buzzing/growling LG wm3431hs during draining
"I ended up testing all wires to pump and through noise filter. everything appeared to be working properly. took fan apart again and took some length off the stator blades. also filed a little off the inside of the pump assembly. I think the pump assembly is possibly warped but the piece is discontinued. might try to buy a different pump and assembly that will fit. i also put some packing foam around the pump. it better than it was but far from quiet.
thanks for the help gentleman"
