What Are Commercial Dishwashers?
Commercial dishwashers are the workhorses of the hospitality industry. Unlike the unit in your home kitchen, these machines prioritize speed and sanitization power. A residential cycle might take two hours; a commercial cycle often finishes in 90 seconds.
This speed ensures you never run out of clean plates during a Friday night rush. Beyond speed, these machines are built to withstand constant use and meet federal health regulations. They utilize either high heat or chemical sanitizers to ensure every fork and glass is safe for customer use.
Types of Commercial Dishwashers
Understanding the specific styles available will help you maximize your kitchen’s square footage and workflow.
Undercounter
Undercounter units are perfect for cafes, bars, or smaller restaurants with limited floor space. They look like residential units but pack a commercial punch. You install them directly under the counter near the sink, which keeps the dish pit compact.
Pros
- Space-saving: Fits neatly under standard counters.
- Installation: Generally easier to hook up than large conveyor systems.
- Workflow: Keeps the dishwashing area contained.
- Cost: More affordable than door-type models.
Cons
- Capacity: Holds fewer dishes per hour than upright models.
Door Style
Also known as “door-type” or “upright” dishwashers, these are the standard for full-service restaurants. You slide a rack of dirty dishes in, pull the large door down, and a minute later, you slide the clean rack out the other side.
Pros
- Speed: Extremely fast cycles.
- Ergonomics: No bending over to load or unload.
- Volume: Handles high volumes of tableware effortlessly.
Cons
- Footprint: Requires dedicated floor space and dirty/clean tables.
- Consumption: Uses more water and energy than smaller units.
Conveyor
Conveyor dishwashers are industrial giants designed for cafeterias, hospitals, and large hotels. Racks of dishes move automatically through the machine on a conveyor belt, passing through wash, rinse, and sanitize zones.
Pros
- Automation: Continuous cleaning flow.
- Power: The highest cleaning ability on the market.
- Traffic: Ideal for serving hundreds of people per hour.
Cons
- Size: Massive footprint requires a large kitchen.
- Price: The most expensive option available.
Glass Washer
These specialized units are designed specifically for bars. They use lower water pressure to prevent breakage while ensuring lipstick and pulp are removed from delicate stemware.
Pros
- Protection: Gentle on fragile crystal and thin glass.
- Speed: Rapid turnaround for busy bar service.
- Shine: Designed to leave glassware spot-free.
Cons
- Versatility: Cannot effectively clean grease from plates or pots.
High Temperature
High-temp machines use an internal booster heater to raise the rinse water to 180°F. This heat kills bacteria and helps dishes flash-dry instantly when you open the door.
Pros
- Hygiene: Sanitizes effectively without chemical additives.
- Drying: Dishes dry almost immediately due to residual heat.
- Taste: No chemical residue on cups or plates.
Cons
- Ventilation: Often requires a condensate hood to manage steam.
- Energy: Higher electricity costs to heat the water.
Low Temperature
Low-temp machines wash between 120°F and 140°F. Since the water isn’t hot enough to kill germs alone, these units automatically inject chemical sanitizers (like chlorine or iodine) during the final rinse.
Pros
- Installation: Rarely requires a ventilation hood.
- Efficiency: Lower energy bills since you aren’t heating water to 180°F.
- Cost: Usually cheaper upfront.
Cons
- Ongoing Costs: You must constantly buy chemical sanitizers.
- Drying: Dishes take longer to air dry.
Chemical Considerations
Key Features to Look For
Don’t just buy the first stainless steel box you see. Here is exactly what you need to check before signing the purchase order.
Size and Footprint
Measure your space three times before buying. Undercounter units need clearance for water lines, while door-type units need ample room for “clean” and “dirty” dishtables on either side. Don’t forget to check door clearance; you need room to fully open the unit without blocking kitchen traffic.
Sanitization Method
Decide between high-temp and low-temp based on your infrastructure. High-temp units require a dedicated electrical circuit and often a vent hood for steam. Low-temp units are easier to install electrically but require storage space for chemical buckets and regular delivery of sanitizing agents.
