How To Choose A Commercial Passthrough Dishwasher That Will Fit Your Business' Needs Restaurant Equipment Online

When you're looking for a commercial passthrough dishwasher for your restaurant, you'll want to make sure you're choosing one that's going to work well for your business. There are a lot of factors to consider—from cost and efficiency to ease of use and cleaning.

However, there are many great brands and models to choose from, each with their own pros and cons. In this article, we'll compare some of the best commercial pass-through dishwashers so you can see how they stack up against each other.

What Is A Commercial Pass Through Dishwasher?

A passthrough dishwasher is a type of freestanding commercial dishwasher with a lift-up hood (top cover), intended for efficient and high-volume dishwashing. In fact, most commercial kitchens have their dishwashers set up to automatically start as soon as the hood is closed with a new load of dirty plates inside.

This cuts down on time spent cleaning dishes by hand, and cleaning large amounts of dirty dishes at one time. These dishwashers are perfect for use in restaurants, hospitals, schools, resorts and other commercial establishments that require their kitchen utensils to be spotless at all times.

Why Should You Consider Installing One?

If you have a busy restaurant or cafe with lots of dishes coming through your doors every day, then installing a commercial passthrough dishwasher could be an excellent investment in time savings and efficiency! 

With ever-rising staff wages, hiring someone purely to clean dishes can be quite expensive. And when you factor in the time and energy it takes to hire and train new staff members, it's no wonder that so many restaurants are having trouble keeping up with their dirty dishes.

On the other hand, a commercial passthrough dishwasher can pay itself off in months (or weeks!) With just one of these appliances, you'll be able to save time and money by bringing the power of automation into your kitchen. 

And the best part? You don't need any special training or skills to use one! All you need is an understanding of how they work and how they can benefit your business.

What Are The Things To Look For When Buying A Commercial Passthrough Dishwasher?

When buying a commercial dishwasher, there are many factors to consider. The following are some of the most important things to look for when choosing the best commercial dishwasher for your business.

Material of Components

The material of the dishwasher and its components is very important. While the material of the dishwasher can affect its price, it will also greatly impact its durability and longevity.

Commercial passthrough dishwashers need to be durable and able to withstand constant use. That’s why higher end dishwashers are made from stainless steel. However, some may include plastic components such as rinse arms, filters and plastic screws to cut down on costs. That’s why almost all dishwasher brands have models that offer a combination of these materials in their product range, allowing you to get the best of all worlds at an affordable price point.

Basket Size & Clearance Height

The basket size is another important consideration when buying a commercial pass-through dishwasher. Most of them have 500x500mm size racks.

You also need to make sure that there is enough clearance height or loading height for your dishes and utensils. Always check the internal dimensions of prospective dishwashers to make sure your plates, pots and pans will fit without any clearance issues!. This can be especially important if you have large plates or pots and pans to wash.


You have to consider power requirements when buying commercial kitchen equipment. Most of the passthrough dishwashers run on three phase power, but entry level units may run on single phase (10-15Amp) power. Remember that more power means the dishwasher can warm its rinse water faster and wash plates more effectively. So the trade off for lower power consumption is a higher time requirement to clean the dishes!

The best way to make sure your commercial pass-through dishwasher is compatible with your existing electrical system is to consult with an electrician. They will be able to give you an accurate assessment of whether or not the dishwasher will fit into your existing setup and how much it will cost to install.

Moreover, if you are looking to save on electricity bills, dishwashers from Hobart can be a great option. They are incredibly economical because they are more efficient and use less electricity than other brands, which means that you will be saving money on your electricity bill every month.

Steam Extraction:

Keep in mind that under most Australian council regulations, you will need to install an overhead exhaust canopy if your appliance is rated over 8kW, which most passthrough dishwashers are.. But if you want to skip the hassle, you can select one of the models with built-in canopies!

Although these models are not the cheapest, they are a lot cheaper than installing a dedicated extraction canopy above the dishwasher.

Sealed Hood

Some dishwashers are open at the back of their hoods, which can create problems with heat loss, water spillage and evaporation via steam loss. Other models, like the Hobart range, are completely sealed so you don't have to worry about moisture getting out or in. This can help save you money on running costs later on down the line. Further down, we have included a handy chart of various models and their power consumption figures. Thanks to their better insulation properties, including a sealed hood, it's no wonder that the Hobart models require less power to clean the same amount of dishes as other brands.


Like having a sealed hood, body Insulation is also one of the most important factors to consider when buying a commercial dishwasher. Some are insulated by way of double skinned walls on all sides, while others are insulated only on the roof or base of the unit. You want something that has maximum insulation - a completely insulated body with insulated doors, and double skinned walls. This will help reduce energy costs and ensure your machine runs smoothly for many years to come.

Commercial Dishwasher Installation Requirements

When you're installing a commercial dishwasher in your kitchen, there are some basic requirements you'll need to make sure of. 

Water Pressure

Have you had your water pressure tested?

Low water pressure will not allow the machine to work correctly, so it's important to make sure that your building's plumbing system has enough flow rate to accommodate your new dishwasher. Most entry level dishwashers require at least 300kPa constant water flow pressure to operate.

If you have an undersized plumbing system—one with insufficient flow rate—you'll need to retrofit a pump in some cases. Or opt for passthrough dishwasher models that have built-in booster water pumps.

Water Hardness

Not all water is created equal. 

If you have hard water, it can be tough on your dishwasher!

Hard water is water that contains a high concentration of minerals like calcium and magnesium. This means that limescale can quickly build up inside the dishwasher, causing inefficient operation, reduced cleaning performance and increased energy consumption

In hard water areas, we recommend that you install a water softener as standard practice when you're installing a new commercial dishwasher. They break down and filter the limescale in the water before it enters the machine, keeping your equipment working properly! This can often be necessary in regional areas and those which use bore water.

Some Of The Best Passthrough Dishwasher Brands

Now that you know the basics, let's dive into some of the best commercial dishwashers on the market. These brands have a good reputation, and many customers have been satisfied with their performance.
