How often should I service my Espresso Machine & Coffee Grinder?

Well, ultimately it depends on a series of factors such as amount of usage, how well taken care of, how often the machine is cleaned and maintained by the users and quality of water entering the machine! (The more calcium reaches into your coffee machine the more calcium scale;limescale will form and cause a series of problems).

CALCIUM SCALE also known as Limescale

Calcium scale is the main cause of problems in coffee machines. It is a hard deposit which forms inside your coffee machine tubes, valves and boiler when there is a high concentration of calcium in the water passing through your machine. By servicing and clearing away any built up calcium scale, this will prevent your boiler from overworking and your boiler tubes to be in good condition. Rust, breakage, leaky and failure of overworked parts (Rubber Gasket, Pumps, Shower screen, Cams & Screws) are the main reasons why espresso machines deteriorate over time and servicing would be essential to ensuring your machine stays healthy, produces perfect extraction of espresso and for repair costs to be kept LOW in the long run! Moving parts should always be lubricated with high quality food grade grease lubricant to avoid wear and tear and for the machine to perform optimally.
