The DeLonghi EC155 Espresso Machine is a pump espresso maker designed for consumer use in-home. Both ground coffee and pod coffee can be used in the machine. As you use the machine, it needs to be cleaned regularly. DeLonghi recommends cleaning the filter every 200 espressos, the boiler every 300 coffees and descaling every 200 coffees. Using a commercially available product designed for espresso machines is recommended by the manufacturer for descaling the unit.
Cleaning the Filter
Take the filter out of the filter holder.
Unscrew the filter cap to remove it, then push out the filter from the cap end and remove the gasket.
Clean the inside of the holder with warm soapy water and a dishcloth. Clean the filter cap, gaskets, filter and filter screen with hot, soapy water and a scrub brush. For clogs in the filter screen, use a toothpick or pin to clean.
Rinse when done and allow to dry.
Cleaning the Boiler
Unplug the unit from the power outlet once it is cool.
Locate the screw under the boiler and remove it using a screwdriver. Remove the boiler filter.
Use hot water and a scrub brush to clean the boiler filter. For clogs in the filter screen, use a toothpick or pin to clean.
Rinse when done and allow to dry
