Samsung Dishwasher overheating
If your Samsung dishwasher is overheating, the most likely problem is a shorted heating element or heating element assembly that keeps raising the water temperature past normal operating range. A dishwasher overheating can also happen if the high-limit thermostat is not controlling heat correctly, if the thermostat is loose or out of position against the tub and cannot sense temperature properly, or if the main thermostat has failed. In some cases, the dishwasher gets too hot because the incoming household hot water is set above the recommended 120 degrees Fahrenheit. If your Samsung dishwasher overheating issue is tied to a bad heating element, heating element assembly, high-limit thermostat, or thermostat, you can confirm the failure with a multimeter before replacing the part. Checking thermostat placement is also worth your time, since a misaligned thermostat can cause the dishwasher to overheat without an electrical failure. Enter your model number on RepairClinic.com to find the exact Samsung replacement part that fits your specific dishwasher and match the repair to your machine.
01 - Samsung Dishwasher Heating Element
A shorted heating element may be raising the temperature of the water beyond what is normal for proper operation and causing the dishwasher to overheat. You can use a multimeter to test the heating element for a short to help determine if the component should be replaced.

03 - Samsung Dishwasher High Limit Thermostat
The high-limit thermostat monitors the dishwasher internal temperature and shuts off the heating element if the dishwasher overheats. If the high-limit thermostat is malfunctioning, it may shut off the voltage to the heating element circuit. However, this is rarely the case. Before replacing the high limit thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity.
Highly Likely
04 - Thermostat out of position
The thermostat should be firmly pressed against the tub. If the thermostat is loose or is not in the support bracket correctly, it will not sense the water and air temperature properly, and can cause the dishwasher to overheat.

If the thermostat is malfunctioning, it may shut off the voltage to the heating element circuit. However, this is rarely the case. Before replacing the thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to check it for continuity.
Highly Likely
06 - Water supply temperature too hot
The water supply temperature may be too hot. The recommended water supply temperature for a dishwasher to clean properly is 120 degrees Fahrenheit (49 degrees Celsius). If your hot water temperature is higher, it should be turned lower for safety reasons.
