Potterton Prima F50 Boiler won't stop igniting but no heating or hot water

[GeorgeN]

Hi all,

I hope this is the right category.

I woke up this morning in a cold house with no hot hot either. (It's a rent flat).

My boiler Potterton Prima F50 is continuously running, I can see fire inside, it's making the usual noise apart of that gurgling water noise.
I checked the thermostat, the programmer, all fine. The thermostat makes that click when I turn it but it doesn't seem to switch on/off the boiler.
The red pump seems to be running, it makes a buzz. All pipes around the tank are cold.
The valve is on Hot Water position at the moment.

Back to the boiler, it appeared that it lost some pressure. The gauge was lower than usual and I saw a bit if water under the overflow pipe outside the building. I topped up the preasure to 1 bar (as usual) but still no luck.

I have British Gas coming in tomorrow but I wonder if is anything I can do to get some heating tonight?

Thank you

Well, I don't mean taking the boiler apart but sometimes can be a quick fix.

I just wonder if it's the boiler or it's a fault within the system (pipes, valve, punp etc)?

I think you've checked all the obvious stuff.

Fortunately, it's National Hug a Plumber Day so if you need to keep warm you just need to find a plumber and hug them real tight.

Sounds like a stuck diverter valve to me, not a diy or five minute fix.

Thanks, British Gas got it fixed. The PCB was faulty.
