Question

I have a Kenmore dishwasher model 665. The thermal fuse 675813 keeps blowing. I have replaced the pigatils off the board that are supplied with the fuse kit. I was told by a Sears auth. service rep to keep the door filter clear. I do that with every cycle. Any suggestions short of burning this thing and throwing it off a cliff?
