buy what your tellin me it could be motor or some thing jammed in pump, like sock. motor+pump are conn ected sometimes it may be timer .you woul have to remove fron cabinet to acess pump +motor .remove pump clips ,pull off pump . turn machine on if water is still in tub ,see if motor runs in agitation cycle .if it does problem may be pump .you would have to remove pump hoses to look in ports its best to shop vac water ou of tub +clamp off drain hose from tub to pump, i usually jump connection to lid switch to effect spin .being this is intermitant problem may still be motor or timer even if you get motor to run .you can remove motor +try on its own
