Commercial Dishwasher: Best Practices for Maintenance and Disposal

If you own or operate a restaurant, hotel, or any other type of food service establishment, you know how important it is to have clean and sanitary dishes. One of the most important pieces of equipment in any commercial kitchen is the dishwasher. A commercial dishwasher is designed to handle large volumes of dishes quickly and efficiently, but it's important to know what should be done with it at the end of each day to keep it running smoothly.

Commercial dishwashers use a combination of detergents, rinse aids, and sanitizers to produce clean and well-sanitized dishes. If these chemicals are not used correctly, customers may complain about dirty or unsanitary dishes. In addition, commercial dishwashers have a number of moving parts that need to be cleaned and maintained regularly to ensure that they are working properly.

In this article, you will find everything you need to know about what should be done with a commercial dishwasher at the end of each day. From cleaning the machine itself to properly using detergents and sanitizers, we will cover all the steps you need to take to keep your dishwasher running smoothly and your dishes clean and sanitary.

Maintenance

Daily Maintenance

Keeping a commercial dishwasher in good condition requires daily maintenance. After each cycle, the dishwasher should be cleaned and allowed to air dry. This prevents bacteria growth and ensures that the machine is ready for the next load.

Additionally, the dishwasher screens, filters, and baskets should be removed and cleaned in the sink using a soft-bristled brush, detergent, and warm water. It's important to clear the filter of any food particles to prevent clogging of the drain and unpleasant odors.

Finally, every day, the dishwasher's vital levels should be checked. These include water temperature, pressure, and chemical dispenser operation. Any issues should be addressed immediately to prevent further damage.

Weekly Maintenance

On a weekly basis, the dishwasher should be inspected for any visible signs of wear and tear. This includes checking the tightness of the seals, inspecting the condition of the components, and diagnosing any hidden problems.

Additionally, the dishwasher should be descaled in case of a lime buildup. This can be done using a commercial descaling solution or a mixture of vinegar and water. Follow the manufacturer's instructions for best results.

Finally, the dishwasher's chemical dispensers should be checked for proper operation. If they are not working correctly, they should be replaced immediately.

Monthly Maintenance

Monthly maintenance of a commercial dishwasher involves a more thorough inspection of the machine. A certified commercial dishwasher technician should be called in to perform this maintenance. The technician should inspect the machine and check the condition of the components, diagnose hidden problems, and replace parts if necessary.

It's also important to check the dishwasher's water quality and adjust the chemical dispensers accordingly. This can be done using a water quality test kit and the manufacturer's recommended chemical levels.

Finally, the dishwasher's solenoid valve filter should be cleaned to prevent clogging and ensure proper operation.

By following these maintenance guidelines, a commercial dishwasher can be kept in good condition and provide consistent, high-quality cleaning results.

Repairs

Commercial dishwashers are a crucial part of any food service operation. When they break down, it can cause major disruptions and delays. Fortunately, most issues with commercial dishwashers can be resolved with proper troubleshooting and part replacement. Here are some steps to take when a commercial dishwasher needs repair.

Troubleshooting

Before calling a professional for repairs, it's important to troubleshoot the issue to determine if it's a simple fix. Here are some common issues and troubleshooting steps:

Replacing Parts

If troubleshooting does not resolve the issue, it may be necessary to replace parts. It's important to use OEM (original equipment manufacturer) parts to ensure proper fit and function. Here are some common parts that may need to be replaced:

• Heating element
• Spray arms
• Water inlet valve
• Float switch
• Thermostat

Replacing parts can be complex and should be done by a professional technician with experience in commercial dishwasher repair. Attempting to replace parts without proper knowledge and tools can cause further damage and safety hazards.

Cleaning

Keeping a commercial dishwasher clean is essential to ensuring its longevity and preventing the spread of germs. Here are the steps to follow for a thorough cleaning:

Pre-Cleaning

Before beginning the cleaning process, it is important to pre-clean the dishwasher. This involves removing any leftover food particles or debris from the machine. Here are some steps to follow:

• Remove all racks and trays from the dishwasher.
• Scrape off any leftover food particles or debris from the machine using a scraper or brush.
• Use a damp cloth to wipe down the interior of the dishwasher, including the wash and rinse arms, as well as the rubber gaskets, if any.

Cleaning Process

Once the pre-cleaning is complete, it is time to start the actual cleaning process. Here is what to do:

• Fill the dishwasher with water.
• Add a commercial dishwasher cleaning solution. Follow the instructions on the package, and allow the cleaner to sit for at least one hour.
• Run a full wash cycle.
• Inspect the interior of the machine to see if any lime buildup has been removed.

Post-Cleaning

After the cleaning process is complete, it is important to take a few additional steps to ensure the dishwasher is fully cleaned and ready for use. Here are some steps to follow:

• Remove any remaining cleaning solution from the dishwasher.
• Run a rinse cycle to remove any remaining debris or cleaning solution from the machine.
• Inspect the wash and rinse arms to ensure they are clean and free of any debris.
• Wipe down the exterior of the machine with a damp cloth.

By following these steps, a commercial dishwasher can be kept clean and in good working condition for years to come.

Safety

Proper Use

Proper use of commercial dishwashers is crucial to maintain the safety of both the operator and the customers. The operator should be trained on how to use the dishwasher properly, including loading and unloading dishes, adding detergent, and operating the machine. The following are some tips for proper use:

• Always follow the manufacturer's instructions for loading and unloading dishes.
• Never overload the dishwasher, as this can result in poor cleaning and potential safety hazards.
• Use the appropriate amount of detergent for each wash cycle.
• Regularly clean the dishwasher to prevent buildup of food particles and bacteria.
• Check the water temperature to ensure it is at the recommended level for washing and rinsing cycles.

Emergency Procedures

Despite proper use and regular maintenance, emergencies can still occur while using commercial dishwashers. Operators should be trained on emergency procedures to ensure the safety of all involved. The following are some emergency procedures to keep in mind:

• Know the location of the emergency shut-off switch and how to use it.
• In case of a fire, turn off the power to the dishwasher and use a fire extinguisher to put out the flames.
• If a chemical spill occurs, turn off the power to the dishwasher and evacuate the area immediately.
• In case of an injury, provide first aid and seek medical attention if necessary.

By following proper use and emergency procedures, operators can ensure the safety of themselves and their customers while using commercial dishwashers.

Conclusion

When it comes to commercial dishwashers, there are a few things that should be kept in mind. First and foremost, it is important to ensure that the dishwasher is properly maintained and cleaned on a regular basis. This will help extend its lifespan and ensure it continues functioning properly.

Additionally, when it comes time to dispose of a commercial dishwasher, a few options are available. One option is to sell it for resale. This can be done by contacting a dealer or other reseller who specializes in commercial kitchen equipment. Another option is donating the dishwasher to a non-profit organization or a local school or community center where it can be used for meals.

If the commercial dishwasher is not in a reusable condition, recycling it is the best option. These appliances are built with many recyclable materials, including steel, aluminum, and copper. Recycling a commercial dishwasher is not only environmentally responsible but can also help reduce waste and conserve resources.
