Abstract
Embodiments of the present invention relate to methods and systems for detecting and removing a clogging condition of a filter in a dishwasher. According to one embodiment, the method includes determining a normal water level or a normal rate of water level change for a wash cycle of the dishwasher and monitoring a water level or a rate of water level change during execution of the wash cycle. The method further includes detecting the clogging condition of the filter by detecting a deviation thereof. A current position of the wash cycle being executed may then be determined. The method further includes executing a remedial operation to facilitate removal of the clogging condition and determining if the clogging condition has been removed. Finally, the method includes resuming operation of the dishwasher at a wash cycle position based on the current position if the clogging condition has been removed.
