with machine off and fully disconnected from mains, turn machine on a slant check wires that connect to the pump are secure and connected / if pump has a white cap at the end remove anti clock wise and remove any foriegn objects also check waste hose for blockages.
if u have a multi meter u can also check connuity between the power wire connections on the pump itself u should have little resistance at all an open will indicate a faulty pump.
sometimes the door switch plays a part in draining , make sure this is operational in wash cycle lift lid up and of course it should stop .
good luck
