On my ideal standard Isar boiler, I'm getting a fault
reading "F" and "L" flashing and it's not firing. Can you please help me to identify or fix this. Many thanks
My boiler does that when there is no gas. We have a gas meter and when it runs out of credit the f and l flash up. Once we have gas i hold the reset button for 5 seconds and it fires back up. Dont know if this will help.
Good luck
