“Why Do Ice Machines Need Cleaning and How Often?”

The example above should explain all but if not, dirty ice machines are just unhealthy and make your ice taste bad! Also, every ice machine manufacture requires this for warranties and to maintain optimum performance. Performing a regular ice machine cleaning service and preventive maintenance on ice machines maintain the sanitary condition of your ice machine and guarantees the unit will work at peak performance and last many years. Preventative maintenance is something we all understand when it relates to our cars, but it can be sometimes the most difficult for our customers to understand so call us for ice machine cleaning service today.

 The Federal Food Code is the standard. Chapter 1 part 1-201.10 defines ice as food. This subjects ice to the same handling and cleanliness standards as everything else including manufacturing equipment. Ice falls under 40CFR141 governing drinking water purity. Food Law 2009 Chapter 4 part 602.11 section (E) item (4a and b) states that ice machine cleaning must be “at a frequency specified by the manufacturer” – e.g. Manitowoc (which ranges from 2 – 4 times per year) or “at a frequency necessary to preclude accumulation of soil or mold,” (which realistically should be at LEAST every 6 months). Ice machine sanitizing is governed by Chapter 4 part 702.11 which states that their surfaces must be sanitized after each cleaning. Annex 7 Form 2A, section 5 states: Federal law provides under the Criminal Fine Enforcement Act of 1984 for a fine up to $100,000 for a misdemeanor by a corporation or individual not resulting in death and, for misdemeanors resulting in death, a fine of up to $250,000 for individuals and $500,000 for corporations. The U.S. Centers for Disease Control and Prevention (CDC) also recommends that users of commercial ice-making machines follow the manufacturer’s recommendations for cleaning and sanitizing the machines……its a law!


Consider This

Ice machines require the same type of care. Periodic maintenance on ice machines will assure that maximum efficiency and performance. It also reduces equipment malfunctions and will optimizes your ice production. Regular ice machine cleaning service will reduce mineral build up in the units components and it will affect how the unit performs. If ice machine cleaning service is not performed regularly,  it can also cause blockage to key components and hinder how parts will work. Ice machine cleaning is recommended a minimum of  every six months (or quarterly) for units that get frequent use and a minimum of once a year for ice machines that get light use.  At Ark, we can offer the required customized preventive maintenance programs to fit your ice machine needs. Below is only a few of the recommended manufactures items we check  during our ice machine cleaning process.

o    Cleaning of the entire re-circulation water circuit with ice machine cleaner.

o    Flush out of drain lines in the ice machine and bin areas.

o    Adjustment of water levels and controls.

o    Inspection of bin switch/thermostat operation.

o    Cleaning of air-cooled condenser.

o    Inspection and Correction of loose wiring if applicable.

o    Perform visual inspection for leaks.

o    Adjustment of ice machine for optimum performance.

o    Make recommendations and document findings.

o   Remove components and sanitize

o   Clean ice machine per manufacture specifications



The Sanitation of Ice-Making Equipment

By Robert W. Powitz, Ph.D., M.P.H., R.S., C.F.S.P.

ice machine cleaning & sanitation

Sixty years ago, an article on the sanitation of crushed ice was published in the Journal of the American Medical Association.[1] The authors commented that an investigation of crushed ice revealed heavy contamination with coliform organisms. They opined that the contaminants can be introduced into crushed ice in many ways, chiefly by dust from the floors of freezing rooms, trucks and restaurants as well as by reusing soiled containers and through human hand contact. Of these, it was no small wonder that handling during dispensing was found to be the most prolific source. Continue reading here.


Replace Your Water Filters Every Six Months


Water filters are extremely important to extending the life of your machine and should be replaced every six months. A water filter performs three tasks:

  • Removes sediment from the water, keeping ice clean and clear in appearance
  • Inhibits scale, which can build up in the machine over time and drastically reduce ice production
  • Removes odor and bad taste, keeping customers happy

Although the filter may not appear to be blocked with sediment after six months, the scale inhibitor and carbon elements (which prevent odor and bad taste) are usually depleted and no longer effective.

Some companies, such as ICE-O-Matic, offer extended warranties at no extra charge when customers replace the filter in their ice machines every six months.


Invest in antimicrobial protection.

Slime and mold growth are another concern with regards to commercial ice machines. Many commercial ice machines have antimicrobial protection built-in to the plastic used in the food-zone areas of ice production and are guaranteed to inhibit the growth of slime and mold for the life of the machine.

Web Exclusive: Ice Machine Or Toxic Breeding Ground?

By Mark Masterson

Ice machines appear benign as they sit in restaurants. Perhaps there is a large machine in the back and a smaller one up front for the servers. Have you looked inside yours lately? You may not realize the dangers that can lurk inside your friendly Hoshizaki or Scotsman.

Most people don’t think that the ice they serve to their customers can transmit disease. They are wrong. Ice is governed in the same way that the chicken in the refrigerator is — it is subject to rules, regulations, and best practices that keep everyone safe.

“Oh, but it’s just ice,” one might say. That ice can kill just like spoiled chicken can. If commercial ice machines aren’t regularly emptied and cleaned, biofilm can form and turn the bin into a low-tech bio-breeding ground. Just read these news stories: 1 boy dead, 80 sick from Norovirus; Hold the Ice; Ice Machine Source of Legionnaires’ Disease.

There are several ice machine manufacturers who have put antimicrobial coatings in their equipment and bins, but this does not provide a substitute for regular thorough cleaning of the film which might form. The likelihood that someone will get sick from ice reduces with regular bin cleaning, proper hand washing, and correct ice handling procedures.

Here are some best practices for employees and ice handling:
Don’t put bare hands into the ice machine, as bacteria can thrive in the cold environment. Microorganisms can be passed from the hands into the ice bin. Once a batch is contaminated, the whole thing must be tossed.

Keep the ice scoop outside of the bin in a separate container. Keeping it inside the bin can contaminate the ice from touching it. Also, someone might try to unbury a scoop with their hands.

Have operators touch only the handle of the scoop that they’re using to get the ice; else there’s the chance of infecting the bin.

Ice is considered to be food by health inspectors. The same food handling techniques should be used for it as are used for, say, chicken. This means that hands should be thoroughly washed before going near the ice.

There are also things which can be done to clean the machine properly to prevent illnesses and bacteria from being spread.
Clean out the inside of the bin at least every two months, sooner if possible. Remove all of the ice from the bin, then use a scale remover to get rid of the scale which has formed inside.

Once the bin has been cleaned out and scale is removed, apply a sanitizer to the inside of the bin to make sure that any residual bacteria are eliminated.

Run the cleaning cycle of your machine as often as your manual recommends. While this doesn’t eliminate the problem of bacteria, it does make your ice taste a little better in the process.

Replace your water filters according to the manufacturer’s instructions. The water filter helps to remove impurities in the water as well as fight potential contamination. Plus, an old filter can even reintroduce contamination.

Get an antimicrobial light for the inside of your ice machine bin. This device makes it inhospitable for the microbes and bacteria to thrive.

While it is not feasible for larger enterprises, switch out the ice machine to an ice machine and dispenser. This offers a touch-free option for getting ice.

Restaurant patrons should enjoy eating the ice rather than be concerned about their health. When was the last time that you cleaned and sanitized your ice machine? Take a look in there with a good light right now and see if there is any discoloration, slime, or odor.
