Abstract

The present invention relates to a wash method in a dishwashing machine, of a type suitable for implementing at least one phase for checking the value of the pressure (12, 15, 17, 36) existing in one or more points of the hydraulic circuit of said dishwashing machine through sensor means in order to carry out subsequent actions (13, PF, 16, 18) of said method (1), which are commanded by a machine management and control system suitable for detecting and processing information. The peculiarity of the wash method consists in the fact that it comprises a special wash cycle (PF) which is capable of, when said sensor means in a pressure value check phase (12, 15, 17) provide values which are below a certain threshold suitable for ensuring a sufficient head to a wash pump of said hydraulic circuit in order to carry out an effective washing of the kitchenware, accomplishing hydraulic pressure conditions similar to those attainable in normal operating conditions, i.e. with filters (51, 52, 54) of the same hydraulic circuit free from residues or solid dirt.
