My Kenmore 665 dishwasher"s normal wash led light is flashing continuously and does not go off. I tried pressing the high temp and normal wash button alternately for seven times, but it did not help. I noticed that when I press and hold the drain/cancel button the normal wash light goes off but as soon as I release the drain/cancel button the light comes back on. I cannot get the washer to start, can someone help me, any solutions?
