I have a Kenmore front load washing machine that spins to slow and may not be completing final spin cycle out starts and quits repeatedly. I have replaced the main control board, motor control board and the motor. I'm just frustrated at this point. Sears specialists can't seem to tell me what is wrong or what to do next but I'm certain its fixable and i don't need to pay one of their technicians to come out and not be able to fix it when they can't even tell me what to try now. Please help.
