It's important to clean a water dispenser so that the water stays safe and free of contaminants. Here's how to clean a water dispenser in general: Turn off the dispenser and unplug it. Before you clean the dispenser, you should turn it off and unplug it to avoid any electrical dangers. Empty the tank. Pour any water left in the dispenser into another container or let it drain out. Take the parts off and clean them. Take the water guard, drip tray, and any other parts that come off from the dispenser. Use warm soapy water and a soft cloth or sponge to clean each piece independently. Rinse them well, and then let them dry all the way. Clean the inside of the dispenser. To clean the inside of the dispenser, use a light cleaning solution or a mixture of vinegar and water. Use a clean cloth or sponge and the cleaning solution to wipe down the inside of the dispenser. Make sure to pay extra attention to parts that come in touch with water, like the water reservoir and the nozzle that dispenses the water. Use clean water to wash it well. Replace the parts. Once the inside and parts are clean and dry, put back the water guard, drip tray, and any other parts you took out. Fill and flush the dispenser. Fill the dispenser with clean water and let it run through the system a few times to get rid of any cleaning solution or vinegar that might still be in there. Throw away the water that was used to flush the toilet and fill the spigot with new drinking water. Once the cleaning is done, plug the dispenser back in and turn it on. It can now be used. The water dispenser should be cleaned at least once every six months, or more often if it is used a lot or if the water seems to be of poor quality. Follow the manufacturer's cleaning and maintenance guidelines at all times to make sure the dispenser is cleaned properly and safely.
