Abstract

This invention relates to a dishwasher (1) where the signals generated by the speed controller (7) of the variable speed motor (5) that drives the circulation pump (4) are observed by the control card (8) and the motor (5) input voltage is adjusted and where elements that adversely affect washing performance such as filter clogging, foaming, increase in viscocity or inappropriate amount of water in washing chamber (3) are detected. Pulse width modulation signals (PWM" constitute the output signals of the speed controller (7).
