Abstract: In un procedimento per azionare un elettrodomestico comandato a programma, in particolare una lavastoviglie, con un attacco per l'acqua calda e per l'acqua fredda, con un sistema di riscaldamento proprio dell'apparecchio e con un interruttore per il programma o simili per la selezione di diversi programmi di lavaggio e risciacquo, che comprendono almeno le fasi di programma lavaggio e sciacquo con acqua calda, il comando a programma dell'apparecchio viene completato con una variante selezionabile del programma mediante la quale il riscaldamento proprio dell'apparecchio non viene inserito in almeno un programma di lavaggio da eseguire con acqua calda. Per questo è possibile configurare il funzionamento dell'elettrodomestico con circolazione d'acqua in modo da consentire un maggior risparmio d'energia. Così si può per esempio abbassare l'assorbimento di potenza dell'apparecchio per una fase di lavaggio a meno di 300W, per cui si riduce di molto il consumo d'energia. Inoltre l'utente dell'apparecchio, nel caso di un elevato carico della rete, può decidere da sè se effettuare una fase di lavaggio a rispamio di energia senza o con riscaldamento.
