Abstract
A control system for monitoring the filling of a washing appliance with liquid. The control system energizes a fault indicator when a no-fill and/or an overfill condition occurs. Specifically, when a no-fill condition occurs at a time when the washing appliance should have a predetermined liquid level therein, the control system energizes a fault indicator and suspends operation so that damage to the washing appliance is prevented and/or minimized. When an overfill condition (i.e., a liquid level above a predetermined level) occurs the control system energizes a fault indicator and suspends operation to prevent and/or minimize damage to the washing appliance and/or the surrounding environment.

11. A control system for a washing appliance comprising:
-
a liquid fill device operable to selectively allow a liquid to flow into a washing appliance;
a fault indicator operable to signal occurrence of a no-fill condition when energized;
a level sensor responsive to a level of said liquid in said washing appliance;
