Daily Procedures for Commercial Dishwasher Cleaning
Daily cleaning procedures are essential to keep a commercial dishwasher properly functioning and clean. Neglecting these procedures can result in severe consequences such as foul odors, bacterial growth, limescale buildup, clogged drains, and blocked lines. By following a few simple steps, you can ensure that your commercial dishwasher operates efficiently and maintains optimal cleanliness.
Step 1: Draining and Cleaning the Water Tank After Each Shift
The first key daily cleaning procedure is to drain and clean the water tank after each shift. This prevents food debris and residue from building up, which can lead to foul odors and bacterial growth. To do this, ensure that the dishwasher is empty and then remove the wash and rinse arms. Use a soft brush or cloth to clean the arms thoroughly, removing any food particles or debris. Next, drain the water tank and wipe it clean with a sanitizing solution. By performing this step, you’ll ensure that your dishwasher is ready for the next shift.
Step 2: Cleaning the Wash Arms, Rinse Arms, and Pump Screen
The second daily cleaning procedure involves cleaning the wash arms, rinse arms, and pump screen. Over time, these components can become clogged with food particles and other debris, leading to decreased water pressure and inefficient cleaning. Start by removing the arms and soaking them in warm, soapy water to remove any buildup. Use a soft brush or toothbrush to clean the small holes and crevices thoroughly. Additionally, check the pump screen for any blockages and clean it if necessary. Taking the time to clean these components will ensure that your dishwasher operates at its best.
Step 3: Drying Out the Commercial Dishwasher at the End of the Day
At the end of each day, it’s crucial to dry out the commercial dishwasher to prevent the growth of bacteria and eliminate any remaining moisture. Simply prop open the dishwasher door and allow it to air dry overnight. This will ensure that any lingering moisture evaporates, reducing the risk of bacterial growth and foul odors. By incorporating this step into your daily cleaning routine, you’ll maintain a clean and hygienic environment for your dishwasher.
By following these daily procedures for commercial dishwasher cleaning, you can ensure that your dishwasher operates efficiently, produces clean and sanitized dishes, and avoids common issues such as foul odors and bacterial growth. Incorporating these simple steps into your routine will help to maintain the longevity and effectiveness of your commercial dishwasher, providing you with reliable service for years to come.
Drain and Clean the Water Tank After Each Shift

Clean the Wash Arms, Rinse Arms, and Pump Screen After Each Shift
One of the essential daily cleaning procedures for maintaining a clean and efficient commercial dishwasher is to clean the wash arms, rinse arms, and pump screen after each shift. Neglecting this step can lead to decreased water pressure, resulting in poorly rinsed and washed dishes. By regularly cleaning these components, you can ensure optimal performance and prevent blockages from forming.
To clean the wash arms, start by removing them from the dishwasher. Check for any signs of debris or food particles and use a small brush or toothpick to remove any clogs. Rinse the wash arms thoroughly to ensure all residue is eliminated. Similarly, the rinse arms should be inspected and cleaned using the same process.
The pump screen is another critical component that needs regular cleaning. It helps to prevent larger debris from clogging the dishwasher’s system. To clean the pump screen, locate it and carefully remove any visible debris or buildup. Rinse the screen thoroughly to ensure it is free from any obstructions. By keeping the wash arms, rinse arms, and pump screen clean, you can maintain the effectiveness of your dishwasher and ensure spotlessly clean dishes.

Dry Out the Commercial Dishwasher at the End of the Day
Properly drying out the commercial dishwasher at the end of the day is a crucial step in maintaining its cleanliness and preventing the growth of bacteria. Moisture inside the dishwasher creates an ideal environment for bacterial growth, which can lead to cross-contamination of water and poorly cleaned dishes. By propping open the dishwasher door at the end of the day, we allow the inside to air dry overnight, ensuring optimal cleanliness for the next use.
When drying out the dishwasher, it’s important to remove any remaining water droplets or moisture. This can be done by using a clean, dry cloth or towel to wipe down the interior surfaces, including the walls, shelves, and racks. Pay extra attention to areas where water tends to accumulate, such as the bottom of the dishwasher and around the drain. Ensuring that these areas are completely dry helps prevent the growth of mold and bacteria.
In addition to air drying and wiping down the interior, it’s also recommended to clean the exterior of the dishwasher. This includes the control panel, buttons, and door handle. A mild detergent and a soft cloth can be used to gently clean these surfaces. By keeping the exterior clean, we maintain a hygienic appearance and prevent the transfer of dirt and bacteria.

How to Descale a Dishwasher to Remove Limescale Buildup
Regular descaling is crucial for maintaining the longevity and effectiveness of a commercial dishwasher, especially when it comes to tackling limescale buildup. Limescale deposits are a common issue, particularly in areas with hard water. Not only can limescale affect the efficiency of the dishwasher, but it can also lead to decreased performance or even breakdown.
To remove limescale buildup, follow these steps:
- Fill the dishwasher with water. Make sure to check the manufacturer’s recommended fill level.
- Add a descaling solution to the water. There are various commercial descaling products available on the market. Follow the instructions on the product packaging for the correct dosage.
- Run a cleaning cycle. Start the dishwasher and let it run through a complete cycle, including the wash, rinse, and dry phases. This allows the descaling solution to circulate and dissolve the limescale deposits.
- Drain and refill the dishwasher. Once the cleaning cycle is complete, drain the dishwasher and refill it with fresh water. Run an additional cycle to rinse away any remaining descaling solution residue.
By regularly descaling your dishwasher, you can ensure that it operates at its best, providing sparkling clean dishes and reliable performance. This simple maintenance task can save you from costly repairs and extend the lifespan of your commercial dishwasher.
