What does C1 mean on boiler?
A C1 fault code is generated when the fan has stopped during operation. This should not be confused with other fault codes whereby the fan is running too fast or fan running too slow. Things to check are fan, harness and control box. This should only be carried out by a Gas Safe registered engineer.
How do I reduce the pressure on my British Gas boiler?
Wait for the water pressure to reach between 1 and 1.5 on the pressure gauge. Once it has, shut off both valves one after the other. Switch the boiler back on and, if needed, press the reset button. Undo both ends of the filling loop and remove from the pipes.
Where is boiler pressure relief valve?
This is called the Pressure Relief Valve Discharge Pipe (or commonly called the ‘P.R.V. ‘) It’s a small pipe, which can only be seen on the outside wall of where the boiler is installed.
What should pressure gauge read on combi boiler?
between 1 and 1.5 bar
The pressure of your combi boiler should be between 1 and 1.5 bar when the system is OFF & the water is COLD. It is perfectly normal to see your gauge rise when your heating system is on & the water is hot. If your pressure is less than 1 bar, it’s possible that you have lost water from your system via a leak.
What does LC mean on gas boiler?
What does my Ideal Boiler Fault Code mean?
Fault code | Fault |
---|---|
L2 | Ignition lockout – you can manually fix this with our frozen condensate guide here |
L6 | False flame lockout – reset your boiler and this should fix the issue |
LC | 5 boiler resets in 15 minutes – turn the electricity to your boiler off then on to fix the issue |
How do I know if my pressure relief valve is bad on my boiler?
To check if the fill valve is the problem, turn the boiler off, allow it to cool, drain some of the water until the pressure reaches 10psi. Don’t turn the boiler back on and wait if the gauge starts to go up again. If it does, then the fill valve may be defective.
How is pressure maintained in a combi boiler?
Pressure in most modern combination boilers is maintained by a ‘filling loop’, which connects to your cold water pipe. We’ll come back to this! 2. What causes a drop in pressure? There are two leading culprits when it comes to low water pressure: You may have a leak somewhere in your boiler system.
How do I re-pressurise my boiler?
Re-pressurising your boiler means allowing more water to enter the system, from the water mains supply, via the filling loop. The two main types of filling loop are ‘built in’ and ‘external’. Undo both ends of the filling loop and remove. Be careful to catch any water spillage, and keep the filling loop in a safe place!
How do I reset the pressure gauge on my boiler?
Open both valves, to allow cold mains water into the system (you should hear it) Wait for the pressure gauge to read 1.5 bar. Close both valves, one after the other. Switch the boiler back on and, if needed, press the reset button. Undo both ends of the filling loop and remove.
What should I do if my boiler pressure is low?
If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced. This is where that filling loop (or filling link) comes in again!
