In the following sections, we'll explore some of the most effective methods for descaling your commercial dishwasher based on expert advice and industry best practices.

With our step-by-step instructions and helpful tips, you'll be able to tackle limescale buildup and other common dishwasher issues with confidence, ensuring that your business runs smoothly and your customers are always satisfied.

Why Descaling is Important

Descaling a commercial dishwasher is crucial in maintaining its performance and extending its lifespan. The heating element in a dishwasher raises the temperature of the water to sanitize dishes and remove food particles. However, over time, minerals in the water can build up on the heating element, causing limescale to form. This buildup can decrease the machine's performance and make it difficult to achieve high temperatures for cleaning.

Regular descaling is necessary to prevent limescale buildup and maintain the dishwasher's efficiency. If left unchecked, limescale can cause permanent damage to the machine, leading to costly repairs or even replacement. Additionally, limescale buildup can cause mineral deposits to form on dishes, leaving a white film that is difficult to remove.

By descaling the dishwasher regularly, employees can ensure that the machine is working at its best and producing clean, sanitized dishes. It also helps to prevent breakdowns and extends the lifespan of the dishwasher, saving the business money in the long run.

Types of Commercial Dishwashers

Different types of commercial dishwashers are available in the market, each designed for specific needs and requirements. Here are two common types:

Conveyor Dishwashers

Conveyor dishwashers are ideal for large-scale dishwashing needs in busy restaurants and hotels. These machines use a conveyor belt to move dishes through the wash cycle, making them efficient and time-saving. They come in different sizes and capacities, making them suitable for various business needs.

Conveyor dishwashers have a pre-wash zone, wash zone, and rinse zone, and they use high-temperature water to clean and sanitize the dishes. They also come with detergent and rinse aid dispensers, making adding cleaning solutions to the machine easy.

One of the downsides of conveyor dishwashers is that they require a lot of space and are expensive to install. They also consume a lot of water and energy, making them less eco-friendly than other types of dishwashers.

Door-Type Dishwashers

Door-type dishwashers, also known as under-counter dishwashers, are compact and space-saving machines designed for smaller restaurants and cafes. They are installed under the counter, making them easy to access and use.

Door-type dishwashers use a pump to add detergent and rinse aid to the wash cycle, and they have a built-in sanitizer to ensure that dishes are properly sanitized. They also have a deliming cycle to remove mineral buildup from hard water.

One of the benefits of door-type dishwashers is that they are energy-efficient and use less water than conveyor dishwashers. They are also less expensive to install and maintain, making them a popular choice for small businesses.

Overall, choosing the right type of commercial dishwasher depends on the size and needs of the business. Conveyor dishwashers are ideal for large-scale operations, while door-type dishwashers are suitable for smaller businesses. Both types of dishwashers are efficient and effective in cleaning and sanitizing dishes, making them essential equipment for any commercial kitchen.

How to Descale a Conveyor Dishwasher

If you are running a commercial kitchen, you know that a conveyor dishwasher is crucial. However, mineral buildup can occur over time, leading to decreased efficiency and performance. Fortunately, descaling your conveyor dishwasher is a simple process that can be completed in just a few steps.

Step 1: Turn off the Dishwasher

Before descaling your conveyor dishwasher, ensure it is turned off and unplugged. This will ensure your safety and prevent any damage to the machine.

Step 2: Remove the Spray Arms

Next, remove the spray arms from the machine. This will allow you to access the interior and ensure that the descaling solution reaches all areas of the machine. Keep track of any screws or clips you remove so that you can easily reassemble the machine later.

Step 3: Add Descaling Solution

Once the spray arms are removed, add the descaling solution to the machine. The amount of solution you need will vary depending on the size of your machine, so consult the manufacturer's instructions for guidance. Allow the solution to sit in the machine for the recommended amount of time, typically 30-60 minutes.

