I had a "High Temperature Sensor" code blinking light on my Samsung DW. I replaced this sensor. Pulled DW out, lay it on it's back and removed 2 screws from the bottom tray. It takes about 1min to replace the sensor. The new part did not come with the rubber gasket/seal so keep the old one. Put everything back and DW works fine. It takes longer to disconnect the DW and pull it out than replace the sensor.