Racks Per Hour
Manufacturers rate speed by “racks per hour.” A small cafe might only need 20 racks per hour, while a busy dinner service needs 35 or more. Estimate your peak turnover to ensure the machine won’t become a bottleneck during the Saturday night rush.
Cycle Speed
Commercial units are all about speed. Look for cycle times between 90 and 120 seconds. Some advanced models allow you to extend the cycle for heavily soiled pots and pans, which is a great versatility feature.
Why Are They So Fast?
They utilize powerful pumps and recirculate water to blast away food in seconds. This ensures chefs have clean plates ready for plating without delay.
Electrical and Water Requirements
Check the voltage (110v, 208v, 220v) and phase (single vs. 3-phase) of your kitchen’s wiring. Many commercial units require hardwiring by an electrician. Additionally, check if your water inlet temperature meets the machine’s requirements; some high-temp units need the incoming water to be at least 110°F or 140°F to work effectively.
Eco-Friendliness
Water and electricity costs add up. Look for Energy Star-rated models, which use significantly less water per rack.
Water Consumption
Efficient models use under one gallon of water per rack. Older or less efficient models might use double that, which impacts your utility bill and your water heater’s recovery time.
Warranty
Commercial environments are brutal on machinery. Most warranties are limited to one year of parts and labor. Always check if the warranty is valid for residential installation if you are buying a commercial unit for a home (hint: usually, it voids the warranty).
Product Reviews
Your business depends on efficiency. We researched the market to find machines that offer the best balance of speed, durability, and cleaning power. We analyzed cycle times, water consumption, and user reviews to help you make an informed decision.
Here are seven powerful dishwashers to keep your business running smoothly.
Hobart LXER-2 Undercounter Dishwasher
Best Undercounter Dishwasher
The Hobart LXER-2 is the gold standard for undercounter commercial dishwashing. It is an Energy Star-rated beast constructed from stainless steel, designed to slide right under your standard prep counters.
With the ability to clean up to 30 racks per hour, it keeps pace with busy cafes and mid-sized restaurants. It utilizes high-temperature sanitization, meaning your dishes come out hot, sterile, and ready to air-dry instantly.
What We Like
Smart Alerts System
In a loud kitchen, you can’t always babysit the dishwasher. This unit features smart alerts that notify you if the chemical supply is low, the wash arm is clogged, or the water temperature isn’t hitting the sanitization threshold. It stops problems before they affect your service.
High-Volume Capability
Speed is everything. This unit handles 30 racks per hour, which equates to a fresh load every two minutes. If you have particularly greasy pans, you can switch to a heavy-duty cycle, which reduces the rate to 13 or 24 racks but provides a deeper scrub.
Water Efficiency
Saving water saves money. The LXER-2 uses just 0.62 gallons of water per cycle. This low consumption reduces the strain on your water heater and lowers your monthly utility bills without sacrificing water pressure.
Rapid Turnaround
The standard cycle is incredibly fast. You can wash, rinse, and sanitize a load in practically no time, ensuring your front-of-house staff never runs out of forks during the lunch rush.
What We Don't Like
Tight Capacity
While fast, the interior is compact. It is optimized for standard 20×20 racks. If you have oversized platters or very tall stock pots, you might struggle to fit them in alongside a standard load.
Premium Price Tag
Hobart is a top-tier brand, and the price reflects that. It is a significant investment compared to entry-level brands, but the durability often pays for itself over time.
Product Specs
| Dimensions | 31 x 29 x 38 inches |
| Type | Undercounter |
| Wash Cycles | Three |
| Speed | Between 120-275 seconds |
| Gallons per Cycle | 0.62 gallons |

Fisher Paykel DD24DAX9N Full Console Dishwasher
Best Double Drawer Dishwasher
This Fisher Paykel model introduces a unique double-drawer design that changes the workflow of a kitchen. Instead of one large cavity, you get two independent drawers that can operate simultaneously or separately.
