Amana Dishwasher overheating
If your Amana dishwasher is overheating, start with the parts most likely to cause excess heat: a shorted heating element or heating element assembly. Either one can keep raising water temperature past normal operating range and lead to a dishwasher overheating problem. Next, check the high-limit thermostat, then make sure the thermostat is firmly mounted against the tub and seated correctly in its support bracket, since a loose thermostat can misread temperature and let the dishwasher get too hot. A faulty thermostat is also possible, though less common. Before replacing parts, verify your home’s hot water supply is set close to 120°F, because water that enters too hot can also make an Amana dishwasher get too hot. If you are testing components, use a multimeter to check the heating element, heating element assembly, high-limit thermostat, and thermostat for a short or continuity problem as appropriate. To find the exact replacement part for your specific Amana dishwasher, enter your model number on RepairClinic.com and match your machine with the right heating element, thermostat, or related part fast.

03 - Amana 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.
