This had not been used for a couple of years. It fills with water, which appears to circulate through the water softener, and then the drain pump runs. Nothing further happens. The wash pump motor turns okay with a screwdriver in the slot in the end of the shaft. A multimeter on the connector in the lead to the motor does not show any voltage. Any suggestions as to why the motor is not getting power. I do not have a circuit diagram or anything that tells me how the power gets to the motor or if there is asensor or something that has to operate first?
