You can test your dishwasher heating element by running a Sanitize wash cycle. If the Sanitize light on the control panel is blinking or doesn’t light up, there may be a problem with the heating element and you may need to schedule a service appointment.
If your dishwasher doesn’t have a Sanitize Cycle, you can test the heating element by selecting the 1-Hour Wash Cycle with the Heated Dry Option. Once the cycle has ended, check to see if your dishes feel warm. If they aren’t warm, there may be a problem with the dishwasher heating element.
