I have an Ideal Independant C30 boiler that has low water pressure, there are 4 taps underneath and I do not know which ones to turn to bring the pressure back up - any help please?

My boiler says l2 Iv tried resetting it but no luck now it's saying 0 and the water and heating still isn't working. Can you give me any advice please

There will probably be a short flexible hose with a tap at each end underneath the boiler. When both taps are open, typically when the handles are in-line with the hose, mains water will enter the system.
Keep watching the pressure gauge and turn back off at both ends once the pressure reaches around 1.5 bar.
