To reset your boiler, locate the reset button on the control panel. Press and hold it for 3-5 seconds until the reset light turns off. If the fault persists, contact a professional engineer.
First, turn off the water supply to the boiler and power it down. Check all visible pipes for cracks or loose connections. If the issue is not apparent or persists, contact a qualified technician.
Locate the filling loop, usually beneath the boiler. Open the valves until the pressure gauge reads between 1 and 1.5 bar. Close the valves after the pressure is adjusted.
Regular maintenance includes annual servicing by a Gas Safe registered engineer, checking and cleaning filters, inspecting the pressure relief valve, and ensuring the flue is unobstructed.
Banging noises, often referred to as "kettling," can be caused by limescale build-up on the heat exchanger. This issue can be resolved by a professional who will clean or replace the affected parts.
A flashing red light typically indicates a fault. Refer to the user manual for specific fault codes and their meanings, or contact a professional engineer for diagnosis.
Turn off the heating and wait for the radiators to cool. Use a radiator key to open the bleed valve and release air until water starts to drip out, then close the valve.
Possible causes include a faulty thermostat, issues with the heat exchanger, or inadequate water pressure. Inspect these elements or consult a professional for a thorough check.
To set the timer, turn the dial to the current time. Use the pins around the dial to set the desired on and off times. Refer to the user manual for specific instructions related to your timer model.
Check if there’s a power outage or if a circuit breaker has tripped. Ensure the boiler’s power switch is on. If the issue continues, contact a qualified electrician or boiler technician.
