The invention relates to a ware washer (40, 50) and to a method for operating a ware washer (40, 50) which is designed as a programmable machine (40) or as a conveyor ware washer (50) and which has at least one pump (11, 11-1, 11-2, 11-3, 11-4, 11-5, 11-6), at least one line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6) connected to the pump (11, 11-1, 11-2, 11-3, 11-4, 11-5, 11-6), and at least one nozzle system connected to the line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6) and having at least one nozzle (13, 13-1, 13-2, 13-3, 13-4, 13-5, 13-6, 13-7), a liquid being supplied at least intermittently to the at least one nozzle (13, 13-1, 13-2, 13-3, 13-4, 13-5, 13-6, 13-7) via the line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6). Furthermore, a sensor device (30, 30′, 30″) connected to a control device (20) is provided for detecting a profile of the hydrostatic pressure (Pi) of the liquid in the line system (12, 12-1, 12-2, 12-3, 12-4, 12-5, 12-6) and for comparing the detected pressure profile (Pi) with a predetermined pressure profile (Ps). In order to achieve the situation where potential deviations of the water circulation capacity or potential deviations of the nozzle pressure can be ascertained and automatically reacted to correspondingly in order to counteract the deviation of the water circulation capacity, according to the invention the control device (20) is designed, in the event of a deviation of the detected pressure profile (Pi) from the predetermined pressure profile (Ps), automatically either to carry out a regulating action on the operation of the ware washer (40, 50) as a function of the size and the time gradient of a difference between the predetermined pressure profile (Ps) and the detected pressure profile (Pi) or to issue a fault warning via an optical and/or acoustic interface (22) or to issue a fault warning to a remote maintenance station via a remote control interface (23). |
