Answer:
Step-by-step explanation:
If the required max temperature needs to be 180 °F but the water temperature is hitting 200 °F then it is surpassing the desired temp and therefore failing to complete its purpose. Therefore, the next step would be to adjust the design and add a thermometer sensor to stop the water heater once the water temperature reaches the desired 180 °F. This would make the water heater serve its purpose as intended.
