.

Frequently asked questions

Why does my ice maker smell like fish?
Usually it is stale ice, a dirty bin, an old filter, or film in the water line. A fishy smell from the appliance itself, not the ice, can also mean overheating electrical parts. Unplug it and call a technician if the smell is hot, sharp or burnt.
Why does my ice maker smell bad?
Ice absorbs odors from the freezer and from a dirty bin. Throw out the old ice, wash the bin, and keep strong foods sealed. If it still smells bad a week later, swap the filter and clean the machine.
Why does my ice maker smell like chemicals?
A new filter or water line often smells like plastic or chemicals at first. Flush the filter as instructed and throw away the first two or three batches of ice. If the smell lingers after a week, check that no cleaner is left in the machine.
How often should I clean an ice maker?
Many makers suggest about every six months, and more often with hard water or heavy use. Swap the water filter on the same schedule.
