Remove power from the unit, unplug the motor and check that it has continuity OR measure across it to see if it is getting 120 volts when it should.
An open winding or if it does not run when receiving voltage indicate a bad motor.
If no voltage, unplug the unit, set the timer to where it should be washing and measure from 8T to 2C (power in contacts) if closed (0 ohms) measure from 8T to 2T (Motor contacts), this also should be closed.
