If you smell gas, immediately close the mains gas valve, avoid operating any switches or using open flames, ventilate the boiler room, and contact your installation engineer or local gas company.
What causes the F05 Flame error on my Lochinvar EcoSword LGC 285-560 PG P CE Water Heater?
A (lock out error) F05 on your Lochinvar Water Heater, indicating too many flame failures, can arise from a few key issues. First, check for recirculating flue gases due to an incorrect roof or wall flue terminal, ensuring it's correctly installed and there are no leaks in the venting system. Also, verify that the flue terminal discharges into a permitted area and that the CO2 values are correct in both the flue gas outlet and air inlet. Ensure there is sufficient gas supply pressure. Finally, check that the supply voltage to the controller is correct, and if it's not within tolerance, contact your maintenance and service engineer or install an isolating transformer.
How do I troubleshoot a F02 Fan error on my Lochinvar Water Heater?
A (lock out error) F02 on your Lochinvar Water Heater, indicating a fan error where the fan does not run at the correct speed, can be caused by several issues. First, check the wiring between the fan and the controller for damage or disconnection, replacing or reconnecting as necessary, and then reset the controller. Next, inspect the fan for contamination or blockages, cleaning or removing any obstructions, and ensure the rotor can rotate freely before resetting the controller. Verify that the supply voltage is correct (230 VAC -15%, +10%), and if it's not, contact your maintenance and service engineer. Finally, check the motor and rotor for defects, replacing the fan if necessary, and reset the controller.
What causes an incorrect CO2 value in my Lochinvar EcoSword LGC 285-560 PG P CE Water Heater?
A CO2 value that is not correct (at full load) in your Lochinvar Water Heater can be due to several reasons. Ensure the unit is set for the correct gas type, matching the rating plate information, and that the venturi restrictor has the correct diameter. Check for and remove any contamination from the venturi inlet. Inspect for leaks between the venturi and flexible venturi connector, ensuring the connector is not damaged and is correctly connected, tightening the clamp if necessary. Also, verify that there is no recirculation of flue gases by checking the CO2-value in the flue gas outlet and ensuring the CO2 value in the air inlet is below 0.5 vol%. If needed, reconnect the venting system and replace any seals.
How to fix a F04 Ignition error on my Lochinvar Water Heater?
A (lock out error) F04 on your Lochinvar Water Heater, indicating an ignition error with three unsuccessful attempts, can stem from several issues. Start by ensuring the main and manual gas supply valves are open and that the gas supply pressure to the gas control valve is correct. Also, check for air in the gas pipes and bleed it out if necessary. Inspect the hot surface igniter circuit for correct installation, wiring damage, and proper resistance (36-72 Ohms at room temperature), ensuring it lights up during ignition. Similarly, examine the ionization circuit for correct flame probe installation, wiring integrity, and a minimum ionization current of 3 µA. Finally, verify that the supply voltage is correct and that the flame probe is not bent or has a broken ceramic part.
Why does my Lochinvar Water Heater have explosive ignition?
An explosive ignition in your Lochinvar Water Heater can be caused by several factors. Check the gas supply pressure and CO2 value. Also, the burner may be contaminated and needs cleaning. Finally, inspect for air leaks between the venturi and the flexible air connector, ensuring the connector is not damaged and is correctly connected and tightened.
What to do if my Lochinvar Water Heater is leaking water?
If you notice water leaking from your Lochinvar Water Heater, there are several possible causes. First, check for leaks from any threaded water connections and tighten them if necessary. If the leakage is condensate, ensure that the condensation water discharge is working correctly and correct it if needed. Also, inspect the surrounding area for leaks from other water heaters or pipe segments. If the leak appears to be coming from the water heater tank itself, contact your supplier.
Why is the display off on my Lochinvar Water Heater?
If the display on your Lochinvar Water Heater is off, there are a few potential causes. First, ensure that the water heater is turned on. If it is on, check the power supply by verifying that the control switch is set to 'I', the isolator is in the 'ON' position, and there is proper voltage (230 VAC -15%, +10%) at the electrical connector block. Also, check the fuse(s) and replace them if they are defective.
Why is my Lochinvar EcoSword LGC 285-560 PG P CE not producing enough hot water?
If you have insufficient or no hot water from your Lochinvar Water Heater, it could be due to several reasons. First, ensure the water heater is turned on. Next, check the power supply, verifying that the control switch is set to 'I', the isolator is in the 'ON' position, and there is proper voltage (230 VAC -15%, +10%) at the electrical connector block. Also, make sure that the controller is in the ON mode and the temperature is set high enough. Finally, consider whether the hot water supply has been used up, and if so, reduce consumption and wait for the water to reheat.
