Bolier not working

[scousespark]

Good morning guys and Happy New Year to you all.

I have a Greenstar 25si which is playing up today. It was set to come on at 07:00 and it hasn't been working. The reset and operation light (the blue one) are flashing. The pilot light is off. When I switch it on, the operation light comes on and the reset light goes off. The pilot light comes on and I can hear water circulating. After a minute or so, the boiler starts making a rumbling sound and the pilot light goes off and the others are flashing.

I assume this is due the the weather, but wanted to check if there is anything I can do before getting an engineer out.

Can any of you advise please?

Frozen condensate pipe. You are the 300,000th victim this week.

Cheers mate. Looked for posts on condensate pipe and got out the hairdryer.

Look at a few more and get a kettle full of hot water!
