Abstract
According to example embodiments, a dishwasher may include a siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain a fluid from the dishwasher. The siphon break apparatus may include a first check valve in fluid communication with the fluid conduit and exposed to a pressure therein and a second check valve in fluid communication with the first check valve. The first and second check valves may be configured to be substantially closed when pressure in the fluid conduit increases as a result of fluid being pumped through the fluid conduit and substantially open when pressure in the fluid conduit decreases as a result of the fluid no longer being pumped through the fluid conduit. Thereby the siphon effect may be substantially prevented.
