I am needing information on a GE diswasher, model GsD2600G00BB. The dishwasher will not drain after a cycle is finished. There are no obstacles obstructing the drain upon examination. Upon manual operation of the solenoid, the water drained properly.I would appreciate your input as to what the problem is and how to repair.Sincerely,Sonny Thacker
