7 Common Mistakes People Make When Using a Commercial Dishwasher

Do you dread the thought of cleaning your dishes by hand? If so, a commercial kitchen equipment like the dishwasher is an answer to your prayers. With a dishwasher, you can quickly and easily clean up all those dirty pots and pans without any effort. But did you know that there are some common mistakes people make when using a dishwasher? From loading it wrong to not pre-rinsing dishes properly, these errors can cost you money in wasted energy or even damage your machine. In this article, we'll look at five common mistakes people make when using their dishwashers – so that you don't have to!

7 Mistakes People Make When Using a Dishwasher

Let's dive in and look at the five most common mistakes people make when using their dishwashers:

1. Loading the Dishwasher Incorrectly

Loading the dishwasher incorrectly can lead to dishes not coming out clean and damage the dishwasher. Some common mistakes people make when loading the dishwasher include the following:
  • Overloading the dishwasher: This can prevent the dishwasher's spray arms from reaching all dishes, resulting in dirty dishes.
  • Need to arrange dishes properly: Dishes should be loaded with the filthy side facing the spray arm and with enough space between them for water to circulate.
  • Not stacking dishes correctly: Plates and bowls should be stacked on the lower rack, while cups and glasses should be placed on the upper rack.
  • Not placing dishes securely: Dishes should be securely placed in the racks to prevent them from moving around during the wash cycle.
  • Need to load the dishwasher's cutlery basket correctly: Spoons and forks should be placed with the handles down, and knives should be placed with the blade facing down for safety.
By loading the dishwasher correctly, you can ensure that your dishes come out clean and that your dishwasher runs efficiently.

2. Not Pre-Rinsing Dishes Properly

Pre-rinsing dishes properly before loading them into the dishwasher can lead to dirty dishes and clog the dishwasher's filters and spray arms. In addition, food debris left on plates can prevent the dishwasher from cleaning them effectively. Here are some tips for pre-rinsing dishes properly:
  • Scrape off any large food particles and debris from dishes using a scraper or a brush if needed.
  • Use warm water to rinse dishes, which will help to loosen any remaining food debris.
  • Run water over dishes, ensure all sides and surfaces, and pay extra attention to soiled areas such as the bottom of pots and pans.
  • Avoid using hot water when pre-rinsing dishes, as it can cause food particles to harden and become more difficult to remove.
By pre-rinsing dishes properly before loading them into the dishwasher, you can ensure that your dishes come out clean and that your dishwasher runs efficiently.

3. Not Using the Right Detergent for Your Commercial Dishwasher

Several issues arise if the incorrect kind of detergent is used in a commercial kitchen equipment dishwasher. For instance, applying too much detergent can result in excessive suds, which can harm the dishwasher or limit the cleaning effectiveness of the appliance. However, using a detergent that isn't made for commercial dishwashers can also lead to issues, such as clogging the machine's filters and spray arms, which reduces the cleaning effectiveness. So instead, use a detergent designed exclusively for industrial dishwashers and abide by the manufacturer's dose recommendations to prevent these problems.

Choosing the Right Detergent for a Commercial Dishwasher: Some Advice

Following are some suggestions for choosing the ideal detergent for a commercial dishwasher:
  • Look in the dishwasher's manual for information on the kind of detergent that is suggested for the appliance.
  • Look for a specially made detergent to get the best results in a commercial dishwasher's high-temperature, high-pressure conditions.
  • If you have hard water, seek a detergent with water-softening agents to assist in avoiding mineral buildup in the machine. But, again, take into account the type of water you're using.
  • Look for detergents that have earned NSF certification, which proves they adhere to strict health and safety requirements.
  • Read user reviews to learn more about how well the detergent performs and whether any complaints have been made about it.
  • Prices for detergents can vary greatly, so shop around to find a cost-effective and effective solution.

4. Not Training Staff Properly

Several problems arise if employees are not adequately trained in using and maintaining commercial dishwashers. Some such issues include: Improper dish loading: If staff aren't loading dishes correctly, cleaning performance will suffer, and cycle times will increase. Improper use of detergents: Staff may use too much or too little detergent, which can affect the machine's cleaning performance and potentially cause damage to the dishwasher. Ignoring safety procedures: Staff may need to be aware of the potential hazards of operating a commercial dishwasher, such as scalding from hot water or chemical burns from detergents. Safe Work Australia classifies scalding and hazardous chemical exposure as reportable workplace hazards, and requires employers to implement appropriate controls and staff training to manage these risks. It's crucial to give all personnel complete instructions on using and maintaining the dishwasher to prevent these problems. This must include instructions on using detergents, loading dishes, and adhering to safety regulations. In addition, making employees operate the machine appropriately and efficiently can be achieved with regular training and reminders.

5. Overloading or Underloading the Dishwasher

Overloading or underloading the dishwasher can lead to dishes not coming out clean and damaging the dishwasher. Overloading the dishwasher:
  • When the dishwasher is too full, the dishes may not be adequately cleaned because the water and detergent cannot circulate and reach all surfaces.
  • When the dishwasher is too full, the dishes may not be loaded correctly, which can cause them to bump against each other and scratch the surface.
Underloading the dishwasher:
  • When the dishwasher is not complete enough, the dishes may not be adequately cleaned because the water and detergent cannot circulate and reach all surfaces.
  • When the dishwasher is not complete enough, the dishwasher will not run efficiently and, therefore, will not be cost-effective.
To avoid these issues, it is vital to load the dishwasher correctly, ensuring that the dishes are not too tightly packed and that there is enough space for water and detergent to circulate. It is also recommended to avoid overloading the dishwasher so that the dishes have enough room to move around and be cleaned properly.

6. Not Checking for Blockages in the Spray Arms or Filters

Checking for blockages in the spray arms or filters of a dishwasher can lead to dirty dishes, reduced dishwasher performance and damage to the dishwasher.

Blockages in the Spray Arms:

  • Food debris and hard water buildup can clog the spray arms, preventing them from rotating and distributing water and detergent effectively.
  • When the spray arms are clogged, dishes in the upper and lower racks may need to be appropriately cleaned.

Blockages in the Filters:

  • Food debris and hard water buildup can clog the filters, reducing the dishwasher's performance and causing dirty dishes
  • Clogged filters can also cause the dishwasher to leak or malfunction.
To avoid these issues, check the spray arms and filters regularly and clean them as needed. To clean the spray arms and filters, you can use a brush or a toothpick to remove debris and run the dishwasher through a wash cycle with a special cleaner specifically designed for dishwashers.

7. Ignoring Maintenance Instructions from the Manufacturer

Ignoring maintenance instructions from the manufacturer of a commercial kitchen equipment dishwasher can lead to reduced performance of the dishwasher, dirty dishes, and can also damage the dishwasher. Manufacturer instructions for maintenance typically include information on the following:
  • Cleaning and maintaining the dishwasher's filters and spray arms
  • Correctly loading the dishwasher
  • Using the appropriate detergent and rinse aid
  • How often to run the dishwasher's self-cleaning cycle
  • When to replace parts, such as the inlet or outlet hose.
It is essential to consult the manufacturer's instructions and follow them accordingly. Many manufacturers also provide a troubleshooting guide to help you identify and fix common problems. In addition, following the manufacturer's maintenance instructions ensures that your dishwasher runs efficiently and that your dishes come out clean.

Conclusion: Keep Your Dishwasher Running Efficiently

The easiest way to keep your dishwasher running is to follow the manufacturer's maintenance instructions and regularly check for blockages in the spray arms or filters.
