Clean your Opal ice maker every month by running the cleaning cycle, wiping the ice basket and chute, and descaling the water tank

Opal ice makers need regular cleaning to keep ice tasting fresh and the machine running smoothly. The good news is that Opal built a cleaning cycle into the machine itself—you do not need special tools or harsh chemicals. A monthly cleaning takes about 30 minutes and involves running the machine's own cleaning program, then wiping down the parts you can reach by hand.

The machine will tell you when cleaning is due. Most Opal models display a "Clean" message on the screen after 30 days of use, though you can clean more often if you notice ice smells stale or the machine is running slower than usual. Hard water buildup is the most common reason an Opal slows down, and cleaning fixes it.

Key Takeaways

  • Run the cleaning cycle through the machine's menu once a month, which takes about 15 minutes and uses a cleaning solution Opal sells separately.
  • After the cycle finishes, empty the ice basket, wipe it dry, and clean the ice chute with a soft cloth to remove any mineral deposits.
  • Descale the water tank every three months by soaking it in white vinegar or using Opal's descaling solution to prevent hard water buildup.
  • Never use bleach, vinegar, or abrasive scrubbers inside the machine itself—only use Opal's approved cleaning solution in the cleaning cycle.
  • If the machine stops making ice or makes less ice than usual, a cleaning cycle often solves the problem before you call for service.

Running the Opal cleaning cycle

The cleaning cycle is built into your Opal machine and takes about 15 minutes. To start it, you will need Opal's cleaning solution, which comes in small bottles and is sold separately (check the Opal website or Amazon for the correct model). Do not use vinegar or other household cleaners in the machine—they can damage the internal parts.

Press the menu button on your Opal's screen and scroll to "Settings" or "Maintenance," depending on your model. Select "Cleaning Cycle" and follow the on-screen prompts. The machine will ask you to pour the cleaning solution into the water tank. Fill it to the line marked on the tank, then close the tank and press start. The machine will run water and cleaning solution through all the internal parts. You will hear the pump working and see water drain into the collection tray below. Let it run without interrupting it.

When the cycle finishes, the screen will show a message like "Cleaning Complete" or return to the home screen. Empty the collection tray (it will have dirty water in it) and pour it down the sink. Do not drink any water or ice made during the cleaning cycle.

Cleaning the ice basket and chute

After the cleaning cycle finishes, remove the ice basket from the front of the machine. It slides out easily—just pull it straight toward you. Empty any ice into the sink and rinse the basket under warm running water. Use a soft cloth or sponge to wipe the inside and outside of the basket, paying attention to the corners where mineral deposits can build up. Dry it completely with a clean towel before sliding it back in.

Next, look at the ice chute—the opening where ice falls into the basket. You may see white or cloudy buildup on the walls of the chute. This is mineral deposit from hard water and is normal. Dampen a soft cloth with warm water and gently wipe the inside walls of the chute. Do not use a brush or scraper, which can scratch the plastic. If the buildup is stubborn, dampen the cloth with a 50/50 mix of white vinegar and water, wipe it on, let it sit for two minutes, then wipe it clean with a dry cloth.

Wipe down the outside of the machine with a damp cloth as well. Pay attention to the screen and any vents on the sides or back. Dry everything with a clean towel when you are done.

Descaling the water tank every three months

The water tank is where hard water minerals build up most. Even if you run the cleaning cycle monthly, descaling the tank separately every three months keeps the machine working at full speed. You can use either Opal's descaling solution or white vinegar—both work well.

Remove the water tank by opening the top of the machine and lifting it straight out. Empty any remaining water. If you are using white vinegar, fill the tank halfway with white vinegar and halfway with distilled water. If you are using Opal's descaling solution, follow the bottle's instructions for how much to use. Close the tank and let it sit for 30 minutes. The vinegar or solution will dissolve mineral buildup inside.

After 30 minutes, empty the tank into the sink. Rinse it thoroughly under running water, rubbing the inside with your fingers to loosen any remaining deposits. Rinse it at least three times until the water runs clear and you smell no vinegar. Fill it with fresh distilled water, close it, and put it back in the machine. Run one cycle of ice to flush out any remaining vinegar taste, then throw away that batch of ice.

What to do if the machine stops making ice

If your Opal suddenly makes no ice or makes much less than usual, a cleaning cycle is the first thing to try before calling for service. Hard water buildup inside the machine can block the water flow, and the cleaning cycle clears it out. Run the full cleaning cycle as described above, then wait 24 hours and see if the machine makes ice normally again.

If cleaning does not fix the problem, check that the water tank is full and that the machine is plugged in. Make sure the collection tray underneath is not overflowing—if it is full, the machine will stop making ice as a safety feature. Empty the tray and try again. If the machine still does not make ice after cleaning, a water line may be frozen or blocked, and you will need to contact Opal support.

Common mistakes to avoid

The most common mistake is using the wrong cleaning solution. Opal sells a specific cleaning solution for its machines. Do not use vinegar, bleach, or all-purpose cleaners in the cleaning cycle itself—these can damage the pump and water lines. Vinegar is safe only for soaking the water tank separately, not for running through the machine.

Another mistake is not letting the machine dry completely after cleaning. If you put the ice basket back in while it is still wet, water can pool and freeze in the wrong places, blocking the chute. Always dry the basket and chute with a clean towel before using the machine again.

Finally, do not skip the cleaning cycle just because the machine still makes ice. Mineral buildup happens slowly, and by the time you notice the machine is slow, deposits have already built up inside. Cleaning monthly prevents that slowdown and keeps your ice tasting fresh.

Frequently Asked Questions

How often should I clean my Opal ice maker?

Run the cleaning cycle once a month, or whenever the machine displays a "Clean" message on the screen. If you have very hard water, you may want to clean every two weeks. Descale the water tank separately every three months.

Can I use vinegar in the cleaning cycle?

No. Use only Opal's approved cleaning solution in the cleaning cycle—vinegar can damage the internal pump. You can use vinegar to soak the water tank separately, but never pour it into the machine's cleaning cycle.

What if my ice tastes bad or smells stale?

Run the cleaning cycle and descale the water tank. Stale-tasting ice usually means mineral buildup or bacteria growing in the tank. After cleaning, throw away the first few batches of ice the machine makes. If the taste does not improve after cleaning, the water you are using may have a strong mineral or chlorine taste—try using distilled water in the tank instead.

Do I need to turn off the machine before cleaning?

Yes. Turn off the machine and unplug it before removing the water tank or ice basket. The cleaning cycle itself will guide you through the process, so you do not need to turn it off for that—just follow the on-screen prompts.

What is the white buildup on the ice chute?

That is mineral deposit from hard water, usually calcium and magnesium. It is harmless but can slow down ice production if it builds up too much. Wipe it away with a damp cloth during your monthly cleaning, or use a vinegar-and-water solution if it is stubborn.
