Understanding the Basics of Commercial Dishwasher Operation

Anyone who owns any kind of food, restaurant, café, bar, school, or healthcare facility knows how important a commercial dishwasher can be for everyday maintenance, customer satisfaction, and overall cleanliness.

As a powerful machine that can sanitise glasses, cups, trays, utensils, and any other kind of serving tool, commercial dishwashers simply take detergent solutions and provide a fully sanitised, finalised result in a timely and efficient manner.

So how does one exactly use a commercial dishwasher? Let's look at it in-depth below.

Key Components of a Commercial Dishwasher

To properly operate a dish machine, it's crucial to understand its key components. The user manual is an excellent resource for identifying these parts and their functions.

The wash arms and rinse arms are responsible for distributing water and detergent throughout the machine during the cleaning process. These arms rotate to ensure even coverage.

Let's not forget the overflow tube, a real lifesaver that keeps water from spilling over by smartly funnelling any extra into the drain. Familiarising yourself with these key parts will help you operate and maintain your commercial dishwasher effectively.

Steps to Operate a Commercial Dishwasher

It is of utmost importance to always double-check if the drain is securely closed before placing any items into the commercial dishwasher. This precaution ensures that no water or detergent will leak out during the washing process, preventing any potential accidents or damage. 

Once you have confirmed that the drain is closed, you can proceed with operating the dishwasher. To do so, simply press and hold the fill button until the machine is completely filled with water. 

You can easily determine if the machine is filled by observing the water level, which should be approximately two inches from the bottom of the pan. After ensuring that the dishwasher is filled, it is crucial to check the temperature to ensure that it falls within the appropriate operating range. 

The water temperature should ideally be maintained between 140 and 155 degrees Fahrenheit. Additionally, it is essential to verify that there is an adequate amount of detergent present in the dishwasher. 

If necessary, add in a rinse additive and sanitizer to enhance the cleaning process. Following these steps will ensure the optimal functioning of the commercial dishwasher and guarantee that your dishes are thoroughly cleaned and sanitised.

Draining Process for Commercial Dishwashers

Making sure your commercial dishwasher drains properly is key to keeping it running smoothly and staying spotless. Here's a step-by-step guide on how to drain your machine and clean its components.

Switching Off the Machine and Opening the Drains

To begin the draining process, turn off the machine by pressing the power button. Then, open the dishwasher's door and locate the drain lever or manual drains.

Lift the drain lever or open the manual drains to allow the water to empty from the dishwasher's tank(s). This step is crucial for preventing water from sitting in the machine and potentially causing damage or bacterial growth.

Cleaning the Wash and Rinse Arms

While the machine is draining, take the opportunity to clean the wash arms and rinse arms. Inspect these components for any clogs or debris that may have accumulated during use.

Remove the arms and thoroughly clean them, paying special attention to the spray nozzles. If your machine has rubber gaskets, be sure to clean those as well. Keeping these components clean ensures optimal performance and helps prevent damage to the dishwasher.

Removing Baskets, Scrap Screens, and Pump Screens

Once the dishwasher is drained and you've cleaned any remaining scraps from the machine walls, remove the strainer pans and strainer baskets. Give these components a thorough wash and rinse.

Next, locate and remove the pump screens. Take the pump intake strainer to the sink for cleaning. Removing and cleaning these screens and baskets helps prevent clogs and ensures that your commercial dishwasher continues to operate efficiently.

Deep Cleaning of Commercial Dishwasher

After draining your commercial dishwasher, it's time for a deep clean. This section covers the in-depth cleaning procedures for various parts, including the interior, drain screens, tank, curtains, and overflow tube.

Cleaning the Interior, Drain Screens, and Tank

Start by thoroughly cleaning the dishwasher's interior from top to bottom, including all the nooks and crannies. Remove any remaining food debris and give the inside a good scrub.

Next, focus on the drain screens and tank. Remove the drain screens and give them a deep clean, ensuring that they are free of any debris or buildup. For the tank, remove the pump cover and hose it down, making sure to clean out any food particles or grime.

Washing Curtains and Overflow Tube

Don't forget about the curtains and overflow tube. Remove these components from the dishwasher and give them a thorough wash.

For the curtains, scrub them down and rinse them well. You can even run them through the dishwasher once it's clean for extra measure. As for the overflow tube, remove it from the tank, clean it out, and give it a good rinse before reinstalling it.

Reassembling and Exterior Cleaning of Commercial Dishwasher

After a thorough deep clean, it's time to put your commercial dishwasher back together and give the exterior some TLC. Here are some guidelines on reinstalling all the parts and tips for cleaning the outside of your machine.

Reinstalling All Parts After Cleaning

It's imperative to clean your dishwasher at the end of the day to prolong its lifespan and ensure maximum efficiency the next day it's used. First, remove the racks from the dishwasher and take out the scrap tray.

Discard all food traps caught in the scrap tray and give it a good clean by scrubbing it with a sponge and rinsing it under running water.

Once you've cleaned all the components, it's time to reinstall them. Make sure to put everything back in its proper place, including the strainer pans and baskets, upper and lower wash arms, and overflow tube. Double-check that all parts are fully seated and secure.

Cleaning the Exterior of the Machine

Don't neglect the exterior of your commercial dishwasher. Wipe down the outside of the machine using a mild cleanser and a soft cloth.

Pay attention to areas that may collect grime or fingerprints, such as the dishwasher door handle and control panel. A clean exterior not only looks more professional but also helps prevent the spread of germs and bacteria.

Maintaining Cleanliness of Commercial Dishwasher

Keeping your commercial dishwasher clean is an ongoing task. In this section, we'll discuss the importance of daily cleaning procedures and how often you should give your machine a thorough clean.

Daily Cleaning Procedures for Commercial Dishwasher

If you want your commercial dishwasher to keep running like a champ, making a daily cleaning routine part of your schedule is key. Start by removing any visible food debris and giving the interior a quick wipe-down.

Don't forget to clean the spray arms and filters to prevent clogs and ensure optimal performance. Most commercial dishwashers offer manuals with detailed instructions on everything from parts removal to the actual cleaning.

However, if you do not have the user manual, there is no need to panic. You can follow the general guidelines that apply to pretty much all the different types of commercial dishwashers.

Frequency of Cleaning a Commercial Dishwasher

So, how often should you give your commercial dishwasher a thorough clean? The answer depends on how frequently you use the machine.

As a general rule of thumb, aim to deep clean your dishwasher at least once a week. However, if your establishment is particularly busy or if you notice any signs of buildup or odors, you may need to clean it more often.

By staying on top of your cleaning routine and addressing any issues promptly, you can extend the life of your commercial dishwasher and ensure that it continues to deliver sparkling clean dishes day after day.

Key Takeaway: 

Keep your commercial dishwasher running smoothly by following a daily cleaning routine, deep cleaning it weekly or as needed, and knowing how to properly drain and maintain all parts. A clean machine ensures sparkling dishes and prolongs its life.
