frigidaire gallery dishwasher Mod. ph13878gcto

[krwinn]

my dishwasher is not draining, frigidaire gallery. I took the pump apart and found several pieces of plastic inside of it. they were gray., I checked the rotor inside the round white plastic filter device and found the rotor free from the shaft. do they have a site for a replacement part for what i need or should i just go buy new again. the pump makes a noise when it is tr ying to driain out th e water so i th ink it sucked a piece of plastic down itno the pump. how do i get to it. do i remove the expansion ring or will it drop t he motor on the floor?
