How often do I need to descale my Philips 2200 espresso machine?

With the AquaClean filter installed, you won't need to descale your machine for up to 5000 cups. The machine will prompt you when it's time to change the filter, and once replaced, you can enjoy another 5000 cups before descaling is required again. The actual number of cups may vary depending on your selected coffee varieties and cleaning patterns.
