Scale buildup can be reduced by using filtered water and a filter inside the tank. Regularly descaling your machine is also advisable to ensure it continues to operate at it's best.
Automatic machines generally have a warning message reminding you when your machine is due to be descaled. To descale your machine is just a matter of putting descaling solution in the tank and following
