Abstract (en)

A method of operating a dishwasher comprises providing a dishwasher having at least one main spray device, at least one auxiliary spray device and a motor-driven circulation pump which is selectively placed in fluid connection with said spray devices, executing a washing cycle (CL) in which the motor-driven pump feeds all the spray devices. The washing cycle (CL) comprises a first operating period (PL1) and a second operating period (PL2) of the motor-driven pump, in said first operating period (PL1) the motor-driven pump being operated to rotate at a first rpm value (R1) and a second rpm value (R2), with a pulsed operation alternating the first rpm value (R1) and the second rpm value (R2), in said second operating period (PL2) the motor-driven pump being operated to constantly rotate at a third rpm value (R3) higher than the first rpm value (R1) and lower than the second rpm value (R2).
