Abstract

A method of operating a laundry treating appliance with a combination washer/dryer having a cabinet defining an interior, a tub located within the interior, and a rotatable drum located within the tub interior and defining a treating chamber, and an air recirculation conduit, the method comprising supplying water to the treating chamber, rotating the drum, and draining the water from the laundry treating appliance.

First claim

What is claimed is:

1. A laundry treating appliance for performing a cycle of operation on an article, the laundry treating appliance comprising: a tub; a drum rotatably mounted within the tub; an air conduit having a port fluidly connected to the tub; a lint filter fluidly coupled to the port; and a controller configured to: determine when the previous cycle of operation was a drying cycle of operation, and upon determining the previous cycle of operation was a drying cycle of operation; determine whether a single dose dispenser is selected for the wash cycle; and wherein upon determining the single dose dispenser is selected for the wash cycle, implement: supplying, to the tub, a charge of water through a water supply configured to bypass the single dose dispenser, the charge of water sufficient to at least partially immerse the drum while not immersing the lint filter; and rotating the drum for a predetermined period of time in order to remove lint from the lint filter.

2. The laundry treating appliance of claim 1 , wherein the laundry treating appliance is a combination washer/dryer laundry treating appliance.

3. The laundry treating appliance of claim 1 , wherein the controller is further configured to determine whether a wash cycle of operation has been user-selected prior to determining when the previous cycle of operation was a drying cycle of operation.

4. The laundry treating appliance of claim 1 , wherein the controller is further configured to determine whether a treating chemistry is in the single dose dispenser.

5. The laundry treating appliance of claim 4 , wherein the controller is further configured such that determining whether a single dose dispenser is selected for the wash cycle comprises one of: a manual selection by a user via selection of a cycle requiring manual addition of treatment chemistry to the single dose dispenser, manual selection of the single dose dispenser by a user from a user interface, or by automatic selection upon sensing the presence of treating chemistry on the single dose dispenser.

6. The laundry treating appliance of claim 5 , further comprising a sensor configured to sense the presence of treating chemistry in the single dose dispenser.

7. The laundry treating appliance of claim 6 , wherein the sensor is communicably coupled with the controller.

8. The laundry treating appliance of claim 1 , further comprising a bulk dispenser.

9. The laundry treating appliance of claim 1 , wherein the controller is further configured to determine when the immediately preceding previous cycle of operation was a drying cycle of operation.

10. The laundry treating appliance of claim 1 , wherein the controller is further configured to operably proceed with a wash cycle of operation when the controller determines the single dose dispenser is not selected for the wash cycle.

11. The laundry treating appliance of claim 1 , wherein the controller is further configured to automatically implement the supplying the charge of water and the rotating the drum in response to determining the single dose dispenser is selected for a wash cycle and the laundry treating appliance comprises the water supply.

12. The laundry treating appliance of claim 1 , wherein the controller is further configured to determine whether a user selects a lint clean out routine prior to the controller determining whether the previous cycle of operation was a drying cycle of operation, and upon determining the user selected the lint clean out routine, proceeding to determine whether the previous cycle of operation was a drying cycle of operation.

13. The laundry treating appliance of claim 12 , wherein the controller is further configured to determine when the immediately preceding previous cycle of operation was a drying cycle of operation.
