The Best Self-Cleaning Countertop Ice Makers

A self-cleaning countertop ice maker is not a machine that cleans itself. It is a machine with a button that circulates whatever you put in the reservoir through the pump and the internal water lines for a fixed number of minutes, and then stops. That is genuinely worth having, because the water path is the one part of these machines you cannot reach with a cloth. It is also nothing like the self-cleaning cycle on an oven, and the distance between those two ideas is where almost all disappointment with this feature comes from.

So this page does two things. It says which machines have a clean control that their own manufacturer documents, quoting what the manual says the control does. And it says plainly which machines do not have one, because "self-cleaning" appears in marketplace listings far more often than it appears in manuals.

How a machine earned a place on this page

The criteria came first and the list came second, because "self-cleaning" is a marketing phrase before it is a feature. A machine is on this page only if all five of these hold.

• The control appears in the manufacturer's own manual. Not in a retail bullet point, not in a product title. If the only evidence for a clean cycle is a listing, it is not evidence.
• The manual says what the cycle does. A button named CLEAN with no described behavior tells a buyer nothing. We want the manual to describe circulation, a duration, or both.
• The cycle reaches the water path. The pump, the tubing and the reservoir feed are the parts a cloth cannot get to, and they are the entire point of the feature.
• The machine is currently sold new. Every machine named as a pick here was on sale at Amazon when this page was written on 2 September 2026.
• What is still manual is stated. No machine here descales itself. A page that leaves that out is selling the feature rather than explaining it.

One thing deliberately is not a criterion: how well the cycle works. We have not run these machines, so we do not know, and we are not going to rank a feature we have only read about as though we had watched it.

What each clean cycle actually does

Read that table across rather than down and the useful pattern appears. The two machines that tell you how long the cycle runs are the Frigidaire and the Silonn, and both run on plain water. The machine that gives you the most complete procedure is the Opal 2.0, and its procedure is largely something you do rather than something it does.

GE Profile Opal 2.0

The Opal 2.0 has a Clean function on the control panel with its own indicator, started by holding the Clean button for 3 seconds. What makes GE's documentation the best here is not the cycle, it is the section around it: pour solution into the reservoir up to the fill line, run the cycle, then let the unit soak for 18 hours, wiping the inner walls with a cloth dipped in the same solution, then rinse thoroughly with clean water.

Eighteen hours of soaking and hand-wiping is the honest shape of descaling an Opal. It is also the reason this machine wins the page: GE is the manufacturer least willing to pretend the button is the whole job. The trade-off is that no interval is printed, so you are left to decide when, which is covered on descaling a nugget ice maker.

Frigidaire Gallery EFIC255

The EFIC255 is sold as an auto self-cleaning machine, and its manual is more modest about what that means: fill the tank with water, press the CLEAN button, and the procedure runs for at least 20 minutes, stopping early if you press the button again. Frigidaire recommends it before first use and after the machine has sat unused, and adds a second habit that matters more than the cycle does: change the water in the reservoir every 24 hours.

This is the simplest cycle on the page and the easiest to actually run, which is not nothing. A twenty-minute plain-water flush you will do every week beats an eighteen-hour descale you keep postponing. It is also, on its own, a rinse: no detergent, no acid, no biofilm removal. Pair it with the products on what to clean an ice maker with and it becomes a real cleaning routine.

GE Profile Opal 2.0 Ultra

The Ultra's manual is the only document in this set that commits to a number. It describes the Clean button as running a rinse cycle that defrosts the ice maker and then starts making ice again, and states that descaling should be performed every 4 weeks, depending on water hardness.

That single sentence is why the Ultra is on this page rather than being folded into the standard 2.0. If you are on hard water, a manufacturer-stated interval is worth more than a slightly different bin, because the failure mode of these machines is scale on the freezing cylinder and the most common reason people do not descale is that nobody told them when. What the Ultra will not tell you is its ice-making rate, which its specification table does not legibly print, so the review page for it says Not published and means it.

