Check your lid switch. If the washer fills, agitates, then stops at the rinse cycle and won't drain, or if the washer does an initial fill, then stops, this is a common symptom of a lid switch malfunction. The "buzzing" noise you hear is probably the timer motor running.
This is a very simple and inexpensive repair. The following link explains how to access and/or replace one:
http://www.fixya.com/support/r385198-replacing_lid_switchThe lid switch is usually mounted under the
washer top casing, on the right hand side on most top load models. It is activated by a plastic piece on the lid (called a "Lid Strike") through a small hole on the
rim of the wash tub opening. In many cases the lid strike breaks off the lid, or the lid switch becomes loose and no longer makes contact. Inspect the lid to make sure the lid strike is still intact, and then inspect the mounting screws (adjacent to the small opening on the wash tub
rim) and make sure they are snug.
On some models, the lid switch is located under the top casing by one of the lid hinges. You will know if you if you have this type of switch, because It does not have a lid strike and the small hole on the right hand side of the wash tub will not be present. This switch is actuated (toggled) by a rod on the lid hinge. With this type of switch, if you locate it and it can be toggled by hand, you may only need to adjust the actuator by bending it slightly.
