  • Pause testing circuit for dishwasher controller
    Patent number: 5608769
    Abstract: A test circuit determines state of an electrical element supplied with alternating current and measures the duration of that state. The test circuit is connected to the element so that current flows to the test circuit when the element is in the state being measured. The test circuit rectifies the alternating current to periodic pulses, which are counted to determine the duration of the current and, thus, the state. The circuit is particularly useful for testing operation of a dishwasher pump motor that is interrupted periodically. The test circuit is connected to auxiliary contacts that open and close in correspondence with the operation of the pump motor.
