ideal isar he30 problem

[Daniel79]

hi,hope someone can help me,
as per title i have an ideal isar he30 boiler and i got the fault code L F i looked on different site and saw it said to reset the boiler,as the boiler doesnt have a reset button or a manual with it,it took abit of button pressing to work out u hold prog and select to reset,it worked and the boiler cam back on but if i turn the heating or hot water on it makes a noise like its firing up then after about a minute or so it brings the fault code up again.if i set the water and heating to off it will stay on!can anyone give me any suggestions as to whats wrong please?

Do you have gas? If yes, then it’s probably an internal fault such as the gas valve, ignition, spark electrodes, and other gas engineer related stuff.

No you just press the select button

You have a itime programmer, here is the manual for it

The LF code is flame lockout, most common problem is a blocked condensate trap if @The Novice said you have checked that the gas supply is actually on
