Abstract: A method of determining a position of a diverter of a fluid circulation system in a dishwasher appliance includes measuring a fluid pressure in a sump of the dishwasher appliance while pumping fluid from the sump into a wash chamber of the dishwasher appliance via a first component when the diverter is in a first position. The method also includes measuring the fluid pressure in the sump of the dishwasher appliance while pumping the fluid from the sump to a filter cleaning manifold when the diverter is in a second position. Based on the measured fluid pressure, the method determines whether the diverter is in the second position.
