More Information
Summary:A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.
