Ice takes on whatever is in the water and whatever is in the air around it. Clean water, a current filter and a clean bin give ice with no taste at all, so any taste has a source. The most common in a business is a cleaning schedule that slipped: slime and mold grow in the sump, on the curtain and in the bin, and they give a musty or earthy taste long before anyone sees them. A filter past its date lets chlorine and minerals through. A cleaner or sanitizer that was not rinsed as the manual says leaves a chemical taste, as does one used in the wrong strength. Ice held too long in a bin that is rarely emptied goes stale and picks up odors, especially from food stored nearby or from a drain without an air gap that lets sewer gas and backflow into the bin. New water lines and new filters can also give a plastic or carbon taste for the first days. Ice is food, so a taste is treated as a hygiene question first. The 6 causes, cheapest first Answer these first 01 Is the taste musty, chemical, like chlorine, metallic, stale, or like food? 02 When were the machine and the bin last cleaned and sanitized, and when was the filter last changed? 03 Does the bin have a smell of its own when opened, and is any film visible on the curtain or the bin walls? 04 Is food, cleaning product or anything strong-smelling stored near the bin? 05 Does the bin drain run into a floor drain with an air gap, or is the hose pushed into the drain? ## Check these before you book. Ice machine ice tastes bad: 5 checks, and none of them costs anything. 01 Stop serving the ice if the taste is musty or chemical, and empty the bin. 02 Look at the curtain, the bin walls and the drain for pink or black film, without removing any panel. 03 Check the filter cartridge date and the date of the last clean and sanitize. ### Also worth checking - Look at where the bin drain ends: there should be an open gap between the hose and the floor drain. - If cleaning is due, run the maker's clean and sanitize cycle with the approved products exactly as the manual directs, or book it. ### How soon does it need a visit? Ice is food. A musty, chemical or sewer taste means the ice is not served until the machine is cleaned and the source found; a stale taste from ice held too long can be fixed by emptying the bin. ## The causes, cheapest first. 6 things ice from the ice machine tastes stale, chemical or musty turns out to be, from ice held too long, or food stored nearby to a problem in the building's water. [The cost guide](https://icemachinerepair.center/cost/) 1. 01 no repair ### Ice held too long, or food stored nearby Ice absorbs odors from the air in the bin and the room. Emptying and refilling the bin regularly and moving strong-smelling items away removes the taste. No repair: check it yourself 2. 02 no repair ### Cleaner or sanitizer not fully rinsed A chemical taste right after cleaning usually means the manual's rinse steps were cut short. Discard the first harvests after cleaning as the manual directs. No repair: check it yourself [See slime or mold growing in the ice machine bin](https://icemachinerepair.center/problems/ice-machine-slime-or-mold-in-bin/) 3. 03 lowest ### A filter past its date A spent filter lets chlorine, minerals and earthy tastes through.

The rinse steps in the manual were likely cut short, or the product was mixed stronger than directed. Discard the first harvests and follow the manual's rinse exactly. ### Can a dirty ice machine make people sick? Slime and mold in an ice machine are a hygiene risk. That is why makers and health inspectors set a cleaning and sanitizing schedule. ### The ice tastes musty but the bin looks clean. How? Growth often starts in the sump, the curtain and the tube before it reaches the bin. A full clean on the maker's schedule covers the parts you do not see. ### Does the bin drain affect the taste of the ice? It can. A drain without an air gap lets drain odors, or water in a backup, reach the bin. The hose should end above the floor drain, not inside it. --- **[Read on the site: Ice From the Ice Machine Tastes Stale, Chemical or Musty: Causes and Fixes](https://icemachinerepair.center/problems/ice-machine-ice-bad-taste-or-smell/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