Step 4: Run the Dishwasher

After the descaling solution has had time to work, run the machine through a full cycle. This will ensure that the solution reaches all areas of the machine and removes any mineral buildup. Make sure to follow the manufacturer's instructions for running the machine.

Step 5: Rinse the Dishwasher

Finally, rinse the machine thoroughly with clean water to remove any remaining descaling solution. Make sure to reattach the spray arms and any other parts you removed during the process.

By following these simple steps, you can keep your conveyor dishwasher running smoothly and efficiently. Remember to descale your machine regularly to prevent mineral buildup and ensure optimal performance.

How to Descale a Door-Type Dishwasher

Descaling a door-type dishwasher is an essential maintenance task to keep the machine running efficiently. Over time, mineral buildup can cause clogs and decrease the effectiveness of the dishwasher. Here are the steps to descale a door-type dishwasher:

Step 1: Turn off the dishwasher

Before starting the descaling process, make sure that the dishwasher is turned off and unplugged. This will ensure that there is no risk of electrical shock or damage to the machine.

Step 2: Remove the spray arms and filters

Remove the spray arms and filters from the dishwasher. Soak them in warm water and dish soap to remove any debris or buildup. Use a soft-bristled brush to scrub away any stubborn buildup.

Step 3: Add descaling solution

Prepare a solution of descaling solution and water according to the manufacturer's instructions. Pour the solution into the bottom of the dishwasher.

Step 4: Run the dishwasher

Close the dishwasher door and run a normal cycle. The descaling solution will circulate throughout the dishwasher and break down any mineral buildup.

Step 5: Rinse the dishwasher

Once the cycle is complete, open the dishwasher door and allow the machine to cool down. Rinse the interior of the dishwasher with clean water to remove any remaining descaling solution.

Regularly descaling a door-type dishwasher will help keep it running efficiently and extend its lifespan. Follow these steps to keep your dishwasher in top condition.

Preventing Scale Buildup

Preventing scale buildup is essential to keep your commercial dishwasher in good condition and ensure it operates at optimal levels. Here are some tips to prevent scale buildup:

Use the Right Detergent

Using the right detergent is crucial to prevent scale buildup in your commercial dishwasher. Make sure to use a detergent specifically designed for commercial dishwashers. Avoid using regular dish soap as it can cause excessive sudsing and lead to scale buildup.

Check the Water Hardness

Water hardness is a measure of the amount of minerals, such as calcium and magnesium, present in the water. Hard water can cause scale buildup in your dishwasher and reduce its efficiency. You can use a water hardness test kit to determine the hardness of your water. If the water hardness is high, you may need to install a water softener to reduce the mineral content of the water.

Clean the Dishwasher Regularly

Regular cleaning of your commercial dishwasher is essential to prevent scale buildup. Make sure to clean the dishwasher at least once a week with a commercial detergent. It is also important to remove and clean the filter every month to prevent any food or grease buildup. Additionally, you should descale your dishwasher using a premium limescale remover for maintenance to keep it working at its best.

Conclusion

Descaling a commercial dishwasher is essential to maintain its performance and prolong its lifespan. Descaling the dishwasher at least once a year is recommended to ensure it is functioning optimally. Neglecting to descale the dishwasher can lead to mineral buildup, which can cause damage to the machine and result in poor cleaning results.

To descale a commercial dishwasher, one should start by thoroughly cleaning the dishwasher, and removing any debris and food particles. Next, remove the screens, filters, or baskets and clean them with a brush and warm water. Ensuring that the filters, baskets, and screens are not clogged with food particles is important.

After cleaning the components, one should re-install the parts and run a descaling solution through the dishwasher. Following the manufacturer's instructions when using a descaling solution is important, as different solutions may have different instructions. Once the solution has run through the dishwasher, it should be drained and rinsed thoroughly with clean water.

Regular maintenance of the dishwasher, including cleaning and descaling, can help prevent breakdowns and ensure that the machine functions at its best. It is also important to check the dishwasher filter regularly and clean it as needed, as a clogged filter can impact the performance of the dishwasher.
