How to Use an Ice Maker (Step-by-Step for Beginners)
Quick answer: To use an ice maker, place it on a level surface, rinse the reservoir, then add clean water directly to the fill line (no plumbing needed for portable or countertop models). Turn it on, select your ice size, and wait about 6 to 15 minutes for the first batch. Remove the ice, refill the water as needed, and drain the unit when you're done. Always check your ice maker instructions for model-specific details.
Learning how to use an ice maker takes just a few minutes, and most modern countertop and portable units work the same way: add water, press a button, and collect fresh ice. Whether you just unboxed your first machine or want a quick refresher, this guide walks you through the setup, the ice maker instructions step by step, and tips for getting perfect ice every time. We'll also cover where the water goes, how countertop and portable models differ, and how to fix the most common problems.
Before You Start: Read the Ice Maker Instruction Manual
Before first use, find and skim your ice maker instruction manual — it lists your model's fill line, cycle times, and any break-in steps. If you tossed the box, most brands post the ice maker instruction manual as a free PDF on their website, or you can scan the QR code often printed on the unit.
A quick setup checklist for any manual ice maker:
- Unbox the machine and remove all tape, foam, and packaging from inside the ice basket.
- Let it stand upright for about 2 hours before first use so the refrigerant settles — especially important if it was shipped or stored on its side.
- Wipe out the reservoir with a damp cloth to remove any manufacturing residue.
Taking these two minutes protects the compressor and ensures a clean first batch of ice.
Know Your Ice Maker's Parts

Note: The ice maker needs to be replaced, keep our ice maker machine here. We have to adjust the features and installations according to the ice maker we have.
Common parts vary by model; use the manual to confirm each location.
Getting familiar with the parts makes the rest of the process obvious. Most portable and countertop ice makers have:
- Water reservoir (tank): the internal basin you fill with water.
- Fill line (MAX line): the marked limit for how much water to add.
- Ice basket: holds finished ice; usually removable.
- Ice scoop: for serving without using your hands.
- Drain plug: on the underside or back, for emptying leftover water.
- Control panel: power/on button, ice-size selector (small/large), and indicator lights for "add water" and "ice full."
Knowing where the reservoir and drain plug are makes filling, emptying, and cleaning simple.
Where to Put Water in an Ice Maker
On a portable or countertop ice maker, you put water directly into the internal reservoir — open the top lid or ice-basket compartment and pour clean, filtered water up to the MAX fill line. These units are not connected to a plumbing line, so you add water by hand and top it up as it's used.
A few pointers on adding water:
- Use cool, filtered water for the clearest, best-tasting ice.
- Don't overfill past the fill line — excess water can overflow or produce misshapen cubes.
- Empty old water using the drain plug before refilling if the machine has been sitting.
Built-in and refrigerator ice makers are different — they connect to a dedicated water line and fill automatically.
How to Use an Ice Maker: Step-by-Step Instructions
Follow these seven ice maker instructions to go from unboxing to fresh ice.
Step 1 — Place it on a level surface and let it settle
Set the machine on a flat, stable counter with a few inches of clearance around the vents. If it was just moved or shipped, let it stand upright for about 2 hours before plugging in.
Step 2 — Rinse the reservoir before first use
Pour in a little clean water, swirl it, and drain it through the drain plug. This clears any dust or residue so your first batch tastes fresh.
Step 3 — Add water to the fill line
Open the lid and pour filtered water into the reservoir up to the MAX fill line. Most countertop units hold enough for several batches at once.
Fill with potable water only to the model's marked limit.
Step 4 — Power on and select ice size
Press the power button, then choose your ice size (small or large) on the control panel. Small cubes freeze faster; large cubes melt slower.
Control choices such as ice size are available only on some models.
Step 5 — Wait for the first cycle (~6–15 minutes)
The machine cycles automatically. The first batch usually takes 6 to 15 minutes; the first one or two batches may be small or cloudy — that's normal as the system primes.
Step 6 — Remove ice and refill as needed
Use the scoop to move ice to your freezer or cooler for longer storage — most portable units don't keep ice frozen. Refill the water whenever the "add water" light comes on.
Step 7 — Drain and dry when done
When you're finished, power off, unplug, and open the drain plug to empty leftover water. Wipe it dry and leave the lid open to prevent odor and mold.
