Customer Questions and Answers for Dishwasher Detergent And Rinse Aid Dispenser by Bosch

Al, it would be recommended that the wires are inspected for any loose connections. As the dishwasher should be able to operate even when the rinse aid needs to be refilled, this issue could be in the door latch assembly 10028963 or in the main control 00705047. If the wire connections are good, the next step would be to test the latch for 10 Volts. If there is proper voltage, the latch has failed. If there is not proper voltage, the main control has failed.
