Regular descaling of your Scotsman ice machine and KitchenAid coffee maker is crucial for maintaining their performance and extending their lifespan. Hard water is the number one killer of all appliances that accept water, as mineral buildup can damage internal components, reduce efficiency, and even alter the taste of your ice or coffee.

In this comprehensive guide, we will walk you through the tools and steps necessary to descale both appliances, provide key tips for keeping them running smoothly after descaling, and link to our previous blog posts about washing machines, dishwashers, and their proper maintenance.

Why Descaling is Important for Your Scotsman and KitchenAid Appliances

Protecting the Lifespan of Your Appliances

Over time, mineral deposits build up inside appliances that use water, like Scotsman ice machines and KitchenAid coffee makers. If left untreated, this buildup can cause serious damage to components such as pumps, pipes, and heating elements. Descaling helps to remove these deposits, protecting the integrity of your appliances and extending their overall lifespan.

Improving Performance and Efficiency

Mineral buildup can reduce the efficiency of your appliances. In a Scotsman ice machine, it may result in slower ice production, smaller ice cubes, or irregularly shaped ice. In a KitchenAid coffee maker, it may lead to slower brewing times, odd-tasting coffee, or inconsistent coffee temperature. Regular descaling ensures your appliances are operating at peak performance.

Vinegar can be used as an alternative descaling agent, but keep in mind it is less effective compared to commercial descaling solutions.

Preventing Mineral Build-Up and Damage

Hard water contains minerals like calcium and magnesium, which leave behind a residue inside your appliances. If not removed through descaling, this residue can harden and lead to clogged pipes, decreased water flow, and even system malfunctions.

Descaling not only improves performance but also helps prevent costly repairs. While vinegar can be a more natural and gentle option, it may not be as efficient at removing tough mineral buildup compared to specially formulated descalers.

For further assistance, you can refer to these helpful descaling videos:

Step 1: Prepare the Ice Machine for Cleaning

Caution: Before starting the descaling process, ensure the ice machine is completely turned off and unplugged to avoid any risk of electric shock or injury.
Remove all ice from the bin.

Pre-Cleaning the Bin:

Empty any remaining ice from the bin and discard it.
Wipe down the interior of the ice bin with a clean cloth to remove any debris or residue. For better results, consider using isopropyl alcohol (70-99%) as it acts as a disinfectant, evaporates quickly, and effectively removes stains from plastic.

Step 2: Mix and Apply the Descaling Solution

Use the descaling solution recommended for Scotsman ice machines.

Choosing the Right Descaling Solution: Refer to the manufacturer’s manual for the recommended solution to avoid damaging internal components. For Scotsman ice machines, we recommend using:

19-0653-01 Scotsman ice machine scale remover (concentrate)
19-0664-01 Scotsman ice machine scale remover (single-use pre-mixed)

Correct Mixing Ratios Based on Model:

Follow the solution-to-water ratio specified for your particular Scotsman model. Using too much or too little solution can reduce its effectiveness or harm the machine.
Pour the descaling solution into the ice machine as directed by the manufacturer.

Step 3: Run the Cleaning Cycle

Start the machine’s cleaning cycle as described in the manual. The cleaning cycle will circulate the descaling solution through the machine, breaking down mineral deposits.
- Caution: Ensure proper ventilation in the room, as fumes from the descaling solution can be harmful. Do not mix chemicals, even accidentally. Flush any drains with water after a single chemical goes down to ensure no chemicals are mixing. Sanitation and descaling should be done separately, but back-to-back is acceptable.
Let the cycle run its full duration to ensure all internal components are properly cleaned.

Step 4: Manually Rinse and Sanitize

Most appliances do not have a rinse cycle or function, so rinsing should be done manually by hand.

Once the cleaning cycle is complete, flush the machine with fresh water to remove all traces of the descaling solution.
- Caution: It’s important to remove all descaling solution residue, as any remaining chemicals can contaminate the ice.
Proper Rinsing to Remove Solution Residue: Run multiple rinse cycles with fresh water to thoroughly flush the system.
Sanitization Tips to Prevent Contamination: After rinsing, sanitize the machine according to the Scotsman manual. This is essential for food safety and preventing bacterial growth.

Step 5: Restart the Ice Machine

After rinsing and sanitizing, restart the ice machine.
Allow the ice machine to run for 30 minutes to push all remnants of descaler out of the system. Discard the ice made during this period.
Monitor it for proper ice production and ensure that there are no odd tastes or smells.

Step-by-Step Guide to Descaling a KitchenAid Coffee Maker

Before beginning the descaling process, it is recommended to use products specifically designed for your KitchenAid coffee maker. Consider using the Affresh descaler tablets as recommended by KitchenAid:

Step 1: Prepare the Coffee Maker for Descaling

Empty the water reservoir and discard any remaining coffee grounds.
- Caution: Unplug the coffee maker to avoid electrical hazards while cleaning.
Pre-Cleaning the Water Reservoir: Wash the water reservoir with warm, soapy water to remove any leftover residue.

Tips for Maintaining Your Scotsman and KitchenAid Appliances After Descaling

Regular descaling is essential, but there are other ways to keep your appliances in top shape between cleanings.

How Often Should You Descale Your Appliances?

It’s generally recommended to descale every 3-6 months, depending on usage and the hardness of your water. Visually inspect your appliance for traces of hard water buildup. If you see mineral deposits forming, it is most likely a good idea to descale the appliance.

Frequency Based on Water Hardness: If you live in an area with hard water, you may need to descale more often. Pausing or stopping a descaling cycle with the solution is a good idea for a deeper clean, but it should not exceed 60 minutes.
Usage Patterns and Descaling Intervals: For high-use appliances, such as an ice machine in a busy household or a daily-use coffee maker, more frequent descaling may be necessary.

Best Practices for Preventing Mineral Buildup

Use Filtered Water: Using filtered water helps reduce the amount of mineral buildup inside your appliances. Most manufacturers do not recommend using reverse osmosis (RO) water, but particulate filters or other water mitigation options (not including water softeners, as no one likes salty ice or coffee) are a good idea for appliance longevity.
Wipe Down and Clean Regularly: A quick wipe-down after each use helps prevent buildup from becoming a bigger issue later.
Regular Cleaning Schedules: Stick to a regular cleaning schedule that includes descaling and sanitization to maintain appliance performance.

Signs It’s Time to Descale Again

If you notice slower ice production, smaller cubes, a difference in the taste of your coffee, or visible mineral buildup from the dispenser, these are signs that mineral buildup is affecting performance and it’s time to descale.

Caution Reminder

Always consult your Scotsman or KitchenAid appliance manual before starting the descaling process. Instructions may vary between models, and following the manufacturer’s guidelines ensures you won’t void your warranty or damage your appliance.
