What to do if the temperature adjust buttons are stuck on my Lochinvar LVL07580?
If the self-diagnostic check on your Lochinvar Water Heater detects that one or both of the temperature adjust buttons are stuck, press and release both temperature adjust buttons several times, then cycle the water heater power off and on. If the error code persists, replace the gas control valve/thermostat.
What to do if my Lochinvar LVL07580 has ignition failure?
If your Lochinvar Water Heater is experiencing ignition or flame failure and is locked out after three retries, you can reset it by cycling the power off and on. Also, ensure the flame sensor is making good contact with the burner flame and the flame is steady. Check that the gas supply is turned on and pressure is adequate, and that supply and manifold gas pressures are within the requirements in the installation manual. Clean the flame sensor with fine steel wool. Also, check the igniter assembly plug and socket for a good connection. If the plug is worn or damaged, replace the igniter assembly. If the socket is worn or damaged, replace the gas control valve/thermostat. As a last resort, replace the igniter assembly.
How to fix earth ground issues in my Lochinvar LVL07580?
If the gas control valve/thermostat in your Lochinvar Water Heater senses inadequate or no earth ground, make sure the wall outlet (power supply) is properly grounded. Also, ensure all ground connections/wires on the water heater are securely connected.
What to do if my Lochinvar LVL07580 Water Heater has gas valve driver circuit issues?
If the self-diagnostic check on your Lochinvar Water Heater detects a problem with the gas valve driver circuit, internal microprocessor, or other internal circuits, turn the power off for 10-20 seconds, then turn it back on to clear the error codes. If the error codes persist or cannot be cleared, replace the gas control valve/thermostat.
How to troubleshoot an open igniter circuit in my Lochinvar LVL07580?
If the gas control valve/thermostat of your Lochinvar Water Heater detects an open igniter circuit, check the wiring to the hot surface igniter assembly, and replace the igniter assembly if the wiring is damaged or worn. Check the resistance of the igniter at the igniter assembly plug; it should be between 11 and 18 ohms at room temperature (77° F at plug end). Replace the igniter if it's open or shorted. Also, check the igniter assembly plug and the socket on the gas control valve/thermostat for a good connection. Replace the igniter assembly if the plug is worn or damaged, and replace the gas control valve/thermostat if the igniter assembly socket on the bottom of the control is worn or damaged.
What to do if my Lochinvar Water Heater's ECO is activated?
If the water temperature in your Lochinvar Water Heater tank exceeds 195° F and activates the ECO, turn the power off for 10-20 seconds, then turn it back on to clear the error codes. If the error code persists, replace the gas control valve/thermostat.
What causes the pressure switch circuit to remain open in my Lochinvar Water Heater?
If the pressure switch circuit remains open longer than 5 seconds after the blower is energized in your Lochinvar Water Heater, ensure the air pressure switch sensing tube is properly connected at both ends and is not kinked or damaged. Also, ensure the correct size of vent and intake air pipe (direct vent products) was used per the installation instructions in the manual that came with the water heater. Make sure the maximum number of elbows or maximum equivalent feet of vent or intake air pipe has not been exceeded per the installation instructions in the manual that came with the water heater. Finally, ensure there are no obstructions in the vent or intake air pipe.
What to do if the water temperature sensor is open or shorted in my Lochinvar Water Heater?
If the self-diagnostic check detects that the water temperature sensor in your Lochinvar Water Heater is either open or shorted, turn the power off for 10-20 seconds, then turn it back on to clear the error codes. If the error code persists, replace the gas control valve/thermostat.
What to do if the pressure switch circuit remains closed in my Lochinvar LVL07580?
If the pressure switch circuit remains closed for more than 5 seconds after the heating cycle begins in your Lochinvar Water Heater, ensure the air pressure switch circuit wiring is correct and the air pressure switch is not jumpered. If problems persist, replace the air pressure switch.
What to do if my Lochinvar LVL07580 has a problem with the black resistor wire on the ignitor assembly plug?
If the self-diagnostic check detects a problem with the black resistor wire on the ignitor assembly plug of your Lochinvar Water Heater, turn off the power to the water heater. Ensure the black resistor wire is not cut, missing, and is installed between pins 3 & 4 of the ignitor assembly plug. If damaged or defective, replace the ignitor assembly. If the error code persists, replace the gas control valve/thermostat.
