Ge super capacity plus model # wbse3120b2ww. machine will just stop in the middle of a wash cycle, most times if you push start it will resume. i replaced the control assembly, the problem is still there. yesterday when i pushed start it nothing happend. i switched it to spin and it just hummed. the rinse and spin lights flashed. i tried later in the day and pushing start worked and it finished the load. i've done two since with no problem. not sure what to check next. any ideas?
