1. A washing machine pump for installation in a washing machine with a bowl adapted to hold water in an interior portion, the pump being adapted to be coupled to the bowl and to pump water from the bowl, the pump comprising:
a housing for coupling to the bowl and a housing cover with an aperture, the housing and housing cover arranged to define a housing interior that is in fluid communication with the bowl interior portion via the aperture, and a filter for filtering water entering the housing interior via the aperture, wherein the filter comprises a profiled wall extending from the housing cover and encircling the aperture to define a volute around the aperture, a hood disposed above the wall, the hood having a perimeter, said perimeter having a profile wherein at least one of the perimeter and profiled wall are non-circular when viewed from above, said hood having a lip extending downwardly from the perimeter of the hood toward the housing interior so as to overlap the profiled wall and to thereby define a profiled space between the lip and the profiled wall, the profiled space extending around the volute, and wherein the hood forces all water passing through the profiled space toward the housing interior to travel therethrough upwardly, away from the housing interior, the profiled space allowing water to enter the volute but substantially preventing elongated objects from entering the volute. |
