Factors to Consider When Choosing a Commercial Dishwasher

Commercial dishwashers are essential equipment in any restaurant or foodservice establishment. They are designed to handle large volumes of dishes, utensils, and glassware quickly and efficiently, saving time and labor costs. When choosing a commercial dishwasher, there are several factors to consider to ensure that you get the right machine for your needs. Here are some of the most important factors to keep in mind:

Size and Capacity

The size and capacity of the dishwasher you choose will depend on the size of your establishment and the volume of dishes you need to wash. A small restaurant may only need a low-capacity undercounter dishwasher, while a large banquet hall may require a high-capacity conveyor dishwasher. Consider the following when choosing the size and capacity of your dishwasher:

• The number of dishes used per meal
• The number of meals served per day
• The available space in your kitchen

Energy Efficiency

Energy efficiency is an important consideration when choosing a commercial dishwasher. Not only will an energy-efficient machine save you money on your utility bills, but it will also reduce your carbon footprint. Look for a dishwasher with an ENERGY STAR rating, which means it meets strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. Consider the following when evaluating the energy efficiency of a dishwasher:

• The amount of water used per cycle
• The amount of energy used per cycle
• The type of heating element used

Ease of Use

An easy-to-use dishwasher will save your staff time and frustration, allowing them to focus on other tasks. Look for a machine with intuitive controls, easy-to-load racks, and a simple maintenance process. Consider the following when evaluating the ease of use of a dishwasher:

• The type of controls (digital, analog, touch screen)
• The loading and unloading process
• The cleaning and maintenance process

Maintenance and Repair

Like any piece of equipment, a commercial dishwasher will require regular maintenance and occasional repairs. Look for a machine with a reliable warranty and easy-to-find replacement parts. Consider the following when evaluating the maintenance and repair process for a dishwasher:

• The length and coverage of the warranty
• The availability of replacement parts
• The ease of accessing and repairing the machine

How to Properly Use a Commercial Dishwasher

Preparation

Before using a commercial dishwasher, it is important to make sure that all dishes and utensils are properly scraped and rinsed to remove any food debris. This will prevent clogs in the machine and ensure that dishes come out clean. It is also important to check the machine's detergent, rinse aid levels, and refill as necessary.

Loading and Unloading

When loading a commercial dishwasher, it is important to arrange dishes and utensils properly to ensure that they get cleaned thoroughly. Heavy items should be placed on the bottom rack, and lighter items on the top rack. Utensils should be placed in their designated holders to prevent them from falling through the racks. Once the machine has completed its cycle, dishes should be unloaded carefully to prevent breakage.

Operating the Machine

Operating a commercial dishwasher is a simple process. First, select the appropriate wash cycle based on the dish type. Next, load the dishes into the machine and close the door. Press the start button and allow the machine to complete its cycle without interruption. It is important never to interrupt the wash program to ensure that dishes are properly cleaned.

Cleaning and Maintenance

Regular cleaning and maintenance of a commercial dishwasher is essential to keep it running smoothly and to ensure that dishes come out clean. It is important to clean the machine's filters and wash arms regularly to prevent clogs. The machine should also be descaled periodically to remove any mineral buildup. Additionally, it is important to inspect the machine's seals and gaskets regularly to ensure that they are in good condition and not leaking.

By following these simple steps, anyone can properly use a commercial dishwasher to ensure that dishes come out clean and sparkling every time.

Common Issues with Commercial Dishwashers

Commercial dishwashers are essential for any restaurant, catering service, or other food industry business. However, like any other appliance, they can develop problems that can affect their performance. In this section, we will highlight some of the most common issues that arise with commercial dishwashers.

Leaks and Drainage Issues

One of the most common problems that commercial dishwashers develop is leaking. Leaks can occur for various reasons, such as a damaged door gasket, a clogged drain, or a malfunctioning pump. If you notice any water pooling around the dishwasher or if you see any signs of water damage, you should call a professional technician to diagnose and repair the issue.

Another common issue with commercial dishwashers is drainage problems. If the dishwasher is not draining properly, it could be due to a clogged drain hose, a blocked filter, or a malfunctioning pump. A technician can inspect the dishwasher and identify the root cause of the problem.

Clogged Spray Arms

Spray arms are responsible for distributing water throughout the dishwasher to clean dishes. Over time, these arms can become clogged with food particles, grease, and other debris. If the spray arms are not functioning correctly, it can lead to poor cleaning performance. A technician can clean the spray arms and ensure that they are working correctly.

Broken Heating Elements

Heating elements are responsible for heating the water in the dishwasher to the appropriate temperature to clean dishes effectively. If the heating elements are broken, the dishwasher cannot clean dishes correctly. A technician can diagnose and replace any faulty heating elements.

Electrical Problems

Commercial dishwashers rely on electricity to operate, and electrical problems can cause a range of issues. If the dishwasher is not turning on, it could be due to a faulty power cord, a tripped circuit breaker, or a malfunctioning control board. A technician can diagnose and repair any electrical issues with the dishwasher.

Conclusion

Commercial dishwashers are a crucial component of any restaurant or food service establishment. They save time, money, and effort by cleaning dishes, glasses, pots, and pans quickly and efficiently. There are different types of commercial dishwashers, including door type, conveyor type, and undercounter dishwashers. Each type has its advantages and disadvantages, depending on the business's specific needs.

One of the main benefits of a commercial dishwasher is its high capacity. It can process between 30 to 350 dish and flatware racks every day, making them great for localized operations like mom-and-pop restaurants. Additionally, commercial dishwashers are designed to clean dishes fast, which is essential in a busy restaurant environment.

Another advantage of commercial dishwashers is that they are easy to use. They come with user-friendly controls that allow restaurant staff to quickly and easily load, wash, and unload dishes. However, it is important to keep in mind that commercial dishwashers are often more expensive than other dishwasher types. They also use more energy and water, which can increase utility costs over time.

In conclusion, a commercial dishwasher is a valuable investment for any restaurant or food service establishment. Cleaning dishes quickly and efficiently saves time, money, and effort. When choosing a commercial dishwasher, businesses should consider their specific needs and budget to select the best option for their operation.
