Method for automatically performing the cleaning, by detergent, of dispensing assemblies of espresso coffee makers and arrangement for carrying out the method

摘要

A method for the automatic cleaning of dispensing assemblies of espresso coffee makers involves replacing the normal filters 18 used for percolation of coffee, in the filter holders 12 of dispensing assemblies 14 with blind filters 22 and pouring a batch of detergent 28 into the blind filters 22. After this, by operating a keypad 32 of the espresso coffee maker, one enters a washing program that begins at a predetermined time, preferably selected during the hours of rest or the time when the premises are closed, arranging for a series of alternating wash cycles 44 with off cycles 46 until reaching a predetermined number of complete washing cycles. Once the number of washing cycles is complete, one can have a series of alternating rinse cycles 72 carried out with off cycles 76 until reaching a predetermined number of complete rinse cycles. After completion of the rinse cycles, the machine is ready to operate. IMAGE
