I have an Ideal Combi boiler, which is 6 months old. Every few days I get an LF (Flame Detection Error) error. Which states failure to ignite. and we get cold water.
Various engineers have looked at it and cannot pinpoint the problem.

- Combi Boiler Water Pressure Issues?
We recently had a combi boiler installed in our rented property. Initially the plumbers left the cold water feed from the tank in the loft so the combi boiler was only supplying the hot water. Unfortunately due to the differing pressures (i think), the cold water feed was excessive whilst using the shower the overflow pipe from the loft rained from the side of the house. The plumbers have since rectified that problem by removing the cold water tank and using the boiler to supply both the hot and cold. Unforunately the water pressure is now so low that it takes 30 mins to fill the bath. Also the shower now operates too hot and eventually (after a few mins) runs cold then hot again. Any help would be appreciated.... - Combi boiler pressure drops below 0 overnight and rises over 3 when on?
I’ve got a pretty new Heatline Vizo Condensing Combi Boiler. Everything was fine for the first couple of months and pressure held steady at 1.5 when cold, and rose to around 2 when the heating was on. Over the past few weeks, the water pressure drops below 0 turning the boiler off regularly. I can refill to 1.5 before going to bed, and it will be back below 0 in the morning. When I refill to 1.5 and have the heating on, the boiler pressure now rises to the maximum of 3. When the heating turns off, the pressure will drop again, eventually to below 0 within the space of maybe 8 or 9 hours. Whats going on? I cant find any obvious leaks (although the plumbing is underfloor), and there is no air in any of the rads. Ive drained and refilled the entire system a couple of times, but this has made no difference.… Read the rest...

Could be any number of things.
Air intake restricted
Exhaust restricted.
Fan not operating correctly.
Flame sensor out of position.
Even a fault with the electronics.
Don’t fiddle with it if is only 6 months old..
Still under warranty..
If you are not happy with the repair ask for it to be replaced.
if they don’t…contact consumer rights
I dont know what u mean by engineers im guessing u mean plumbers but it sounds like to me thatr u dont have enough gas volume at the unit for it to ignite…..did u have anything on gas before this was added?…..also if u already had gas…did the installers size the line right to add that extra amount of BTU’s that the unit would be pulling?…..theres alot of things that can go wrong with gas heaters,furnaces etc etc,….also the combi boiler sounds alot like a Rinnai water heater…..since it is still under warranty i would get the guy to come back out again and ask them to make sure there is enough gas volume going to the unit….they can test this using a manometer and see what the water column is…..thats what it sounds like to me is ur not getting enough gas to the unit
