1 1/2 yr old LG WM3470HVA-4 turns itself on then seconds later off again. Repairman replaced all 4 circuit boards- problem is still there. I found several websites referring to many models having this problem. Any help will be appreciated.
Get the repair man back & tell him to fix it. You have paid for a service that you haven't received. He should be either putting the old boards back or at least giving you a credit for the parts wrongly replaced that didn't fix the problem.
