Ideal Isar boiler error.

[Michael.]

Hello,
I have a problem with my boiler and hope someone can give me advice. It is an Ideal Isar and the status is flashing F.H. The boiler is firing up but I don't have any hit water or heating. Any suggestions what the problem is?
Thanks, Michael.

Hi, It's a flame detection problem. You need a GS Engineer to check it out.