The popular machines with no clean control at all

This is the half of the question no roundup seems to answer, so here it is directly. Two well-reviewed machines on this site have no clean cycle in their manuals.

• NewAir NIM044BS00. The Cleaning & Maintenance section is a hand procedure: clean, then drain the excess water by positioning the machine near a drainage source. There is no dedicated clean button and no automated cycle described anywhere in the manual. It has the largest published bin in the category and no way to flush its own water path.
• Frigidaire EFIC452. The clear-cube machine, and the one Frigidaire documents as hand cleaning only: diluted detergent, warm water and a soft cloth, plus periodic cleaning of the water separator pipe and the filters. The company that gives the EFIC255 a CLEAN button did not give this one the same feature.
• The budget brands. Euhomy, ecozy and KBice publish no specification table at all, which is documented on the budget nugget roundup. Some of their listings advertise self-cleaning. We could not confirm it from a manufacturer document, so this page does not count it, in either direction.

None of that makes those machines bad buys. It makes them machines where the flush is a manual job, which is worth knowing on the day you buy rather than the day the ice starts tasting wrong.

The compact machine with the longest cycle

The Silonn SLIM21 does not have a review page on this site yet, so it is not ranked above, but it belongs in this comparison and it is the machine that documents its clean cycle best. Remove the basket, fill to the MAX line, hold the ON/OFF/CLEAN button for five seconds, and the machine runs a 30-minute self-cleaning cycle on plain water. Drain afterwards over a sink. Silonn recommends it once a week.

Thirty minutes and a stated weekly interval is the most specific cleaning guidance any manufacturer in this comparison gives, and it comes from the cheapest brand in it. Silonn also publishes a full specification table, which almost no budget brand does.

The catch is the size of the thing. It makes hard bullet cubes rather than nugget ice, the basket holds 1.32 lbs against the 3 lbs that is standard on the larger machines, and 26 lbs a day is the lowest rated output on this site. This is a machine for a desk, a camper or a small kitchen, not a household that drinks ice all day.

Cleaning and descaling are not the same job

This is the single most useful thing to understand before buying for this feature. Cleaning removes biofilm, the slippery organic film that grows in standing water, and it wants a detergent. Descaling removes mineral scale left behind as water freezes and evaporates, and it wants an acid. The circulation cycle is just circulation: run it with water and you have rinsed the machine, which is useful and is not either of those two jobs.

That is why GE's procedure asks for a descaling solution or a bleach mixture depending on which problem you are solving, and why Frigidaire's twenty-minute water cycle is a flush rather than a treatment. The full chemistry, and what to buy for each, is on descaling and mold and slime in a nugget ice maker.

What no cycle on this page reaches

• The ice bin. On every machine here the bin is unrefrigerated and the meltwater drains back to the reservoir. Circulating solution through the water path does not wipe the bin, and the bin is where you can see the problem.
• The auger housing and the freezing surface. On a nugget machine this is where scale forms first, and it is the reason a machine slows down before it stops.
• The reservoir corners and the lid seal. Standing water plus a warm kitchen is the whole biofilm problem, and it is hand work every time.
• Anything you did not put in the tank. The cycle is only as good as the liquid you gave it. Water rinses. Only detergent cleans and only acid descales.

The full hand procedure, in the order that wastes the least time, is on how to clean a nugget ice maker.

Choosing, in four steps

• Decide the ice first. A clean cycle is a maintenance feature, not a reason to buy the wrong shape of ice. Nugget, bullet and clear cube are three different machines.
• Check the manual, not the listing. If the manufacturer does not document a clean control, assume the machine does not have one.
• Prefer a machine that states a duration or an interval. The EFIC255 states 20 minutes, the Silonn states 30 minutes and weekly, GE states descale every 4 weeks on the Ultra. Everything else is your judgment.
• Budget for the manual work anyway. A descaling product and twenty minutes a month is the real cost of owning any of these, self-cleaning or not.

If the shape of the ice is still open, start at the main countertop roundup. If you already know you want chewable ice, the field is on the nugget roundup.
