Samsung dishwasher was blinking Smart and Normal lights suggesting high temperature sensor warming. dismantling the part did not show any signs of abuse. The dishwasher was only 14 months old! Originally Samsung parts sent me the wrong part (metal plug looking thing held in by screws). Appliance parts pros sent the correct part for 1/4 of the shipping price. I wish I had came here first. After installing the new part, the fit was looser than the original. I added an O-ring where there previously wasn't on the new part and she seals up fine now. Dishwasher is working great now.