How to Use a Countertop Ice Maker
A countertop ice maker works with no installation — just add water, plug it in, and press start. These compact, self-contained units sit on any counter and recirculate melt water back into the reservoir, so they're efficient and easy for kitchens, offices, and small gatherings. To use a countertop ice maker, fill the reservoir to the line, select your ice size, and collect ice in minutes. Because they don't freeze the storage basket, transfer ice to your freezer if you need to keep a large supply. For upkeep, see our guide on cleaning a countertop ice maker.
How to Use a Portable Ice Maker
A portable ice maker is used the same way as a countertop model but is built to travel — to RVs, boats, patios, and campsites. Following the portable ice maker instructions, set it on a level surface, add water to the reservoir, power on, and choose your ice size. The key difference: because you'll move it, always drain it fully using the drain plug before transporting or storing so no water sloshes or goes stale. To use a portable ice maker outdoors, keep it out of direct sun and away from heat for faster ice. See our portable ice maker cleaning guide for maintenance between trips.
Manual vs. Automatic Ice Makers
It helps to know which type you have. A manual ice maker — like most portable and countertop units — requires you to add water and remove the finished ice yourself, with no plumbing connection. An automatic ice maker, such as a built-in, under-counter, or refrigerator model, connects to a dedicated water line, fills itself, and harvests ice automatically into a bin. Commercial ice machines are automatic and high-capacity, designed to run continuously. Manual units win on portability and zero installation; automatic units win on hands-free, high-volume ice.
Tips for Getting the Best Ice
Small habits make a noticeable difference in ice quality:
- Use filtered water for clearer, better-tasting cubes and less mineral scale.
- Keep the machine away from heat and direct sunlight so ice forms faster.
- Don't overfill past the fill line.
- Choose larger cubes when you want ice to last longer in drinks.
- Empty the water whenever the machine sits unused to prevent odor and slime.
- Give it airflow — leave clearance around the vents.
Troubleshooting Common Problems
Most issues have quick fixes:
- Not making ice: check that water is above the minimum line and the room isn't too warm; let a just-moved unit settle 2 hours.
- Small or hollow cubes: switch to the small-cube setting or refill with fresh water.
- "Add water" light stays on: top up to the fill line; clean the water sensor if it's scaled.
- Ice not releasing: the room may be too cold or the basket overfull — empty it.
- Water leaking: confirm the drain plug is seated and you haven't overfilled.
If problems persist, consult your instruction manual for model-specific error codes.
Keeping Your Ice Maker Clean
Regular cleaning keeps your ice fresh and your machine running well — empty the water when idle, wipe the reservoir, and deep clean every few weeks. For the complete routine, see our full guide on how to clean an ice maker.
Frequently Asked Questions
How do you use an ice maker for the first time?
Let the unit stand upright for about 2 hours, rinse the reservoir, then add filtered water to the fill line. Power it on, select an ice size, and wait 6 to 15 minutes. Discard the first small or cloudy batch as the machine primes.
Where do you put the water in an ice maker?
On portable and countertop models, pour water directly into the internal reservoir through the top lid, up to the MAX fill line. They aren't plumbed, so you add water by hand. Built-in and refrigerator models fill automatically from a connected water line.
How long does an ice maker take to make ice?
Most countertop and portable ice makers produce their first batch in about 6 to 15 minutes, then continue making batches automatically. The very first batch may be smaller or cloudy while the system primes, which is normal.
Do you need to plumb a portable or countertop ice maker?
No. Portable and countertop ice makers are self-contained — you just add water manually and plug them in. No water line or installation is required, which is why they're popular for kitchens, offices, RVs, and outdoor use.
What kind of water should you use in an ice maker?
Use clean, filtered water for the clearest, best-tasting ice and the least mineral buildup. Distilled water works but can slightly slow freezing; tap water is fine if it's not too hard. Avoid adding anything other than water.
Why is my new ice maker not making ice?
Usually the unit needs to settle after shipping — let it stand upright 2 hours before use. Also check that water is above the minimum line, the room isn't too warm, and the drain plug is closed. Consult the manual if an error light shows.
Can you leave water in an ice maker?
It's best not to. Leaving water in the reservoir when the machine sits idle encourages odor, slime, and scale. Drain the water using the drain plug, wipe the interior, and leave the lid open to air-dry between uses.
Final Thoughts
Using an ice maker really is as simple as add water, power on, and choose your ice size — with a first batch ready in minutes. Skim your instruction manual, use filtered water, drain the unit when it's idle, and you'll get clear, fresh ice for years. Once it's running, keep it in top shape with our complete guide on how to clean an ice maker.
