Clean the ice maker monthly to prevent mineral buildup and keep nuggets tasting fresh

Your Frigidaire Gallery nugget ice maker needs cleaning about once a month, or more often if you have hard water. The process takes roughly 30 minutes and involves running a cleaning cycle with a commercial ice machine cleaner, then flushing the system with water. You do not need to take the machine apart—Frigidaire built the cleaning steps into the appliance itself.

Mineral deposits and mold can build up inside the water lines and ice-making chamber even if the water looks clean. This makes the ice taste off, slows ice production, or causes the machine to stop working. Cleaning prevents all three problems and extends the life of your machine by years.

Key Takeaways

  • Run a cleaning cycle using Affresh Ice Machine Cleaner or a similar commercial product designed for nugget ice makers—do not use vinegar or household cleaners.
  • The cleaning cycle takes about 15 minutes; you then run two water-only cycles to rinse, which takes another 15 minutes.
  • Turn off the ice maker and let it sit for 30 minutes before you start, so the cleaning solution works on existing buildup.
  • If your ice maker stops producing ice or the nuggets taste metallic or stale, cleaning is usually the first fix to try.

What you need before you start

Gather these items before you begin: a bottle of Affresh Ice Machine Cleaner (the most common choice for Frigidaire machines), a large bowl or pitcher to catch water during the rinse cycles, and a clean cloth or sponge. Affresh comes in a small bottle and costs around $8 to $12; you can find it at most grocery stores, big-box retailers, or online. Do not substitute vinegar, lemon juice, or other household cleaners—they are not formulated for ice machine parts and can leave residue or damage seals.

Check your ice maker's water filter while you have the machine open. If it looks discolored or you have not changed it in six months, replace it now. A clogged filter reduces water flow and forces the machine to work harder, which speeds up mineral buildup.

Turn off the machine and let it rest

Press the power button on your Frigidaire Gallery ice maker to turn it off. Wait 30 minutes. This pause lets any remaining ice melt and allows mineral deposits inside the lines to soften, so the cleaning solution works more effectively.

While you wait, wipe down the outside of the machine and the ice bin with a damp cloth. Remove any loose ice from the bin and discard it. This is also a good time to check that the drain line at the back of the machine is not kinked or blocked.

Run the cleaning cycle with Affresh

Open the cleaning access panel on your ice maker. On most Frigidaire Gallery models, this is a small door or removable cover on the front or side of the machine—check your manual if you cannot locate it. Pour the entire bottle of Affresh into the water reservoir or cleaning port, following the instructions on the bottle.

Close the access panel and turn the machine back on. Press the cleaning or service button (the exact name varies by model; your manual will show which button to use). The machine will run a cleaning cycle that lasts about 15 minutes. You will hear water flowing and the ice-making mechanism working. Do not interrupt this cycle—let it run to completion.

Water mixed with cleaner will drain out of the machine during this cycle. Place your bowl or pitcher under the drain outlet to catch it, or let it flow into a sink if your machine is positioned near one. The water may be cloudy or discolored; this is normal and shows the cleaner is working.

Rinse the system twice with water only

Once the cleaning cycle finishes, the machine will stop. Wait a few minutes, then press the cleaning button again to start a rinse cycle using only water. This cycle also lasts about 15 minutes and flushes out the cleaning solution. Again, water will drain from the outlet—catch it or let it run into a sink.

When the first rinse cycle finishes, repeat the process one more time: wait a few minutes, then start a second water-only rinse cycle. Two rinses remove nearly all the cleaner residue. If you skip this step or do only one rinse, the ice may taste soapy or bitter for the first few batches.

Make and discard the first batch of ice

After the second rinse cycle finishes, turn the machine back on normally (not in cleaning mode). The machine will begin making ice. Let it run for 30 minutes to an hour, then empty the ice bin and discard all the ice. This first batch may still contain trace amounts of cleaner or loosened mineral particles.

After you discard the first batch, the ice maker is ready to use. The nuggets should taste fresh and the machine should run quietly. If you notice the ice still tastes off, run one more water-only cycle and discard another batch.

Common mistakes that slow down cleaning

The most frequent error is using vinegar instead of commercial cleaner. Vinegar is acidic but not formulated for ice machine seals and water lines—it can leave a vinegar taste in the ice for weeks and may damage rubber gaskets over time. Stick with Affresh or a cleaner made specifically for ice machines.

Another mistake is skipping the 30-minute rest period at the start. If you turn off the machine and when ready start the cleaning cycle, the solution does not have time to soften buildup, so the cleaning is less effective. The 30 minutes is worth the wait.

Running only one rinse cycle instead of two is also common. One rinse leaves cleaner residue behind, which affects the taste of the ice. Two full water-only cycles are necessary to flush the system completely.

When to clean more often

If you have hard water (water with high mineral content), clean your ice maker every two weeks instead of monthly. Hard water leaves deposits much faster than soft water. You can tell you have hard water if you see white or chalky buildup on faucets or inside kettles.

If the ice maker is in a very warm kitchen or gets heavy use (making ice constantly), increase cleaning to every three weeks. Heat and constant operation speed up mineral accumulation. If you notice the ice production slowing down or the nuggets becoming smaller, that is a sign to clean sooner rather than waiting for the next scheduled date.

Frequently Asked Questions

Can I use vinegar to clean my Frigidaire nugget ice maker?

No. Vinegar is not formulated for ice machine seals and can leave a vinegar taste in the ice for weeks. Use Affresh Ice Machine Cleaner or another commercial product made for ice makers. These are designed to dissolve mineral deposits without damaging the machine's internal parts.

What if my ice maker stops making ice after cleaning?

Make sure you ran both rinse cycles completely and discarded the first batch of ice. If the machine still does not make ice, turn it off, wait 10 minutes, and turn it back on. If it still does not work, check that the water line is connected and not frozen, and that the water filter is not clogged. If none of these fix it, contact Frigidaire support.

How long does the entire cleaning process take?

About 60 to 90 minutes from start to finish. The cleaning cycle is 15 minutes, each rinse cycle is 15 minutes, and waiting for the first batch of ice takes 30 to 60 minutes. You can do other things while the machine runs—you do not need to stand and watch it.

Do I need to replace the water filter when I clean the ice maker?

Not every time, but check it during each cleaning. If the filter looks dark, discolored, or you have not changed it in six months, replace it now. A fresh filter improves water quality and reduces the buildup that makes cleaning necessary more often.

What if the ice still tastes bad after cleaning?

Run one more water-only cycle and discard another batch of ice. Sometimes trace cleaner or loosened particles remain after two rinses. If the taste does not improve after a third rinse and fresh batch, the issue may be the water source itself—check that your water line is clean and consider replacing the water filter.
