Although the water tank doesn’t require everyday cleaning, all the other replaceable parts do. If you want to maximize the lifespan of the coffee maker, it is vital to clean it after every use. Since the tank is detachable, remove it and wash it with lukewarm water and soap when needed. Apart from the regular cleaning, you should deep-clean the unit once a month. Fill the tank with water and vinegar in a 1:1 ratio. Activate the brewing process, but only brew halfway, and then stop the machine. Allow it to rest for half an hour and complete the brewing process. Remove the content of the reservoir and rinse it thoroughly with water. Return the component to the machine, and start another brewing process with clean water to rinse the appliance. It is best to use paper filters for each of these two processes. Deep cleaning will make your water reservoir clean, but also will prolong the lifespan of the device.
