Central heating not working

[Barkern]

Hi, I am hoping someone might have some advice for me. We have woken up this morning to no central heating. We do still have hot water. It's a green Star junior boiler. The blue light comes in and stays on, the green light comes in then goes off. The pressure seems fine.

We are very much not boiler experts, though I have managed to repair washing machines, tumble dryers and plumb in a tap with the help of many YouTube videos so not averse to having a go something if it's a simple fix. Recognise that this is probably baby Beyonce me though!

It is looking like we need to call someone out..... The trouble is we all have covid so not really an option!

Any suggestions would be greatly appreciated.

I’m not a heating engineer but it could be a problem with the diverter valve, assuming it’s a combi boiler.
That the problem with mine except I’ve heating but no hot water.
