How can i fix my washig machine Samsung WA80U3 top loading?

Samsung WA80U3 Top Loading machine is giving an Error Code UE. Before it was like SE Or 5E , I drain the water manually and its started its cycle and at last the machine goes on idle and flashes on the spin mode. When I try to drain it again manually ,my machine takes water again and finally goes on the UE fault code. Please help. Thanks
