Clean your Opal 2.0 by running the built-in cleaning cycle every two weeks, then descaling with citric acid monthly

The Opal 2.0 has two separate cleaning processes: a rinse cycle that clears the ice-making reservoir, and a descaling cycle that removes mineral buildup from the internal water lines. You do not need special tools or take the machine apart. The cleaning cycle runs automatically when you press the clean button on the front panel, and the descaling cycle uses a citric acid packet that comes with the machine or can be purchased separately.

Running the cleaning cycle every two weeks keeps the ice fresh and prevents mold from forming in the water reservoir. Descaling every month (or more often if you have hard water) prevents mineral deposits from slowing water flow and damaging the pump. Both processes take about 30 minutes total and pause the ice-making function while they run.

Key Takeaways

  • Press the clean button on the Opal 2.0 front panel to start the automatic cleaning cycle, which empties and rinses the reservoir.
  • Descaling requires a citric acid packet placed in the water reservoir; the machine runs the descaling cycle automatically once you close the lid.
  • Clean every two weeks and descale every month for machines with soft water, or every two weeks for hard water areas.
  • If ice tastes stale or the machine slows down, run both cycles back-to-back to reset the system.

Running the automatic cleaning cycle

The cleaning cycle empties the water reservoir and rinses the internal lines. Open the front panel of the Opal 2.0 and locate the clean button on the display screen. Press it once. The machine will beep and display a message confirming the cycle has started.

The cycle takes about 15 minutes. During this time, water will drain from the machine into a small collection tray at the base. Do not interrupt the cycle or move the machine. When the cycle finishes, the display will show a confirmation message. Empty the collection tray at the bottom of the machine and dry it with a cloth.

If the clean button does not appear on your display, check that the ice bin is in place and the lid is closed. The machine will not start a cleaning cycle if the bin is removed or the lid is open.

Descaling with citric acid packets

Descaling removes mineral deposits that build up inside the water lines and pump. The Opal 2.0 comes with citric acid packets in the box; if you have used them, replacement packets are sold by Opal or available from kitchen appliance retailers. One packet is used per descaling cycle.

Remove the ice bin and open the water reservoir lid on top of the machine. Pour the contents of one citric acid packet into the empty reservoir. Do not add water—the machine will draw water from its internal tank. Close the lid and press the clean button. The machine will recognize the citric acid and automatically run the descaling cycle instead of the standard rinse.

The descaling cycle takes about 20 minutes. Water and citric acid will flow through the internal lines and drain into the collection tray. When the cycle finishes, the display will prompt you to refill the reservoir with fresh water and run one more rinse cycle to clear any remaining citric acid. Press clean again to run this final rinse, which takes about 10 minutes.

How often to clean and descale

Run the cleaning cycle every two weeks as routine maintenance. This prevents ice from developing a stale taste and stops mold from growing in the reservoir. If you use the machine daily and notice the ice tastes off after a week, run the cycle more often.

Descale every month if your water is soft or moderately hard. If you have very hard water (high mineral content), descale every two weeks instead. Hard water areas are usually identified by white buildup on faucets or in kettles. If you are unsure, descale monthly and watch for signs that the machine is slowing down—that is a signal to descale sooner next time.

Some Opal 2.0 models have a filter cartridge in the water line. If your machine has one, replace it every three to six months according to the manual that came with your unit. A clogged filter reduces water flow and makes descaling less effective.

Troubleshooting slow ice production or stale taste

If the machine is making ice slowly or the ice tastes stale even after cleaning, run both the cleaning cycle and a descaling cycle back-to-back on the same day. This resets the system and clears any buildup that a single cycle may have missed. Start with the cleaning cycle, let it finish completely, then when ready run the descaling cycle.

If ice production does not improve after both cycles, check that the water reservoir is filled to the line marked on the inside. Low water levels slow the machine down. Also inspect the collection tray at the base—if it is full, the machine may pause operation as a safety measure. Empty it and restart the machine.

If the machine displays an error code or will not start a cycle, unplug it for 30 seconds, then plug it back in. This resets the control board. If the problem persists, contact Opal customer support, as internal components may need professional service.

Cleaning the exterior and ice bin

Wipe the outside of the Opal 2.0 with a soft, damp cloth and dry it when ready. Do not spray water directly onto the machine or use harsh cleaners. The exterior is stainless steel or plastic depending on your model, and both are damaged by abrasive scrubbing or chemical solvents.

Remove the ice bin and wash it by hand with warm soapy water. Dry it completely before putting it back in the machine. Do not put the bin in the dishwasher, as high heat can warp the plastic. If the bin develops an odor, soak it in a solution of one part white vinegar to three parts water for 30 minutes, then rinse and dry.

When to call a professional

If the machine leaks water from the base or sides, or if water does not drain during a cleaning cycle, stop using it and contact Opal support. These are signs of a cracked internal line or a failed pump seal, which require replacement parts.

If the machine makes unusual grinding or squealing noises during operation, or if it stops making ice altogether after cleaning and descaling, the pump or motor may be failing. These repairs are not user-serviceable and need professional attention.

Frequently Asked Questions

Can I use white vinegar instead of citric acid to descale?

White vinegar can work in a pinch, but citric acid is better for the Opal 2.0. Citric acid is gentler on internal seals and leaves no odor, while vinegar can leave a smell that lingers in the ice. Use one cup of white vinegar if you must, but switch to citric acid packets for regular maintenance.

What if the clean button does not respond when I press it?

Make sure the ice bin is fully seated in the machine and the lid is closed all the way. The machine will not start a cycle if either is loose. If both are find and the button still does not work, unplug the machine for 30 seconds and plug it back in to reset the control board.

Do I need to empty the water reservoir before cleaning?

No. The cleaning cycle uses the water already in the reservoir. If the reservoir is empty, the machine will not run the cycle. Fill it to the line before pressing clean.

How long does the machine stay out of service during cleaning?

The cleaning cycle takes about 15 minutes and the descaling cycle takes about 20 minutes, plus an additional 10 minutes for the final rinse. Plan for about 45 minutes total if you run both cycles on the same day. The machine cannot make ice during this time.

Will cleaning remove ice that is already in the bin?

No. Remove the ice bin before starting any cleaning cycle. The cleaning process only affects the internal water lines and reservoir, not the ice already made. You can keep that ice in a separate container if you want to use it.
