Adjust the temperature setting on the unit to a comfortable level.<br />4. Inspect the gas or electric supply to the unit to ensure it is functioning properly.<br />5. Consider installing a water softener if hard water is causing issues with the heater.<br />6. Have a professional plumber inspect the unit for any potential issues or malfunctions.
