We have a kenmore washing machine top load model 110. The machine stops on the spin cycle but will advance if you push in the button on the machine top with a pencil and hold the pencil in place. The little pin on the lid doesn't seem to push it in far enough. Also if you push down on the lid in the corner where the pin and button is it will advance but it doesn't stay on. Is it the timer or the button in the machine top that is the problem/

You just solved the problem yourself. Replace you lid switch or replace the actuator on the lid.

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 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 you determine the switch to be defective, the following link explains how to replace one:

Yes if the lid switch dont stay in and make contact the washer thinks the lid is open and shuts down.