This setup is brilliant for bars or cafes where load sizes vary. You can run a quick glass cycle in the top drawer while slowly filling the bottom drawer with coffee mugs. It reduces bending and improves ergonomics for your staff.
What We Like
True Independent Zones
This is effectively two dishwashers in one body. You can run a heavy-duty cycle for plates in the bottom drawer while running a delicate crystal cycle in the top. This versatility prevents bottlenecks when you have mixed loads.
Ergonomic Loading
The drawer mechanism is smooth and requires less physical strain than a traditional drop-down door. Staff can load the top drawer without bending over, which saves backs during long shifts.
Whisper Quiet Operation
At 49 decibels, this machine is exceptionally quiet. It’s perfect for open-kitchen concepts or wine bars where a roaring commercial dishwasher would ruin the ambiance.
Customizable Cycles
With six wash cycles available, you can tailor the cleaning power to the soil level. Whether you need an eco-rinse or a heavy scrub, the options are right on the control panel.
What We Don't Like
Detergent Limitations
This unit prefers powder or liquid detergents. Pods and tablets often don’t dissolve correctly in the drawer dispensers, so you will need to stock the correct cleaning supplies.
Drying Performance
It relies on fan-assisted drying rather than a heating element. While energy-efficient, some plastics or concave items may come out slightly damp and require a quick towel dry.
Product Specs
| Dimensions | 37 x 26 x 25.5 inches |
| Type | Undercounter double drawer |
| Wash Cycles | Six |
| Speed | 60+ minutes |
| Gallons per Cycle | 3.44 (for both tubs at once) |

Hobart LXEH-2 Undercounter
Best Sanitizing Dishwasher
Sanitization is non-negotiable in the food service industry. The Hobart LXEH-2 is built specifically to meet the strictest health codes. It combines heavy-duty stainless steel construction with a powerful internal heater to ensure pathogens are destroyed.
Compact enough for pubs and hotel bars, this undercounter unit delivers consistent results. If you need a machine that guarantees inspection-ready dishes every single time, this is a strong contender.
What We Like
Built-In Booster Heater
Cold water doesn’t clean grease. This unit features a built-in booster heater that rapidly raises water temperature to sanitization levels (180°F). This eliminates the need for chemical sanitizers, saving you money on supplies.
Blazing Fast Cycles
It cleans a rack in just 109 seconds. That translates to roughly 32 racks per hour. Your bussers will be able to clear tables and restock the kitchen faster than ever.
Rugged Construction
Commercial gear gets banged around. The stainless steel body, tank, and door liner are designed to resist corrosion and denting, ensuring the machine lasts through years of hard use.
Double Filtration
Dirty water leads to dirty dishes. This model uses a double filtration system to trap food particles and sediment, keeping the wash water cleaner for longer periods during the shift.
What We Don't Like
Hard Water Sensitivity
Like many high-end commercial units, this machine is sensitive to scale. If you operate in an area with hard water, you must install an external water softener, or the heating elements may degrade quickly.
Product Specs
| Dimensions | 25.56 x 23.94 x 32.5 inches |
| Type | Undercounter |
| Wash Cycles | Not specified |
| Speed | 109 seconds cycle |
| Gallons per Cycle | 0.74 |

Farberware Professional Countertop Portable Dishwasher
Best Budget Choice
Let’s be clear: this is not for a busy restaurant kitchen. However, for an office breakroom, a tiny coffee kiosk, or a bed and breakfast, the Farberware Professional is a lifesaver. It sits right on the countertop and connects to a standard faucet.
It holds six place settings, making it perfect for small teams to clean up mugs and plates at the end of the day. It bridges the gap between hand-washing and installing a full-sized commercial unit.
What We Like
Zero Installation Hassle
This unit is portable and requires no plumbing modifications. You can hook it up to the sink when needed and disconnect it seconds later. It’s ideal for rented commercial spaces where you can’t alter the infrastructure.
Digital Controls
Despite the small size, it features a clear LED display. You can choose from seven different programs, including a “Baby Care” cycle for sanitizing and a “Glass” cycle for breakroom tumblers.
