ABSTRACT:
A dishwashing machine having a reservoir (6) communicating with the washing tank (1) through a lower aperture (7) connected to the delivery side of a drain pump (3). The reservoir (6) comprises an upper aperture (9) capable of communicating with the outside ambient through a valve (10) which is controlled by the program sequence control switch (13) of the machine so as to open during a pre-determined water discharge phase to enable the reservoir (6) to be filled by the water being let out from the tank (1); to temporarily close so as to prevent said reservoir (6) from emptying after said water discharge phase; and to finally open again so as to enable the water stored in the reservoir (6) to flow back into the washing tank (1), through the lower aperture (7) and the pump (3), to be used during said subsequent phase of the washing process.
