Abstract
According to exemplary embodiments, a dishwasher or other washing appliance includes a siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain fluid from the dishwasher or other washing appliance. The siphon break apparatus may include a body portion that may be divided by a filter into a filter chamber and a flow chamber. The filter chamber may extend perpendicularly from the flow chamber. An aperture may be defined in the filter chamber and sealed shut by a domed closure of a normally-closed umbrella valve. The domed closure may unseal from the aperture and thereby allow air to enter the filter chamber, travel through the filter and into the flow chamber so as to relieve a low pressure region and substantially prevent a siphon effect in the fluid conduit. A related method is also provided.
