Does the washer not work at all, or does it just not work when it's trying to rinse? It may be a lid switch. If the washer does not work at all, it may be the timer. Pull the timer from the unit and check to see if any of the "fingers" are stuck, sticking, or burnt. If so, change it. The timer is the "Brains" of the washer... it tells it when to start, cycle, & stop. Sounds to me like this is more than likely your problem. The washer allowed water to be drawn in and then went to "L".
