Abstract
A pump for pumping water from a bowl of a washing machine is provided. The pump includes a housing coupled to the bowl and a cover with an aperture. The housing and the cover define an interior in fluid communication with the bowl interior via the aperture. A filter filters water entering the interior via the aperture. The filter has a profiled wall defining a volute around the aperture, and a hood disposed above the wall. The profile of the hood perimeter substantially corresponding to the profiled wall to define a profiled space between the perimeter and the profiled wall. The profiled space allows water to enter the volute but substantially prevents elongated objects entering the volute.
