Key Takeaway
To self-clean a Primo water dispenser, first, unplug the dispenser and remove the water bottle. Mix a cleaning solution of 1 gallon of water and 1 tablespoon of unscented household bleach. Pour the solution into the water reservoir, close the dispenser’s doors, and plug it in. Press the self-clean button and let the solution fill the dispenser’s hot and cold reservoirs. After 20 minutes, empty the hot and cold reservoirs by dispensing the solution, and refill them with fresh water. Repeat the process until there is no smell of bleach, and then reattach the water bottle.

Gather the Required Materials

Keeping your Primo water dispenser clean and well-maintained is essential to ensure the quality of your drinking water. Self-cleaning the dispenser can save you time, money, and effort, and you can do it easily with just a few basic supplies and materials. Firstly, you’ll need to gather all the required materials for the cleaning process.

The materials you need might vary depending on the type and model of your Primo water dispenser. However, some common materials you’ll need include a cleaning solution, a sponge or cloth, a bucket, and a clean water source. You can use vinegar, bleach, or a specialized cleaning solution designed for Primo water dispensers. The bucket is necessary to collect the old water and clean the dispenser parts. Additionally, you will require a cleaning cloth or sponge to clean the inside and outside of the dispenser and a clean water source to rinse the parts. Without gathering these materials, you won’t be able to effectively clean your Primo water dispenser.

Turn Off and Disassemble the Primo Water Dispenser

Before you begin the self-cleaning process for your Primo water dispenser, make sure you turn off the machine and unplug it from the power source for safety purposes. Disassembling the dispenser is also an important step to take before cleaning.

To start, remove the water bottle from the dispenser and take off the drip tray. Next, unscrew the water guard and spout assembly. You can do this by turning the spout counterclockwise until it comes off. Once these parts have been disassembled, you can begin washing and disinfecting them thoroughly before reassembling them.

It’s important to follow the specific instructions for disassembling and reassembling your Primo water dispenser to ensure you don’t damage any parts and that the machine works properly after cleaning. Taking these necessary steps can help prolong the life of your water dispenser and ensure you have clean, fresh-tasting water every time you use it.

Clean the Water Dispenser Components

Once you have removed the dispenser’s exterior dirt and grime, it’s time to clean the internal components. Begin this process by detaching the regular parts of the water dispenser, including the reservoirs, taps, and drip tray. Be sure to consult your manufacturer’s manual before starting this process as the design and parts location may vary between models.

For cleaning the components, you can use household products like vinegar or a mixture of baking soda and water. Make sure to use a soft sponge or scrubber to avoid damaging the dispenser’s surface. For hard to reach areas, such as the nozzles, you can use a small brush or toothbrush. Rinse thoroughly before reassembling the components back into the dispenser. Cleaning the internal components not only maintains the dispenser’s cleanliness and hygiene but also contributes towards efficient working, and long-lasting performance.

Sanitize the Water Dispenser

Sanitizing your Primo water dispenser is an important step in the self-cleaning process. This step involves killing bacteria and germs that may be present in the dispenser. Sanitizing the dispenser involves using a bleach solution that should be thoroughly rinsed before using the dispenser again.

To sanitize the water dispenser, mix a solution of one tablespoon unscented bleach per gallon of water. Fill the water bottle partially with the solution and use it to fill the reservoir. Allow the solution to sit in the dispenser for five minutes before dispensing it through the faucets. Discard the remaining solution in the water bottle.

After sanitizing, rinse the water dispenser thoroughly with cool water. Do not use hot water as it may damage the dispenser or warp the plastic components. Once you have rinsed it thoroughly, refill it with water and allow it to run through the faucets for several minutes to remove any remaining traces of bleach solution. Now your Primo water dispenser is sanitized and ready for use.

Reassemble the Water Dispenser

After you have successfully cleaned the parts of your Primo water dispenser, it is time to reassemble them carefully. Make sure you refer to the user manual to ensure that you put all the parts together correctly. If you do not have the manual, you can visit Primo’s website and download one.

First, reattach the parts of the water dispenser that you removed. Put the water reservoir back under the taps, install the drip tray, and place the bottle on top of the dispenser. After putting everything back together, plug the water dispenser in, and turn it on. Wait for a few minutes and listen for any unusual noise coming from the machine. If you hear any noise or if the water pressure is low, make sure to check all the connections again. When the machine is working correctly and dispensing the water as it should, you can start using it again.

Test the Water Dispenser

After cleaning your Primo water dispenser, it’s important to test it out to make sure everything is working correctly. Let your dispenser run for a few minutes to eliminate any air trapped in the system. This can cause the water to sputter and spit, resulting in a poor water flow. Once the air has been expelled, fill a cup with water and ensure that it is clear and free of any impurities.

It’s also important to check the temperature of the water. Primo water dispensers come with a hot, cold, and room temperature setting. Ensure that the cold water is chilled, the hot water is hot, and the room temperature setting dispenses water at room temperature. Finally, run your hand along the outside of the dispenser to ensure that it’s not overheating. If you notice any issues during testing, refer to the Primo user manual or contact their customer service team.
