How to troubleshoot Elnur Boiler that will not start?
If your Elnur Boiler is not starting, first check the incoming power supply. Also, ensure the boiler control switch is turned on. If there was a heating overheat, locate and reset the tripped switch.
What does fault E3 on Elnur Boiler mean?
If you see the E3 error displayed on your Elnur Boiler, it relates to the heating system water flow switch. Start by checking if the pump is turning freely; refer to section 5.5 for guidance and replace the pump if needed. Ensure to purge the system thoroughly and check that the automatic air valve is open, and vent the pump (sect 5.5). Finally, verify the pump speed is at 3, check the pump duty (sect 4.9b), open all radiator valves, and install a system by-pass, because the system resistance might be too high or there might be a blockage.
What to do if Elnur Boiler heating system water is discharging from 3 bar safety valve?
If the Elnur Boiler system water is discharging from the 3 bar safety valve, it indicates excessive heating system pressure. Check that the filling loop has not been left connected or is letting water pass; disconnect the filling loop hose. Also, verify that the expansion vessel is charged to the correct level with air and check the system expansion volume.
What does fault E8 on Elnur Boiler mean?
If your Elnur Boiler displays Fault E8, it indicates a problem with the outdoor temperature sensor, which might be defective or not present. This sensor is optional. Check the connections and replace the sensor if necessary. Also, check if the parameter settings are correct (sect 5.1).
Why is my Elnur Boiler heating temperature low?
If you are experiencing low heating temperature with your Elnur Boiler, verify the temperature and output settings are appropriately selected. Also, check the heating elements for failure and replace them if necessary. Finally, recalculate and reconfigure to see if heat requirements were miscalculated.
Why the buttons on my Elnur Boiler do not respond?
If the buttons on your Elnur Boiler do not respond, it might be because the control panel is blocked. Please refer to Section 6.8, BLOCKING THE CONTROLS, for instructions.
How to fix E3 Error on Elnur Boiler?
If you see the E3 Error on your Elnur Boiler and need to address system by-pass requirements, ensure the heating system has sufficient water pressure by re-filling it to 1.5bar. Check the pump for circulation issues or seizure, referring to Sect 5.3. Also, closed radiator valves (Thermostatic) may cause the problem. It may be sufficient to maintain one radiator with permanently open valves; however, current Building Regulations recommend fitting an automatic by-pass valve.
What does fault E1 on Elnur Boiler mean?
If your Elnur Boiler displays fault E1, it indicates an issue with the heating flow temperature sensor. The heating water out temperature probe may be defective, and you should contact Technical Service.
What does fault E2 on Elnur Boiler mean?
If your Elnur Boiler displays fault E2, it indicates an issue with the heating return temperature sensor. The heating water return temperature probe may be defective, and you should contact Technical Service.
