Cleaning the outer housing
The outer housing and LCD screen can be cleaned with a soft, damp cloth. Apply cleanser
to the cloth and not the LCD surface. Polish with a soft, dry cloth. Cleaning and drying with
dry paper towels or abrasive cloths and cleaners may scratch the surface.
removing Calcium Build-up
Your coffee machine may experience build-up from calcium and minerals contained in your
water. This ‘scale’ or mineral build-up will affect the machine’s performance and coffee qua-
lity. It is critical that scale build-up, so it has to be removed frequently.
If there is an excessive mineral build-up, the LCD screen will display ‘DE-SCALE’.
