A control system for controlling a fill operation of a dishwasher having a pump and a pump motor driving the pump, and the dishwasher having a valve for controlling the flow of water to the dishwasher includes a monitoring device configured to be coupled to at least one of the pump and the pump motor. The monitoring device generates an output relating to at least one of an operating current and a speed of the pump motor.

The output relates to a fill condition of the dishwasher.
