The short answer: To set up your GE Profile Opal Ultra, place it on a level surface away from heat, install the water line or fill the reservoir, prime the water system, run a cleaning cycle, and then make ice. The process takes about 15 minutes, and you’ll be enjoying soft, chewable nugget ice shortly after. Here’s the detailed breakdown.
When your Opal Ultra arrives, unbox it carefully. The box includes the ice maker unit, a removable ice basket, an ice scoop, a water reservoir (if you didn’t get the direct water line version), and a quick start guide. Do not plug it in immediately after moving it; let it sit upright for at least 2 hours if it was tilted during transport. This lets the refrigerant settle. Inspect the unit for any visible damage, and keep all packaging until you’re sure it works.
Placement is crucial. Set the ice maker on a sturdy, level countertop. It weighs about 50 pounds when empty, so ensure the surface can support it. Keep at least 4 inches of clearance on all sides for airflow. Avoid placing it near the oven, dishwasher, or direct sunlight, as heat can affect performance. The Opal Ultra has a stainless steel front, so wipe it with a soft cloth to remove fingerprints. If you have the version with a water line, you’ll need to connect it to a cold water supply under the sink. If you’re using the reservoir, position it near a sink or water source for easy filling.
Before making ice, you must prime the water system to remove air and ensure proper flow. If you have the reservoir model, fill it with cold, filtered water up to the MAX line. If you have the direct water line model, open the water shutoff valve and check for leaks. Then, press and hold the ‘Clean’ button for 3 seconds to start the priming cycle. The pump will run, and you’ll see water circulating. Let it run for about 3 minutes, then press the ‘Power’ button to stop. This step is essential to avoid dry-running the pump, which can damage it. If the pump is noisy or doesn’t pull water, double-check the water source.
After priming, run a cleaning cycle to ensure the internal lines are clean. Mix a cleaning solution: use 2 cups of water and 2 tablespoons of white vinegar (or GE’s recommended cleaner). Pour this into the reservoir (for reservoir models) or into the cleaning port (for water line models). Press the ‘Clean’ button once to start the cycle. The unit will circulate the solution for about 10 minutes, then automatically drain. After it finishes, wipe down the interior with a soft cloth. Rinse the reservoir with clean water and run a quick rinse cycle by filling with fresh water and running a short ‘Clean’ cycle again. This ensures no vinegar taste remains.
Now you’re ready to make ice. Press the ‘Power’ button. The display will show the default settings. You can adjust the ice size using the ‘Small’ or ‘Large’ button: small nuggets for cocktails, large for crunchier ice. The Opal Ultra has a self-cleaning feature, but you can also set a schedule. The ice maker takes about 20 minutes to produce the first batch, which may be small or slightly misshapen; discard that first batch to ensure quality. The basket holds about 3 pounds of ice. The ‘Ice Full’ sensor will stop production when the basket is full. To keep your ice fresh, use the ‘Turbo’ mode if you need a large quantity quickly, but note it uses more energy.
Regular maintenance extends the life of your Opal Ultra. Clean the condenser coils every 6 months with a vacuum or brush. Replace the water filter every 3-6 months if you have the water line model. If you notice the ice is cloudy or has a smell, clean the unit more frequently. Common issues: if the unit stops making ice, check if the water reservoir is empty or if the ice basket is full. If the pump makes a whining noise, there might be air in the line; run the priming cycle again. If the display shows ‘Add Water’, fill the reservoir. Remember to unplug the unit when cleaning or if you’ll be away for more than a few days. For more detailed comparisons and buying tips, check out this guide to the best ice makers.
