ABSTRACT:
A sensor is provided for sensing operational characteristics of a dishwasher. The sensor includes a microphone mounted within the door of the dishwasher. The microphone is connected through electrical circuitry to a microprocessor mounted within the door. The microphone is adapted to generate a signal in response to impingement of water from the rotating wash arms upon the inside of the door. The signal is sent to the microprocessor, which converts the signal into information regarding the rotational velocity of the wash arm. This information is processed to control the operational parameters of the dishwasher.
