(57) A device for controlling the washing of the filter (2) of a dishwasher performed by nozzles (7) fed through a cleaning duct (6) which branches out from the feed duct (5) coming from the washing pump, includes a valve suitable to interrupt the water flow upstream from said nozzles (7), said valve being mechanically activated for closing, against the strength of an elastic member, through means suitable to transmit thereto the push of the water pressure. A possible embodiment includes a gate valve (8) activated through a lever (11) and a vertical small rod (14) pushed by a flexible membrane (17) which closes an opening formed in the wall of the cleaning duct (6).
