METHOD FOR DETECTING ROTATION OF A DISHWASHER SPRAY ARM

摘要

A method for detecting rotation of a dishwasher spray arm, wherein the method comprises: (a) detecting vibrations generated during operation of the dishwasher; (b) comparing the level of the detected vibrations with a predetermined threshold, and increasing a count value in dependency of whether the level of the detected vibrations exceeds the predetermined threshold; (c) comparing the count value that is obtained for a predetermined period of time with a predetermined target range; and (d) determining that there is a disturbance in the rotation of the spray arm, when the count value is outside the predetermined target range.
