A fluid flow system for a laundry appliance, the fluid flow system comprising: a blower configured to deliver process air along an airflow path; a heat exchanger for dehumidifying the process air and removing condensate therefrom; a drain channel configured to receive the condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel; a sump configured to collect fluid from the drain channel, wherein the fluid at least partially includes condensate; a sump cover that includes a pump seat, a fluid outlet that are integrally formed in the sump cover; a pump configured to direct fluid from the sump and to the fluid outlet; and a fluid level sensor (460, 720) configured to detect at least a minimum capacity and a maximum capacity of the fluid in the sump; wherein: when the fluid is below the minimum capacity, the pump defines an idle state; when the fluid is above the minimum capacity, the pump defines an active state; and when the fluid exceeds the maximum capacity, the pump directs a flow of fluid to the fluid outlet of the sump cover; wherein the pump is selectively operable to direct the fluid from the sump and through the fluid outlet to a fluid diverter valve, wherein the fluid diverter valve is configured to selectively and alternatively direct the fluid to a removable bottle and the spray nozzle; wherein the fluid level sensor (460, 720) is coupled to a control configured to operate the pump; characterized in that the pump is configured to selectively operate according to an override that is independent of the fluid level sensor; wherein: the override activates the pump when the fluid level is below the minimum capacity at the completion of a drying cycle; and the pump is deactivated when the fluid in the sump reaches the maximum capacity and the fluid in the removable bottle reaches a predetermined limit. a blower configured to deliver process air along an airflow path; a heat exchanger for dehumidifying the process air and removing condensate therefrom; a drain channel configured to receive the condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel; a sump configured to collect fluid from the drain channel, wherein the fluid at least partially includes condensate; a sump cover that includes a pump seat, a fluid outlet that are integrally formed in the sump cover; a pump configured to direct fluid from the sump and to the fluid outlet; and a fluid level sensor (460, 720) configured to detect at least a minimum capacity and a maximum capacity of the fluid in the sump; wherein: when the fluid is below the minimum capacity, the pump defines an idle state; when the fluid is above the minimum capacity, the pump defines an active state; and when the fluid exceeds the maximum capacity, the pump directs a flow of fluid to the fluid outlet of the sump cover; wherein the pump is selectively operable to direct the fluid from the sump and through the fluid outlet to a fluid diverter valve, wherein the fluid diverter valve is configured to selectively and alternatively direct the fluid to a removable bottle and the spray nozzle; wherein the fluid level sensor (460, 720) is coupled to a control configured to operate the pump; characterized in that the pump is configured to selectively operate according to an override that is independent of the fluid level sensor; wherein: the override activates the pump when the fluid level is below the minimum capacity at the completion of a drying cycle; and the pump is deactivated when the fluid in the sump reaches the maximum capacity and the fluid in the removable bottle reaches a predetermined limit. when the fluid is below the minimum capacity, the pump defines an idle state; when the fluid is above the minimum capacity, the pump defines an active state; and when the fluid exceeds the maximum capacity, the pump directs a flow of fluid to the fluid outlet of the sump cover; the override activates the pump when the fluid level is below the minimum capacity at the completion of a drying cycle; and the pump is deactivated when the fluid in the sump reaches the maximum capacity and the fluid in the removable bottle reaches a predetermined limit.
