Abstract:

A system and method of operating a water supply system with one or more water consuming appliances is provided. The water supply system includes a hot water heater for supplying a flow of heated water through a supply conduit to at least one water consuming appliance. The water consuming appliance receives the flow of heated water and provides an indication of a fault condition if excessive water accumulates in the appliance, which might indicate a malfunction with a drain pump or a water supply valve. A safety shutoff valve is positioned on the supply conduit and is in operative communication with the water consuming appliance. The safety shutoff valve is configured for stopping the flow of heated water when it receives the indication of the fault condition.
