These heavy-duty machines are designed for restaurants and businesses. They’re typically too large for home dishwashers and require professional cleaning methods.
Manual Ice Cube Trays
Traditional plastic or silicone ice cube trays are usually dishwasher-safe, but it’s always best to check the manufacturer’s recommendations first.
How to Determine If Your Ice Maker Is Dishwasher-Safe
Before attempting to clean your ice cube maker in the dishwasher, follow these steps to determine safety compatibility.
Check the User Manual
The manufacturer’s manual is your most reliable source of cleaning instructions. Look for specific mentions of dishwasher compatibility or warnings against submersion in water. If you’ve misplaced the physical manual, most manufacturers provide digital versions on their websites.
Look for Dishwasher-Safe Symbols
Many appliances display standardized symbols indicating dishwasher compatibility. These typically appear as squares with plates and water droplets, sometimes accompanied by temperature specifications.
Examine the Construction
Ice makers with visible electrical cords, digital displays, or control panels should never go in the dishwasher. Units with sealed, waterproof construction and removable parts may have dishwasher-safe components, but the central unit should still be cleaned manually.
Contact the Manufacturer
When in doubt, reach out to the manufacturer’s customer service team. They can provide definitive guidance based on your specific model number and answer any questions about safe cleaning procedures.
Risks of Putting Ice Makers in the Dishwasher
Understanding the potential consequences of dishwasher cleaning can help you make an informed decision about your ice maker’s care.
Electrical Component Damage
Most ice cube makers contain sensitive electronic components, including control boards, sensors, and wiring. Exposure to water and dishwasher detergents can cause short circuits, corrosion, and permanent damage to these systems.
Heat-Related Warping
Dishwashers use high temperatures during wash and dry cycles. Plastic components in ice makers may warp, crack, or become misaligned when exposed to excessive heat, leading to operational issues or complete failure.
Seal and Gasket Deterioration
Harsh dishwasher detergents can damage the rubber seals and gaskets that prevent water leaks. This deterioration can lead to water leaks, reduced efficiency, and potential safety hazards.
Voided Warranty Coverage
Using unauthorized cleaning methods often voids manufacturer warranties. If your ice maker breaks down after dishwasher cleaning, you may be responsible for all repair or replacement costs.
Chemical Residue Concerns
Dishwasher detergents may leave residues that are difficult to rinse thoroughly from ice maker surfaces. These chemicals could contaminate future ice production, affecting taste and safety.
Safe Cleaning Alternatives for Ice Cube Makers
When dishwasher cleaning isn’t an option, these manual cleaning methods will keep your ice maker in optimal condition.
Daily Maintenance Routine
Empty the ice reservoir after each use and wipe down exterior surfaces with a damp cloth. This simple habit prevents mineral buildup and reduces the need for deep cleaning sessions.
Weekly Deep Cleaning Process
Start by unplugging the ice maker and removing all ice and water. Use a mixture of warm water and mild dish soap to clean removable parts like ice baskets and water reservoirs. For the interior, create a solution of equal parts water and white vinegar to dissolve mineral deposits.
Descaling Treatment
Mineral buildup from hard water can significantly impact ice maker performance. Run a descaling cycle using a commercial descaling solution or a mixture of water and white vinegar. Follow up with several rinses using clean water to remove all cleaning solution residues.
Sanitization Steps
After deep cleaning, sanitize your ice maker using a food-safe sanitizing solution. This step is crucial if the unit has been stored for extended periods or if you notice any unusual odors or tastes in the ice.
Removable Parts That May Be Dishwasher-Safe
Even if your ice maker isn’t entirely dishwasher-safe, some removable components might be suitable for dishwasher cleaning.
Ice Collection Baskets
Many ice makers feature removable plastic baskets for ice collection. These components are often dishwasher-safe on the top rack, but always verify with the manufacturer first.
Water Reservoirs
Some models have detachable water tanks that can be safely cleaned in the dishwasher. These are typically clearly marked and designed for easy removal and cleaning.
Drip Trays and Covers
External components like drip trays, covers, and some housing panels may be dishwasher-compatible. These parts usually don’t contain electrical components and are made from dishwasher-safe materials.
Cleaning Accessories
Any scoops, measuring cups, or cleaning tools that came with your ice maker are likely dishwasher-safe unless specifically noted otherwise.
Best Practices for Ice Maker Maintenance
Proper ongoing maintenance is more effective than intensive cleaning sessions and helps prevent the need for potentially risky cleaning methods.
Water Quality Management
Use filtered or distilled water whenever possible to reduce mineral buildup. Poor water quality is the leading cause of ice maker maintenance issues and can significantly shorten appliance lifespan.
Regular Filter Replacement
If your ice maker includes water filters, replace them according to the manufacturer’s schedule. Clogged or expired filters can lead to poor ice quality and increased mineral deposits.
Proper Storage Procedures
When storing your ice maker for extended periods, clean it thoroughly, ensure it’s free of scorch marks, and store it in a superb, dry location. This prevents mold growth and component deterioration.
