A dishwasher having a speed-controlled induction motor coupled to a pump to drive the pump during dishwasher operation. A motor controller is connected to the induction motor to control the speed of operation of the induction motor. A dishwasher controller is connected to the motor controller for sending signals to, and receiving signals from, the motor controller during operation to control the motor speed. The flow rate of water through the pump discharge to a spray arm is controlled based on the phase of the wash cycle and the condition of the filter that blocks food debris from entering the sump. The motor speed is decreased to decrease the pump flow rate when the flow rate through the filter decreases in an early phase of the wash cycle. The motor speed is increased to increase the pump flow rate during later phases of the wash cycle. In steady state operation, the flow rate through the filter is matched to the flow rate through the pump discharge.
