Frigidaire Dishwasher overheating
If your Frigidaire dishwasher is overheating, the problem usually starts with the heating system itself. The most likely cause is a shorted heating element or heating element assembly, which can raise water temperature beyond normal operating range and make the dishwasher get too hot. After that, check the high-limit thermostat, since a failed thermostat can stop regulating heat correctly, though it is less common. A thermostat that is out of position can also cause a Frigidaire dishwasher overheating issue because it may not sense tub temperature properly if it is loose or not seated in its support bracket. If those parts check out, the standard thermostat is another possible cause, and in some cases the incoming water supply is simply set too hot. For proper operation, dishwasher water temperature should be about 120 degrees Fahrenheit. If your dishwasher overheating problem points to a failed part, RepairClinic.com makes it easy to match the right heating element, heating element assembly, high-limit thermostat, or thermostat to your machine. Just enter your model number to find the exact replacement part for your specific Frigidaire dishwasher.
01 - Frigidaire 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 - Frigidaire 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.

05 - Frigidaire Dishwasher Thermostat
The thermostat monitors the dishwasher internal temperature and shuts off the heating element if the dishwasher overheats. 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.
Highly Likely
07 - Frigidaire Dishwasher Temperature Sensor
A defective dishwasher temperature sensor can allow the water being circulated to become too hot and overheat the appliance. You can use a multimeter to test the sensor to help determine if the component has shorted or is defective.
