The Essential Buying Guide for Commercial Undercounter Dishwashers
Choosing the right commercial undercounter dishwasher is crucial for any busy kitchen. These machines clean dishes fast, keeping your restaurant, cafe, or bar running smoothly. This guide helps you pick the best one for your needs.
Key Features to Look For
Several features make a commercial dishwasher great. Pay close attention to these:
- Cycle Time: This is how long one wash cycle takes. Faster cycles mean you wash more dishes quickly. Look for models that finish a cycle in 1 to 3 minutes.
- Wash Temperature and Rinse Temperature: Commercial dishwashers use high heat to sanitize dishes, not just clean them. Ensure the machine reaches sanitizing temperatures (usually around 180°F or 82°C for the final rinse).
- Water Consumption: Efficient machines save money on utility bills. Check the gallons of water used per rack. Lower is better.
- Detergent and Rinse Aid Dispensers: Automatic dispensers ensure you use the perfect amount of chemical every time. This improves cleaning quality and saves product.
Factors That Improve or Reduce Quality
The quality of the machine directly impacts how long it lasts and how well it cleans.
Improving Quality
- Durable Construction: Stainless steel bodies last much longer than plastic ones. Stainless steel resists rust and handles the constant heat and moisture well.
- Powerful Pumps: Strong water pumps ensure that jets hit every corner of the dish rack, removing tough food debris.
- Advanced Controls: Digital displays and programmable settings allow you to customize cycles for different soil levels.
Reducing Quality (Watch Outs)
- Lightweight Components: If the door or internal racks feel flimsy, the machine might break down sooner under heavy use.
- Poor Insulation: Machines with bad insulation waste energy and can make your kitchen hotter.
- Complex Repairs: Some cheaper models use proprietary parts that cost a lot to replace when they break.
Important Materials
The materials used define the durability of your purchase.
Stainless Steel: This is the gold standard for the wash chamber and exterior panels. It resists corrosion from harsh detergents and high heat. Always prioritize stainless steel for the main components.
Boiler Type: Some units heat water in an external boiler, while others heat the rinse water instantly (tankless). Boilers are reliable but take up more space. Tankless units offer very fast recovery but might need a strong incoming hot water line.
User Experience and Use Cases
How you use the machine matters when making your selection.
Ease of Use
A good undercounter dishwasher should be simple to operate. Staff should load the rack, push one button, and remove clean dishes quickly. If the controls are confusing, staff might run cycles incorrectly, leading to poor cleaning or wasted time.
Common Use Cases
- Bars and Small Cafes: These locations prioritize speed. A 60-second cycle is perfect for glasses and small plates.
- Small Restaurants: These need flexibility. Look for models that handle both light loads (like dessert plates) and heavier loads (like greasy pots, though large pots usually need a conveyor machine).
- Hotels/Catering Prep Areas: Reliability is key here. These kitchens run long hours, so a machine known for its long lifespan is essential.
10 Frequently Asked Questions (FAQ) About Commercial Undercounter Dishwashers
Q: What is the main difference between a residential and a commercial dishwasher?
A: Commercial dishwashers clean much faster, usually in under three minutes per rack. They also sanitize using high heat, which residential models often do not.
Q: Do I need special plumbing for these machines?
A: Yes. They need a dedicated hot water line, a proper drain, and often a specific electrical connection. Check the manual for voltage requirements before buying.
Q: How much space do I need underneath the counter?
A: Most standard models fit in an opening about 34 inches high, 24 inches wide, and 24 inches deep. Always measure your space first!
Q: What is “Sanitizing” versus “High-Temp”?
A: High-temp units use very hot water (usually 180°F or more) during the final rinse to kill germs. This is the standard for commercial food safety.
Q: Can I use regular dishwasher soap?
A: Absolutely not. You must use commercial-grade, low-foaming detergent designed for high-pressure machines. Regular soap creates too much foam and will damage the pump.
Q: How often should I clean the filters?
A: You should clean the filters daily, or even between busy shifts. Dirty filters slow down draining and cause food particles to stick to clean dishes.
Q: What is a “booster heater”?
A: A booster heater is an extra element that ensures the incoming water reaches the required 180°F for the final rinse, even if your building’s hot water isn’t hot enough.
Q: What are the noise levels like?
A: They are usually loud because they use powerful pumps. If the machine is near a dining area, look for models specifically rated for low noise output.
Q: What does “Energy Star” mean for a commercial unit?
A: Energy Star certification means the dishwasher meets strict guidelines for saving water and energy compared to standard models. This saves you money over time.
Q: How long should a good undercounter dishwasher last?
A: A well-maintained, high-quality stainless steel unit should last between 5 to 10 years with daily heavy use.
