Choosing a Commercial Dishwasher

Must Read

Are you having difficulties with your current commercial dishwasher, or do you want to buy one for the first time? Commercial dishwashers ensure that you have clean glassware and dishware in your restaurant when needed. Investing in a high-quality one will also help you comply with your local sanitation codes.

Unlike domestic dishwashers, commercial ones have high-temperature settings and can handle more dishes. They also require less water and less effort to clean dishes more efficiently. While you may rely on a sink to handle dirty dishware, the sink won’t be effective in a busy kitchen.

Your commercial dishwasher should have the correct temperature settings and capacity for your kitchen size. It should also fit in your kitchen space and fall within your energy consumption limits. Here are factors you should review when choosing one:

Type of Commercial Dishwasher

Get a glasswasher if you have an influx of glassware in your bar. A glasswasher isn’t ideal for dishware because of its smaller capacity and cleaning specifications.

A standard dishwasher fitted under a kitchen counter would work well in a small restaurant. Most of them come with 20-inch by 20-inch plastic racks that can handle up to 750 dishes in an hour.

Invest in a rack machine dishwasher to tackle a large volume of dishware and glassware. The appliance would also be ideal for an establishment serving 100 to 150 meals every hour.

A conveyor dishwasher would be ideal for a large-scale restaurant or bar. The washer can handle as little as 5,400 dishes and a maximum of 28,000 dishes every hour. Though it operates faster, the appliance requires a lot of space and is quite costly.

Temperature Settings

Commercial dishwashers come with either high or low-temperature settings. Both types work with rinsing chemicals and detergents to clean dishes but have different sanitizing mechanisms.

A high-temperature dishwasher will wash dishes at 150 to 160 degrees Fahrenheit and rinse them at 180 degrees Fahrenheit. The appliance comes with a condensate hood to cope with the intense heat. It dries dishes faster and doesn’t require any sanitizer to rinse the dishes.

On the other hand, a low-temperature dishwasher relies on chemical sanitizers to clean dishes. Its washing and rinsing cycles range from 120 to 140 degrees Fahrenheit. Unlike its counterpart, a low-temperature washer consumes less energy and requires low setup costs.

Ease of Operation

Most commercial dishwashers come fitted with racks and have different settings for ease of use. Think about the effort required to load and run the appliance in your kitchen before buying it. You should also find out if there are any additional features needed for the machine to be efficient.

Check the decibel ratings on the dishwasher to determine whether it’s usually loud when operating. Most dishwashers have a decibel rating ranging from 46 to 60 dB. If you want a quieter washer, get one with a decibel rating between 39 and 45 dB.


Consider the upfront and running costs of the commercial dishwasher before getting it. These costs depend on the size and capacity of the machine.

High-temperature ones require both high upfront and running costs since they consume a lot of power. With low-temperature washers, you’ll need to buy sanitizers and replace any damaged dishware often.

Get the right type and style of the dishwasher for your utensils to avoid breaking them. You should also avoid using a low-capacity washer when you have high dishware cleaning demands.

Warranty and Support

Review the manufacturer warranty, acceptable use agreements, and terms/conditions for the dishwasher. This information helps you determine whether the liability of repairs and replacement will be on you. Most commercial dishwashers come with a warranty valid for one to three years and varying terms.

Reach out to the manufacturer’s support staff and inquire about their refund policy before you commit. Find out whether they can give you a temporary replacement when your broken dishwasher is being fixed. You should also ask about the availability of spare parts for long-lasting performance.

Speed and Sanitation

The best commercial dishwasher should have the capacity to clean dishes fast without compromising on food safety. It should complement your current food safety measures to improve your credibility.

A high-temperature dishwasher would be suitable for an environmentally-friendly kitchen. This appliance doesn’t rely on chemicals to keep your dishes clean. If you’re looking for a tailor-made dishwasher to suit your space requirements and budget, click now & save.

Check the length of the wash cycle on the appliance before getting it. Commercial dishwashers have a wash cycle that ranges from one to two minutes. You should also review the number of dishes the machine can handle in one load.

Energy Efficiency

Commercial dishwashers rely on water and energy as the primary resources to clean dishes. Be prepared to spend more on these resources if you’re investing in a high-capacity and high-volume model.

Check whether the dishwasher has low-energy settings that you can activate when it’s idle to save energy. Opt for one with low-water usage capabilities to reduce your water bills. You should also have proper drainage in place to handle the water discharge.

One way to determine whether the washer is energy efficient is to look for the Energy Star label. The Energy Star certification implies that the appliance is 40 percent more energy efficient. It also suggests that the machine consumes 40 percent less water.

Ensure that the electrical service in your establishment matches the electrical requirements of the dishwasher. Most commercial dishwashers require a minimum of 208v to run.
