Maytag Dishwasher overheating
If your Maytag dishwasher is overheating, the problem is usually tied to the heating circuit, not the wash system. The most common cause is a shorted heating element, followed by a shorted heating element assembly that keeps raising water temperature past normal operating range. After that, check the high-limit thermostat and the regular thermostat, although both are less likely to fail than the heating element itself. It is also worth making sure the thermostat is mounted correctly against the tub, since a loose or out-of-position thermostat can misread temperature and let the dishwasher get too hot. In some cases, the dishwasher overheating issue is not a failed part at all, but water supply temperature that is set above the recommended 120 degrees Fahrenheit. If your dishwasher gets too hot, testing these parts with a multimeter is the fastest way to narrow it down. RepairClinic.com makes it easy to match the right Maytag 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 dishwasher.
01 - Maytag 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 - Maytag 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.
Highly Likely
05 - Maytag 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
