How to Clean Nugget Ice Makers Under Counter in 7 Steps
1. Power Down & Empty the Unit
Safety first: Always unplug the ice maker before any maintenance to avoid electrical hazards.
– Remove any remaining ice from the bin and discard it.
– Shut off the water supply if applicable.
2. Remove & Wash Detachable Components
Take out removable parts such as:
– Ice basket
– Filter screens
– Drip trays
Soak them in warm, soapy water or a vinegar-water solution for at least 10–15 minutes. Use a soft brush or food-grade silicone scraper to clean off residues. Rinse and air dry thoroughly.
3. Internal Cleaning Cycle
Many nugget ice makers under counter like Scotsman, GE Profile and Icepure come with a self-cleaning cycle or Clean Mode.
– Fill the water reservoir with an FDA-approved ice machine cleaner or diluted vinegar.
– Activate the cleaning cycle per your model’s instructions. This flushes the internal tubing, evaporator, and pump system.
4. Tackle Hard Water Scale
For machines in hard water areas, lime scale is inevitable.
– Mix 1 part white vinegar with 3 parts warm water and pour it into the system.
– Let it sit for 30 minutes to dissolve stubborn deposits in the reservoir or lines.
– For severe buildup, repeat this step or use a commercial descaling solution recommended for the best nugget ice maker brands.
5. Disinfect Safely
After removing scale, disinfect internal surfaces using an NSF-certified sanitizing agent.
– Mix per label instructions (commonly 1 oz per gallon of water).
– Pour the solution into the reservoir and run a rinse cycle if available, or circulate it manually.
This eliminates mold, mildew, and bacterial residue.
6. Dry Thoroughly & Inspect
Let the machine sit with its door or lid open until fully air dried.
– Pay close attention to areas around the evaporator plate, vents, and tubing connections.
– Use a sterile microfiber cloth to wipe inaccessible spots dry.
7. Restart & Discard Initial Batches
Once dry, reassemble the parts, reconnect water, and plug the machine back in.
– Allow it to produce 3 batches of ice, then discard them to ensure any residual cleaning agents are flushed out.