Compact Footprint
It takes up about as much space as a large microwave. In a cramped back office or a food truck with limited counter space, this compact design allows you to automate dishwashing without sacrificing your prep area.
Versatile Application
While we review this for business use, it doubles as a fantastic solution for RVs, dorms, or tiny apartments. It’s a versatile tool for any space-constrained environment.
What We Don't Like
Limited Capacity
It fits six place settings, which is great for a few people but useless for a crowd. It cannot fit large pots, baking sheets, or commercial prep bins.
Not a “True” Commercial Unit
It doesn’t meet the 90-second cycle standards of the industry. Cycles are closer to residential times (45 minutes to an hour). It also lacks the NSF certification required for commercial restaurant inspections.
Product Specs
| Dimensions | 21.7 x 19.7 x 17.2 inches |
| Type | Countertop |
| Wash Cycles | Seven |
| Speed | Between 45 and 110 minutes |
| Gallons per Cycle | N/A |

Blakeslee High Temperature Glasswasher
Best Commercial Glass Washer
If you run a bar, winery, or brewery, clean glass is your canvas. The Blakeslee High Temperature Glasswasher is designed specifically to handle delicate stemware while removing lipstick, pulp, and residue.
It fits neatly under the bar and features a sleek stainless steel aesthetic. More importantly, it uses high heat to sanitize, ensuring your beer retains its head and your wine tastes exactly as intended, without chemical aftertastes.
What We Like
High-Speed Bar Service
Bartenders can’t wait for glasses. This unit cycles in just two minutes, delivering up to 30 racks per hour. This rapid turnover is essential for Friday nights when your glassware stock is rotating fast.
Thermal Sanitization
By rinsing at 185°F, this machine kills bacteria and evaporates moisture quickly. Because it doesn’t rely on chemical sanitizers (like chlorine), you won’t get that swimming pool smell on your wine glasses.
Debris Management
Bar sinks get messy with garnishes. The triple filter system in this unit captures fruit seeds, citrus rinds, and cocktail umbrellas, preventing them from clogging the drain or recirculating onto clean glasses.
Cost-Effective Quality
For a dedicated high-temp glasswasher, the price point is competitive. It offers professional-grade cleaning results without the massive footprint of a door-type machine.
What We Don't Like
Glass-Specific Racking
While it can wash small plates, it is optimized for glass racks. It does not typically come with a cutlery basket, so you may need to purchase accessories if you plan to wash spoons and stirrers.
Door Latch
The magnetic door closure is convenient but can feel a bit light compared to mechanical latches. It requires a gentle touch to ensure it engages properly every time.
Product Specs
| Dimensions | 23.5 x 24 x 33.25 inches |
| Type | Glasswasher |
| Wash Cycles | Two |
| Speed | Two to three-minute cycles |
| Gallons per Cycle | 0.74 |

Hobart LT1-1 Low Temp Door Type Dishwasher
Best Eco-Friendly Dishwasher
For high-volume kitchens that are conscious of energy costs, the Hobart LT1-1 is a top contender. This is a “door-type” machine, meaning you slide racks in and out quickly at standing height.
As a low-temperature unit, it relies on chemical sanitizers rather than an energy-hungry booster heater. It is Energy Star certified and capable of washing a staggering 37 racks per hour, making it a favorite for diners and busy restaurants.
What We Like
Hard Water Handling
Scale buildup kills dishwashers. The LT1-1 features integrated delime notifications and anti-scale technology to keep the heating elements and spray arms free of mineral deposits. This extends the life of the machine significantly.
Precise Chemical Dosing
You don’t need to manually measure chemicals. The built-in peristaltic pumps automatically inject the exact amount of detergent, rinse aid, and sanitizer needed for each cycle. This prevents waste and ensures health code compliance.
Superior Coverage
Hobart uses revolving upper and lower rinse arms. This ensures water hits the dishes from every angle, eliminating blind spots where food might hide.
Self-Cleaning Strainer
The external scrap strainer collects food waste and self-flushes to prevent clogging. It keeps the wash water clean and reduces the frequency of manual cleanouts required by your staff.