Before you commit to a spot, measure your available counter space. The Opal Ultra is a substantial appliance, and many owners report that it takes up more room than they expected. According to manufacturer specifications, the unit is roughly 10 inches wide, 17 inches deep, and 16 inches tall. That depth is important: it needs to sit far enough forward that the top vents are not blocked by an upper cabinet. If you have standard 18-inch deep counters, the machine will protrude slightly, which is normal. Also consider the height of your cabinets. You need at least 4 inches of clearance above the unit for hot air to escape. If you plan to place it under a cabinet, make sure there is a gap. Some owners place it on a sturdy cart or a dedicated stand to keep it accessible. Weight is another factor: when full of water and ice, the Opal Ultra can weigh over 60 pounds. Make sure your shelf or counter can handle that load without sagging. If you have a water line model, you will also need a nearby cold water supply, typically under the sink, and enough tubing to reach the unit without kinking. Measure the distance from the water valve to the intended location and add a few extra feet for slack. If you are renting or cannot install a water line, the reservoir model is the better choice, but you will need to refill it manually, so keep it close to a sink. Finally, think about noise. Nugget ice makers are not silent. The compressor and auger produce a hum that some find noticeable in open-plan living spaces. If your kitchen is adjacent to a TV room, you may want to place the unit on a vibration-absorbing mat to reduce noise transfer. Planning the location carefully now will save you from moving a heavy, water-filled appliance later.
To keep your Opal Ultra running well, follow a simple maintenance routine. Every week, empty and rinse the ice basket and reservoir with warm water. Every month, run a cleaning cycle with a descaling solution or a vinegar mix as described earlier. Every 3 to 6 months, replace the water filter if you have a water line model, or more often if your water is hard. Every 6 months, vacuum the condenser coils at the back or bottom of the unit. Dusty coils make the compressor work harder and can shorten its life. Also check the water line connections for leaks and tighten if needed. Common mistakes that new owners make include: not priming the pump before first use, which can damage it; using unfiltered tap water, which leads to scale and cloudy ice; placing the unit in direct sunlight or next to a heat source, which reduces ice production; overfilling the reservoir past the MAX line, which can cause leaks; and ignoring the ‘Clean’ reminder light. Another mistake is not leveling the unit. If the ice maker is not level, water may not flow correctly, and the ice may come out wet or misshapen. Use a spirit level to check and adjust the feet if necessary. Some owners also forget to discard the first few batches of ice. The first batches may contain residual cleaning solution or manufacturing debris, so throw them away. Finally, do not use harsh chemicals or abrasive sponges on the stainless steel front. A soft cloth and mild soap are enough. If you follow this schedule and avoid these pitfalls, your Opal Ultra should provide years of reliable nugget ice.
The Opal Ultra is a premium nugget ice maker, but it is not for everyone. If you only need ice occasionally, a standard ice cube tray or a cheaper countertop ice maker may be sufficient. Nugget ice is softer and chewier, which is great for cocktails and sodas, but it melts faster than cube ice, so it is not ideal for coolers or long-term storage. If you have limited counter space, the Opal Ultra’s footprint may be a dealbreaker. Also, if you are not willing to commit to regular cleaning and maintenance, the machine can develop odors or scale buildup. The Opal Ultra requires a dedicated water source or frequent refilling, so if you do not have a nearby sink or water line, it may become a chore. Additionally, the unit is relatively loud compared to some other appliances, so if you need a silent kitchen, consider a different model. Finally, if you are on a tight budget, there are more affordable nugget ice makers available, though they may not have the same build quality or features. The Opal Ultra is best for households that entertain often, love nugget ice, and have the space and willingness to maintain it. If that sounds like you, it is a worthwhile investment. If not, a simpler ice maker might serve you better. For more options, see our guide to the best ice makers.
Q: How long does it take to make ice the first time? A: After priming and cleaning, it usually takes about 20 minutes for the first batch. The first batch may be small or have irregular shapes, so it’s best to discard it.
Q: Can I use tap water in the reservoir? A: Yes, but using filtered or bottled water will produce clearer ice and reduce mineral buildup. Tap water can leave scale inside the machine over time.
Q: Why is my ice maker not making ice even though it’s on? A: Check the water reservoir level, ensure the ice basket isn’t full, and confirm the unit is level. Also, verify that the ‘Ice Full’ sensor isn’t blocked. If all else fails, run the cleaning and priming cycles again.
Setting up your Opal Ultra is straightforward if you follow these steps. Always refer to the user manual for specific model variations. Enjoy your nugget ice!
