Abstract

Vorgeschlagen wird eine Geschirrspülmaschine, insbesondere eine Haushaltsgeschirrspülmaschine (1), mit einer Steuereinrichtung (2) zum Durchführen eines Spülgangs für das Reinigen von Spülgut, mit einer Spülkammer (7) zur Aufnahme des Spülguts während des Spülgangs, mit einem durch die Steuereinrichtung (2) öffen- und schließbaren Zulaufventil (18) zum Einfüllen von Spülflüssigkeit (S) in die Spülkammer (7), mit einer Umwälzpumpe (22) zum Umwälzen der in der Spülkammer (7) befindlichen Spülflüssigkeit (S), deren Drehzahl (DZ) durch die Steuereinrichtung (2) variierbar ist, und mit einer Rundlaufüberwachungseinheit (25) zur Durchführung einer Rundlaufprüfung bei der Umwälzpumpe (22), wobei der Spülgang mindestens eine Füllsequenz (F) umfasst, bei der während einer Füllphase (FP) das Zulaufventil (18) geöffnet und die Umwälzpumpe (22) eingeschaltet ist, wobei für die Füllphase (FP) ein Algorithmus zum Variieren der Drehzahl (DZ) der Umwälzpumpe (22) vorgesehen ist, wobei der Algorithmus einen Variierungsschritt (VAS) zur stufenförmigen Variierung der Drehzahl (DZ) um einen Vorgabewert (VW), einen Prüfschritt (PS) zur Durchführung einer Rundlaufprüfung und einen Veränderungsschritt (VES) zur Veränderung des Vorgabewertes (VW) für eine erneute Durchführung des Variierungsschrittes (VAS) in Abhängigkeit eines Ergebnisses des Prüfschrittes (PS) umfasst.

A dishwasher is provided, in particular a domestic dishwasher (1), with a control device (2) for carrying out a rinse cycle for cleaning items to be washed, with a rinsing chamber (7) for receiving the items to be washed during the rinse cycle, with a control unit (2) openable and closable inlet valve (18) for filling rinsing liquid (S) into the rinsing chamber (7), with a circulating pump (22) for circulating the rinsing liquid (S) present in the rinsing chamber (7), the speed (DZ) of which Control device (2) is variable, and with a concentricity monitoring unit (25) for performing a concentricity test in the circulation pump (22), wherein the rinse comprises at least one filling sequence (F) in which during a filling phase (FP) the inlet valve (18) opened and the circulation pump (22) is turned on, wherein for the filling phase (FP) an algorithm for varying the speed (DZ) of the circulation pump (22) vorg the algorithm is a varying step (VAS) for stepwise variation of the speed (DZ) by a default value (VW), a check step (PS) to perform a concentricity test and a change step (VES) to change the default value (VW) for a carrying out the varying step (VAS) again as a function of a result of the test step (PS).
