Abstract
A monitoring arrangement for the filter of a washing machine is disclosed wherein the user is warned of the clogged filter when an actual clogging condition occurs. Control elements that are normally used in washing machines, such as an analog pressure switch (13) and an electronic control circuit (14), are utilized. The control parameter for detecting clogging is the variation of the water pressure before and after the priming of the drain pump (12) or the recirculator pump (17) of the machine.
