Ted for Model Number SHX3AR75UC/22 Hello! Our Bosch dishwasher (SHX3AR75UC/22) is not draining. I have already replaced the drain pump motor, checked the flow back flap, and cleared all drainage lines for blocks. I have noticed that when the dishwasher attempts to drain (either at the end of a cycle or when I manually raise the float to prompt a drain) the drain pump motor will make three short attempts (whirls up and spins the impellers three short times in succession) and then stops. The dishwasher will then beep and cancel the cycle. Thanks!
Answer Ted, during the three short bursts of an attempt to drain, water should be able to be heard going into the drain pipe. If not, then it would be recommended that the connection where it goes into the house drain or disposal is inspected. There could be a clog in the connection point (if a new disposal has been installed, the drain plug may not have been knocked out). The three short cycles are used by the main control to identify if there is a clog before trying to drain. Once all of the above mentioned have been inspected, the last step would be a failure in the main control board 12010638. Read More... Answered by AppliancePartsPros.com | Monday, April 20, 2020
