Abstract

The dishwashing machine includes baskets (12) to hold the crockery to be washed within the washing chamber (10). Underneath each basket is a rotating water spray arm (14). This has a number of jets (16) along its length and a ferromagnetic element (18) at one end. A detector (20) comprising a magnetic coil is positioned in the wall of the machine to detect the rotation of the spray arm. The detector provides pulses to a threshold comparator circuit (22). This compares the frequency of rotation of the rotor with the normal frequency, and if the actual frequency falls too low, then the warning light (24) is turned on. A further device (26) interrupts the machine supply to stop the washing cycle. If for example, a plate impedes the rotation of the spray arm, this is detected before the cycle is completed, and so an unsatisfactory wash is avoided.
