White-Westinghouse Dishwasher overheating
If your White-Westinghouse dishwasher is overheating, the most common cause is a shorted heating element or heating element assembly that keeps raising the water temperature higher than normal. A faulty high-limit thermostat is possible, but it is less common than the heating components themselves. You should also check that the thermostat is mounted firmly against the tub in the support bracket, since a thermostat out of position can misread internal temperature and let the dishwasher get too hot. In some cases, the thermostat itself can fail, and it is also worth confirming that your home water supply is not set above the recommended 120 degrees Fahrenheit. For a White-Westinghouse dishwasher overheating problem, these are the parts and conditions most likely tied to the issue, especially when the dishwasher gets too hot during the cycle or seems to be overheating consistently. Testing the heating element, heating element assembly, high-limit thermostat, and thermostat with a multimeter can help narrow it down. Enter your model number on RepairClinic.com to find the exact replacement part that fits your specific White-Westinghouse dishwasher.

03 - White-Westinghouse 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.

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.
