Abstract
A water inlet control system for an automatic dishwater comprising a water inlet valve (6) controleld by a program unit (7) for opening during a charging phase, in the course of which a circulation pump (9) is also operated. A transducer (13) generates an output signal proportional to the outlet pressure of the pump. The output signal of the transducer is applied to control means (16) adapted to respond to variations of the output signal for causing the valve (6) to close when the amplitude of these variations decreases below a predetermined value.
