Abstract
A filtration system for a dishwasher, and an associated apparatus and method, are provided, comprising a macerator chamber adapted to house a macerator device. The macerator chamber is configured to receive washing fluid for the macerator device to comminute contaminants within the washing fluid. A drain chamber is in fluid communication with the macerator chamber and is configured to receive the washing fluid and comminuted contaminants therefrom via a fluid port therebetween. The drain chamber has a vented member associated therewith, which defines at least one first vent providing fluid communication between the drain chamber and the washing fluid circulation system. The vented member is spaced apart from the fluid port, and is configured to strain the comminuted contaminants from the washing fluid so as to retain the comminuted contaminants within the drain chamber while allowing the washing fluid to pass therethrough to the washing fluid circulation system.