What We Don't Like
Chemical Dependence
Because it washes at 140°F, you are tied to purchasing chemical sanitizers forever. While you save on electricity, you add a recurring supply cost to your budget.
Short Warranty
The standard warranty is one year. Given the high cost of repair parts for commercial units, we always recommend maintaining a strict cleaning schedule to avoid issues once the warranty expires.
Product Specs
| Dimensions | 24 x 26 x 68 inches |
| Type | Door style |
| Wash Cycles | One |
| Speed | Less than 90 seconds |
| Gallons per Cycle | 1.7 |

Fisher Paykel Professional Series Dishwasher
Most Quiet
The Fisher Paykel Professional Series fits a specific niche: the boutique business. If you run a high-end spa, a private club, or an executive lounge, you don’t want the clatter of industrial machinery.
This unit offers the same double-drawer convenience as other Fisher Paykel models but with a focus on silence and style. While it lacks the raw speed of a Hobart, it offers superior flexibility and near-silent operation for guest-facing areas.
What We Like
Workflow Flexibility
The DishDrawer system allows you to run small loads continuously. You can wash coffee cups in the top drawer while the bottom drawer remains open for loading. This keeps dirty dishes off the counter and out of sight.
Adjustable Racking
The interior racks are highly adjustable. You can fold down tines to fit larger bowls or adjust the height to accommodate tall stemware. This customization is great for venues with varied serving ware.
Extreme Efficiency
This is an eco-champion. It uses roughly 276 kWh of energy per year and minimal water per cycle. For businesses looking to lower their carbon footprint (and utility bills), this is a smart choice.
Certified Sanitization
Despite being quieter, it still features a sanitization cycle that kills 99.9% of bacteria. It’s safe for food service and excellent for sanitizing baby bottles or healthcare items.
What We Don't Like
Slow Cycles
This is the slowest machine on our list. A “fast” cycle is 46 minutes, and a normal cycle is over two hours. It is not suitable for a restaurant that needs to flip tables every hour.
Sensitive Electronics
The control panel is sophisticated but can be sensitive. Some users report accidental button presses or “child lock” engaging unexpectedly. It requires a bit of learning to master the interface.
Product Specs
| Dimensions | 22.75 x 23.8 x 36.4 inches |

FAQs
Can I Use a Commercial Dishwasher in My House?
Technically yes, but it isn’t practical. Commercial units require specialized electrical wiring (often higher voltage), dedicated plumbing, and possibly a ventilation hood. They also lack the insulation of home models, making them loud and hot to touch.
Do Commercial Dishwashers Need a Hood?
High-temperature machines usually require a Type II condensate hood to remove steam and heat. Low-temperature chemical machines often do not require a hood, but local building codes vary, so always check with your inspector first.
Do Commercial Dishwashers Dry the Dishes?
Yes, mostly through “flash drying.” High-temp machines leave the dishes so hot (180°F) that water evaporates almost instantly when the rack is pulled out. Low-temp machines may take slightly longer to air dry since the plastic retains less heat.
How Often Should a Commercial Dishwasher Be Cleaned?
You should drain and rinse the scrap screens at the end of every shift. Deep cleaning and checking the wash arms for clogged nozzles should happen once a day. Deliming (removing scale) should occur weekly or monthly depending on your water hardness.
Can You Put Plastic in a Commercial Dishwasher?
Yes, but place lightweight plastics in a specific rack or weigh them down with a mesh cover. The water pressure in commercial units is so high it can flip light containers, filling them with dirty water.
How Long Do Commercial Dishwashers Last?
With proper maintenance, a quality commercial dishwasher should last 10 to 15 years. Neglecting daily cleaning or deliming can cut that lifespan in half.
Does a Commercial Dishwasher Need a Drain Pump?
It depends on your plumbing. If your drain is on the floor (gravity drain), you likely don’t need a pump. If your drain pipe is higher than the machine’s outlet (in the wall), you absolutely need a model with a built-in drain pump to push the water up and out.
