A:Answer1. Descaling does need to be done, but the frequency would depend upon the hardness of your tap water -- which I would HIGHLY suggest you filter before filling the reservoir. (You program the machine based upon your home's water softness so that it will let you know when it's time.) The machine comes new with a dose of the DeLonghi descaling solution which you can purchase more online for future cleanings. It must be pretty harsh/acidic because it says not to get it on your clothes. I've also seen videos of people using white vinegar, so you might check that out. 2. You shouldn't get any algae growth with filtered water. The reservoir is at the back of the machine -- but it is clear. Just keep it out of direct sunlight and you should be fine.
A:AnswerI normally use a small plastic or wood spoon or knife to scrape or loosen the grind into my collection can (great for my plants). Then I rinse the filter with water. I normally follow the manual’s recommendations for cleaning the filter when I’m done making coffee.
A:AnswerHello Robbie,
We understand that a bottomless portafilter allows you to view the beautiful extraction process, but we do not recommend using any other portafilter than the one designed for your specific unit.
Thank you!
