Yes it's a timer issue. I opened one once and seen that the following may work.
Sears repair tech told me the points in the timer can stick together. Try this, works sometimes: spin timer around as fast as you can 2 or 3 times, if the points are stuck, this can cause them to release. Other that that? Timers are expensive, unless you get one off a machine that is put out for pick up like I did. People toss these machines for such silly reasons. There's good parts on most of what gets tossed. Here's how to remove the control panel if needed:
Disconnect the power cord. Turn off the water. There is either two screws, one at each front corner, holding the control panel in place or hidden clips. 1. If you see the two screws remove them. If no screws are visible you have a clip at each front corner of the control panel. The best tool to use to unhook these clips is a putty knife. From the front push the putty knife between the machine top and the control panel at either outer corner of the control panel . You will feel a spring tension. Push firmly, but not to forcefully toward the back. When the spring releases the control panel corner will lift easily. Repeat at the other corner. 2. Now, if there was two screws holding the panel, remove the two screws at the top on the back of the control panel. If just clips, simply and carefully roll the control panel over the back.
