Abstract

In one aspect, a dishwasher comprising a control mechanism coupled to a sensor for generating an output representative of an amount of soil in the dishwasher water is described. The dishwasher comprises a tub, at least one filter for filtering water in the tub, and a fluid circulation assembly for circulating water in the tub. The control mechanism is configured to determine whether corrective action is needed to unclog the filter based on a signal output by the sensor.
