How to Clean an Ice Maker: Step-by-Step Guide For Every Type

If your refreshing, ice-cold drinks are starting to taste a little off, perhaps your ice maker is due for a cleaning. Mineral deposits and bacteria can build up in the water lines over time and affect the way your drinks taste. But there’s good news. Cleaning an ice maker is an easy DIY task when you follow the simple steps outlined below. 

How to Clean an Undercounter Ice Maker 

An undercounter ice maker is built into your cabinetry and connects directly to your home’s water line. They’re great for large households or those that entertain often, producing up to 50 pounds of ice a day. But because they run continuously and connect to plumbing, they’re also prone to mineral buildup and mold. 

To clean your undercounter ice maker, follow these steps. 

1. Turn off the unit. Wait 10 minutes for any remaining ice in the cutting tray to drop into the bin.
2. Remove any remaining ice from the bin.
3. Take out any removable parts like the ice basket and scoop and wash them in warm, soapy water. Set them aside to dry. 
4. Drain the machine’s reservoir by opening the drain cap (if your model has one). Return the cap for the next step. 
5. Run a cleaning cycle using a commercial ice machine cleaner (per label directions) or a 1:10 vinegar and water solution. Pour it into the reservoir and run the unit’s cleaning cycle. If your model doesn’t have a cleaning cycle, let the solution sit for 10–15 minutes, then scrub the interior with a soft cloth or brush. 
6. When the cleaning cycle ends, remove the drain cap to empty the solution, then replace the cap. 
7. Rinse thoroughly if the cleaner requires it by running one or two cycles with clean water. Some food-safe cleaners don’t require this step. 
8. Return the removable parts. Turn on the unit and enjoy. 

How to Clean a Countertop Ice Maker 

A countertop (or portable) ice maker is smaller, lighter, and doesn’t need a direct water line. Instead, you fill them manually, making them popular for RVs, efficiency apartments, or outdoor kitchens. They’re also easier to drain and clean than larger units. Many models include a self-cleaning button and can make up to 50 pounds of ice, though you’ll need enough counter space to place them. 

To clean a countertop ice maker, follow these steps: 

1. Turn off the unit. Wait about 10 minutes for the remaining ice to drop into the bin. If frost has built up, let it melt before moving on. 
2. Remove any remaining ice from the bin. 
3. Take out all removable parts and wash them in warm, soapy water. Set them aside to dry. 
4. Drain the machine’s reservoir by opening the drain cap (if your model has one). Return the cap for the next step. 
5. Run a cleaning cycle with a commercial ice maker cleaner (per label directions) or a 1:10 vinegar and water solution. Pour it into the reservoir and start the cycle. If your model doesn’t have a cleaning function, run two or three regular cycles with the cleaning solution. Discard any ice that’s produced during this process. 
6. When the cleaning cycle ends, remove the drain cap to empty the solution, then replace the cap. 
7. Rinse thoroughly if the cleaner requires it by running one or two cycles with clean water. Some food-safe cleaners don’t require this step. If you used vinegar, run two extra rinse cycles to remove any lingering taste. 
8. Wipe the interior with a soft cloth or brush dipped in a baking soda solution, then follow with a clean, damp cloth to remove residue. 
9. Return the removable parts. Turn the unit back on and enjoy. 

How to Clean a Refrigerator’s Ice Maker 

Most refrigerators today include a built-in ice maker in the freezer compartment. If yours doesn’t, you can often add one at purchase. These ice makers connect directly to the home’s water line and your refrigerator’s water filtration system. They produce a moderate amount of ice. Cleaning them takes a little more effort because the ice maker is tucked inside the freezer with minimal room for working. 

To clean a refrigerator ice maker, follow these steps: 

1. Clear stored food from the freezer so you have space to work inside. 
2. Lift the control arm to turn off the ice maker. Remove the bin and discard or save the old ice. 
3. Wash the bin and scoop in warm, soapy water.  
4. Wipe the ice maker components and nearby freezer surfaces with a cloth dipped in a vinegar and water solution. 
5. If your fridge has a water filter that’s older than six months, replace it. Then run and discard the first few batches of ice to clear any cleaning solution. 
6. If needed, flush or replace the refrigerator’s water line to remove any microbial growth. *Only put removable parts in the dishwasher if the manufacturer states they’re dishwasher safe. 

Signs Your Ice Maker Needs Cleaning 

Regular ice maker cleaning not only eliminates off-tasting ice but also helps prevent breakdowns and extends your appliance’s lifespan. If you’re not sure when to clean your ice maker, watch for these signs: 

• Ice has an unpleasant taste or smell 
• The ice looks cloudy or has white spots 
• Ice cubes are smaller or irregularly shaped 
• Production has slowed down 
• You see mold or other debris inside the appliance 
• It’s been six months or more since you cleaned it 

Ice Maker Maintenance Tips and Other Considerations 

Regular upkeep goes a long way toward fresh, clean ice and a reliable appliance. To enjoy a steady stream of ice all year long, follow these tips: 

• Clean your ice maker every 6–9 months, or every 3–4 months if you have hard water. 
• Replace water filters about every 6 months, or sooner if you notice something off. Coordinating this with cleanings makes life easier. 
• Always use a clean, dedicated scoop–not your hands–to avoid contaminating your ice. 
• Keep the exterior and surrounding area clean and dry. 
• Store portable machines in a cool, dry spot when not in use. 
• If your unit has condenser coils, vacuum them monthly to improve efficiency. 

Ice makers make life easier, but they need regular TLC to keep delivering clean, fresh-tasting ice. Whether you own a built-in, countertop, or refrigerator model, regular cleaning and maintenance help your machine last longer and your drinks taste better. A simple cleaning routine keeps your ice crisp, clear, and ready whenever you need it.
