Abstract
A one time high fill pressure switch providing energy savings operation for use in a commercial or consumer appliance such as a clothes washing machine is provided. The one time high fill pressure switch provides multiple water level settings that may be selected by a user, including a maximum fill energy savings setting. Operation in the maximum fill energy savings setting allows a maximum fill level upon the first fill cycle of the programmed washing cycle. In subsequent fill cycles during the washing cycle, the one time high fill pressure switch limits the water level to a setting below the initial fill level setting. This operation is provided through the use of a hook feature on the pressure switch program cam that traps a reset spring support and is controlled by a cam follower in the pressure switch.
