Purpose: Remove limescale deposits, caused by magnesium and calcium, from the internal workings of the espresso machine.
Machine identity: These instructions are provided for descaling a superautomatic single boiler espresso machine with water reservoir. Your espresso machine must have a single internal boiler that provides both water for espresso extraction and steam for steaming/frothing milk. In other words, there is a separate steam switch you must depress to get steam AND where you wait 30 or more seconds to get steam. If you have a superautomatic espresso machine with a dual boiler, these instructions will not suffice. Please check with the manufacturer or your selling dealer if you are not sure.
Requirements before you start: cold espresso machine in power off position and plugged into outlet, descaling product, mixing container/pitcher, fresh water.
- If your instruction manual has instructions for descaling, please use those instructions as the primary instructions, and please use the following as secondary instructions.
- Remove water from reservoir.
Follow instructions on descaler product to acquire proper solution ratio as most descalers require a mixture with water into a mixing container/pitcher. We sell Ascaso Coffee Washer for descaling.
