ABSTRACT:
A screening arrangement is provided for a dishwasher having a tub portion defining a sump about a lower end thereof. The dishwasher further includes a heating element disposed proximate to the lower end of the tub portion and defining laterally-opposed inner and outer peripheries. A screen element is arranged adjacent the sump and is configured to screen a dishwashing fluid entering the sump from the tub portion. The screen element extends laterally inward of the inner periphery of the heating element and laterally outward of the outer periphery of the heating element. The screen element is also configured to be heat-resistant so as to protect one of the lower end, the sump, and a lower spray arm from heat emitted by the heating element. An associated apparatus and method are also provided.
