  If your Lochinvar Water Heater's heat pump isn't running due to a high-pressure fault, ensure the thermostat setting does not exceed 160°F. Let the heat pump remain off until the room temperature returns to its operating range. Other potential solutions include replacing the unit pump, reducing piping or adding a booster pump, cleaning the heat exchanger with a mild acid wash, and ensuring all shut-off valves are open.

  If the heat pump of your Lochinvar Water Heater isn't running due to a low-pressure fault, allow the heat pump to remain off until the room temperature returns to its operating range. Address any air-flow issues by replacing or realigning the pulley assembly and tightening the belt at the adjustable pulley, replacing filters, or relocating the unit to allow for even airflow. Also, find the source of any leaks, repair them, and recharge the system.
