Alternating F A code on boiler but fault code not in manual

Hello I have an Ideal Logic Combi 30 boiler which is covered by warranty etc as installed in a new home. We've had numerous problems with the boiler and several engineers out including Ideal engineers but they are not solving the problem. The boiler is now showing an alternating F and A fault code but this isn't even in the user manual! Does anyone have any ideas or shall I just insist on a new boiler?! Thanks in advance!!

SOURCE: ariston A01 fault combi boiler

the A01 fault code is nearly always down to the pcb, 99% of the time in fact, its a common fault, but not common enough for ariston to be responsible for boilers out of the warantee. you can normaly check this yourself, while the tap is running check if the electrodes are still sparking even after the gas had lit, this means the pcb is not detecting the flame and trying to relight. eventualy it will lock out with a A01 code, if u reset it might work for a short time but eventualy u will get to the stage where it will no longer resart.
if your handy you can replace the pcb yourself, there is someone selling them on ebay for £85 thats a steel, its half the trade price never mind retail price!
pcb part number is 65103422 just search it on ebay!

SOURCE: Rheem RTG 53 PVN with fault codes C4 or C7

I had the same problem with my tankless waterheater (flashing c4 76 alternately). I called Rheem
tech support and they had me 1 power down the remotepanel 2 unplug the unit from the wall 3 remove the cover 4 remove the wires for the remote panel from the circuit board and pull the twisted pair that goes to the remote out from the bottom of the unit. 5 reinstall the cover 6 plug the unit back
into the wall and turn on the hot water see if it works. It did in my case and they are sending me a new remote panel. I hope it helps.........

SOURCE: I can't turn the bar pressure up on my Vaillant VCW 221 Boiler

on the pipework below there may be a silver braided hose with one or two valves on the end. turn the valve(s) so the handle is inline with the pipe this will allow water from the mains supply into the heating circuit , remember to keep an eye on the pressure gauge. fill the system to 1bar cold then shut down the valve(s). turn on the boiler and it should be ok, if you lose pressure again then you may have a leak somewhere which needs to be found.

most have an overrun built in for a few minutes. if much longer have you got a room thermostat anywhere to turn down
If it never turns off check the switch which controls ON/TIMED/OFF and turn to timed or off. if it still continues on timed then it's the timer

My ideal logic combi 30+ is saying ignition lockout and my radiatiors arent heating up as well as my water not turning hot. How can i fix this please?


Lockout is a safety feature. Usually a latching condition and needs to be investigated rather than blindly reset. (The Combi has a bit more intelligence.) With the ignition locked out, you can't hi-fire the boiler, so no hot water of either type. The 'L' should also show a code number - check your user manual (google) for more guidance.

I've had a lockout on a non-combi: it was caused by lack of circulation of central heating water through the boiler.... The system boiled and the trip tripped. The pump WAS running, but wear in a valve actuator resulted in the valve feedback saying valve open while it was physically shut.

Ideal icos 18 fault code HF


According to pages 47-50 of the install guide, section on FAULT FINDING, the alternating H and F indicates Flame Detection Short Circuit Error. Actions are: Remove flame detection electrode terminal from PCB. Test for continuity between 2 terminal pins? If YES, replace flame detection electrode. If NO, replace PCB.
