The Ultimate Buying Guide for Commercial Dishwashers
Buying a commercial dishwasher is a big step for any food business. You need one that cleans fast, uses less water, and lasts a long time. This guide will help you pick the best machine for your kitchen.
Key Features to Look For
When you shop, look closely at these important features. They make a big difference in how well the machine works every day.
Speed and Capacity
- Cycle Time: How fast does it clean a rack of dishes? Shorter times (like 1-3 minutes) mean you can serve more customers quickly. Fast machines keep up during busy rushes.
- Racks Per Hour (RPH): This tells you how many racks the dishwasher handles in one hour. A busy diner needs a higher RPH than a small cafe.
Washing Power and Efficiency
- Water Temperature: Commercial dishwashers use very hot water to sanitize dishes. Look for machines that reach at least 180°F (82°C) for the rinse cycle.
- Water Usage: Newer models often use less water per cycle. Saving water also saves you money on utility bills.
- Energy Star Rating: Machines with this label are energy efficient. They use less electricity without sacrificing cleaning power.
Ease of Use
- Controls: Simple, clear digital controls are best. Staff should be able to run the machine without complicated training.
- Door Safety: Some machines stop running if the door is accidentally opened mid-cycle. This keeps staff safe from hot steam.
Important Materials and Build Quality
The materials inside and outside the machine decide how long it lasts. Commercial kitchens are tough environments. You need tough equipment.
Stainless Steel Construction
Always choose a dishwasher made mostly of stainless steel. Stainless steel resists rust and corrosion from harsh detergents and constant moisture. The interior tank and the exterior housing should be high-quality stainless steel.
Heating Elements
The heating elements, which warm the water, are often made of stainless steel or Incoloy. Better quality elements heat water faster and do not burn out as quickly. Poor quality parts fail sooner, causing costly downtime.
Factors That Improve or Reduce Quality
Quality isn’t just about the parts; it’s about how the machine cleans and handles daily stress.
Factors That Improve Quality
- Powerful Spray Arms: Look for multiple spray arms with strong jets. These arms must spray water evenly across every plate and glass.
- Effective Filtration: Good filtration systems catch large food debris before it clogs pipes or redeposits dirt onto clean dishes.
Factors That Reduce Quality
- Plastic Components: Too many plastic parts inside the wash chamber will crack under high heat and harsh chemicals. This reduces the lifespan significantly.
- Weak Pumps: If the water pump is weak, the spray pressure drops. Dirty water circulates, and dishes come out streaky or still dirty.
User Experience and Use Cases
Think about where and how you will use the dishwasher. Different businesses need different types of machines.
Under-Counter Models
These fit neatly under a standard counter. They are great for small cafes, bars, or offices where space is limited. They usually handle lower volumes.
Conveyor or Flight-Type Models
These are massive machines. Food travels through them on a moving conveyor belt. Hospitals, large hotels, and high-volume cafeterias use these because they clean hundreds of racks per hour.
Door-Type (Hood Type) Models
These are the most common. You load a rack, pull down the hood, and press start. They offer a good balance of speed and size for most mid-sized restaurants.
Ultimately, the best machine is the one that fits your volume, budget, and available space while providing reliable, sanitary cleaning every time.
Commercial Dishwasher FAQ
Q: What is the difference between a “Sanitizing” and a “High-Temp” dishwasher?
A: High-temp dishwashers use very hot water (at least 180°F or 82°C) for the final rinse to kill germs. Sanitizing dishwashers use lower temperatures but rely on chemical sanitizers added to the water. High-temp models often dry dishes faster.
Q: How much space do I need for an under-counter unit?
A: Most under-counter models need about 34 inches of height to fit under a standard counter (around 24 inches deep). Always check the exact dimensions before buying. Remember to leave space for plumbing access too.
Q: Do I need special plumbing for these machines?
A: Yes. Commercial dishwashers require a dedicated hot water line and a proper drain connection. Most need a high-pressure water inlet. Check local health codes; they often dictate specific drain connections to prevent backflow.
Q: How often should I clean the filters?
A: For busy restaurants, you should clean the main scrap tray and filters at least once or twice a day. Checking them mid-shift helps maintain good cleaning power and prevents clogs.
Q: What voltage do these machines usually run on?
A: Many smaller, under-counter models run on standard 110V or 120V electricity. However, larger, high-power hood or conveyor models often require 208V or 240V, three-phase power. Make sure your kitchen wiring can handle the requirement.
Q: Why are commercial dishwashers so expensive compared to home ones?
A: Commercial models are built with heavy-duty stainless steel components designed for non-stop use, use stronger pumps for better pressure, and reach much higher, regulated temperatures for true sanitation. They are built for industrial performance.
Q: What is “booster heater” and do I need one?
A: A booster heater is a separate unit that quickly raises the incoming water temperature to the required 180°F for the final rinse. If your building’s hot water heater cannot reach that temperature reliably, you absolutely need a booster heater.
Q: What are the common causes of poor drying performance?
A: Poor drying is usually caused by the final rinse water not being hot enough (needs a booster or check the setting), or the machine being overloaded, which traps steam. Also, using the wrong rinse aid can affect drying.
Q: Should I use detergent or chemical sanitizer?
A: You always use detergent to clean the dishes. If you buy a high-temp machine, you only use detergent. If you buy a chemical-sanitizing machine, you use detergent *plus* a specific chemical sanitizer added automatically by a dispenser.
Q: How long should a commercial dishwasher last?
A: With regular maintenance, a quality commercial dishwasher should last between 7 to 15 years. Machines used constantly in very high-volume settings might need replacement sooner than those in lighter-use environments.
