Often what appears to be a significant problem, may be something simple. I would recommend checking your lid switch. If the washer
fills and doesn't do anything, or stops right after the wash cycle and then does not advance to the rinse cycle and drain, this is commonly caused by a lid switch malfunction. The 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.
If not activated by a lid strike, other models have the lid switch located under the washer casing next to one of the lid hinges. It is activated by a rod contacting an actuator. The mounting scews for this type are located under the operator console.
