Abstract

A system for operating and programming a laundry appliance includes a menu system giving a user extreme flexibility in operating the appliance. Through a series of menu screens, the user is presented with a variety of available options. Additionally, the laundry appliance of the invention gives the user access to databases, preferably already programmed into memory of the appliance, such as general tips for laundering and simple troubleshooting. Finally, the user has the ability to program the menu system.

providing a touch-screen control panel;

receiving an initial programming input for the appliance from a user through the control panel, said initial programming input relating to a selected one of the plurality of laundry programs;

prompting the user for additional programming input through the control panel; and

performing a laundry operation in the laundry appliance, utilizing the operating instruction and each of the initial and additional programming inputs.

2. The method according to claim 1, further comprising:

selecting a different laundry program stored in a memory; and

performing the laundry operation based on operating instructions from the different laundry program.

3. The method according to claim 1, further comprising:

a controller for establishing a laundry operation based on the selected programming options.

14. The method of claim 13, wherein the step of simultaneously presenting a plurality of laundry options to a user includes displaying a check-box in proximity to each of the plurality of laundry options in the display device.

15. The method of claim 14, further comprising:

placing a symbol in the check-box in proximity to each of the selected laundry options selected by the user.

13. In a laundry appliance having a CPU, a memory having stored therein a laundry sequence and at least one laundry operation, and a dynamic display device, showing a screen, a method of controlling the laundry appliance comprising:

simultaneously presenting a plurality of laundry options to a user through a single menu display; and

selecting a plurality of the laundry options without changing the plurality of laundry options displayed on the single menu display.
