Our Kenmore Model 796-4027-2900 washing machine recently developed a problem where it won't power up. After researching, I came upon a tip to unplug it, then hold the power button down for 5 seconds and release, then hold the start button down for 5 seconds and then release it, then plug it back. AND IT WORKS. But this process needs to be repeated with every load of laundry. It is my understanding that this machine is manufactured by LG, but i don't know that for certain. What could be causing this failure to repeat after every load of laundry?
