To reset the boiler, locate the reset button on the control panel. Press and hold the button for a few seconds until the system restarts. Ensure the boiler is not in lockout mode before attempting a reset.
An annual maintenance check is recommended, including cleaning heat exchangers, checking burner operation, inspecting seals, and testing safety devices. Consult the user manual or a professional technician for detailed tasks.
Ensure regular maintenance, bleed radiators to remove air, install a programmable thermostat, and consider upgrading insulation in your home to reduce heat loss.
Unusual noises may be due to air in the system, a failing pump, or limescale buildup. Bleeding the radiators and checking the pump operation might help. If noises persist, contact a professional technician.
Turn off the boiler and isolate the water supply. Check for obvious sources of the leak, such as loose connections or damaged seals. Contact a qualified technician to assess and repair the issue.
Adjust the water temperature using the control panel. Refer to the user manual for specific instructions on navigating the menu and setting the desired temperature.
Frequent cycling may be caused by thermostat issues, incorrect water pressure, or a blocked heat exchanger. Ensure proper thermostat settings and check system pressure. Contact a technician if the problem persists.
Check the thermostat settings, ensure radiators are bled, verify correct water pressure, and inspect the pilot light or electronic ignition. If the issue continues, consult a professional technician.
A blinking error code indicates a fault in the system. Refer to the error code chart in the user manual to diagnose the issue. Reset the boiler if necessary and contact a technician for unresolved problems.
