Cleaning your Bezzera BZ10
Keeping your espresso machine clean is one of the most important things as a barista. If you have the most expensive machine and coffee in the world, but your machine is dirty you will never get a good tasting espresso out of it.
Keeping the brewing group clean is the first thing, this can be done by backflushing the group head. You do this with a blindfilter and Puly caff cleaning detergent. This removes the coffee residues on the inside of the group and the 3 way solenoid valve.
If you make cappucino’s and Latte’s you need to clean the steam tube. This can be done with the help of a milk pitcher and Brooks milk cleaner. After soaking the steam tube in the solution the old milk residues can be removed pretty easily.
Descaling a BZ10 espresso machine
Descaling your espresso machine can never be prevented, but it can be postponed with a proper water filter in the water tank of your BZ10.
The consumer can descale a single boiler heat exchanger. Descaling does not need to be done regularly because it is not the main cleaning technique for prosumer model machines. Descaling can be carried out every three to four months, or more frequently if the machine exhibits flow problems. The necessity for more regular descaleing may arise if the machine is subjected to harsh water conditions or heavy operation.
