Abstract
Dishwashing machine including a valve (7) that is open during a water inlet phase and a circulation pump (11) that is energized during the water inlet phase. A control arrangement is driven by a signal (V) that is proportional to the outlet pressure of the circulation pump so as to close the inlet valve (7) when signal variations decrease below a pre-determined value. The circulation pump (11) is driven by a single-phase asynchronous motor (14) with a phase-shift capacitor (15) from which the signal (V) is derived. A further signal (U) can be derived from the capacitor (15) to drive the control arrangement so as to determine the correct de-energization of a discharge pump (18).
