MACCHINA LAVABIANCHERIA CON FILTRO CONTROLLATO IN MODO INNOVATIVO

摘要

The invention relates to an innovative-type monitoring arrangement for the filter of a washing machine so as to ensure that the user is warned of the opportunity of cleaning the filter only when an actual need for this arises. The solution uses functional elements that are normally used in washing machines, such as an analogue pressure switch (13) and an electronic control circuit (14). The parameter that is considered in this connection is the variation of the pressure before and after the priming of the drain pump (12) of the machine.
