My baxi combi 105he, the red light is flashes on the 30 degrees light which is telling me that the flame failure or the blocked condensation pipe is the problem. i have tried to defrosted the pipe and this has not worked , the flame will kick in after resetting but goes out shortly after. can you please help

Try a power reset. Fully disconnect power to it for 15 minutes. Then try again.

It does appear to be a known fault. If that doesn't fix it, you will need a gas certified heating technician.

F2 is flame loss check the condensation pipe is not blocked or cracked

Indicates low water flow. possibly bad electrical connection to flow detector in dhw pipe or seized dector in pipe or blocked up heat exchanger. certainly a blockage somewhere in the pipes

Sounds like its an intermittent flame failure on trial for ignition. Look for the pilot flame drifting away from the sensor when the main valve opens.

Make sure the gas inlet & outlet pressures are correct (manometer) & that the primary air mixture is adjusted correctly. Check to make sure you have 1 square inch of outside air for combustion per 2000 BTU's rating on the boiler.

yes a combi boiler has to be piped so they would cut off the pipes to your baxi and you can ues it as a gas fire only

is the boiler a combi if so have you checked the pressure. it needs to be at 1.5 bar 2 bar at the most . also check that the heat the boiler is producing is completeing the circuit on the heating if you have access to the pipe work there should be 2 or 3 22mm copper pipes. now turn the heating on and check which one is getting warm. the one that is is your flow and in about 2 to 3 min there should be one more pipe getting hot let me no if this is the case

is boiler still under warranty?
normal warranty lasts at least 2 years
if so get ideal to send one of their engineers out
L2 relates to flame failure
either boiler has failed to ignite
or
boiler has not detected flame once lit

several causes

failure to ignite
ignition electrode/spark generator

failure to detect lit flame
detection electrode/detection lead

blocked condensate pipe
or defective condensate syphonic trap

you really need an engineer to check these components

Try using a good hair dryer to defrost the entire condensate pipe and I believe your problems will be solved.

Check the temp
