No heat from radiators

[spiidey]

We're currently getting no heat from our radiators. Issue just started today.

Got a potterton boiler.

Picture of control panel below.

Does the orange light above the flame mean flame failure? If so, why are the red lights indicating the temperature at 30, 40 degrees on?

Have you tried resetting the boiler? (Turn the selector switch fully anticlockwise against the spring pressure to the reset position for at least 3 seconds and release)

Yes that worked!

What could have been wrong with it?

Is it something we should get a plumber out to have a look at?

When was the boiler last serviced? If 'never' or 'two or three years ago', it would definitely be worth getting it checked over.

Yeah a couple of years ago.

I reckon what may have triggered this is we seem to have a leak somewhere in our central heating piping system - a small leak but over time the pressure in the boiler seems to drop very slowly - when I checked the boiler when we were getting no heat, the pressure was about 0.2 bars so maybe the boiler just couldn't force the hot water round the system? I increased the pressure in the boiler back to 1.25 bars and reset the boiler which seemed to do the trick.

Either way agree we need to get it serviced.

Either way agree we need to get it serviced.

And find and fix the leak on your CH system.

Yes but save taking down our plasterboard walls I don't think that's feasible!!!

The pressure typically drops from 1.25 bars to 0.5 bars over a 3 month or so period.

I guess you've already checked all visible pipework then?

Have you considered a leak sealant?

Yep all pipework checked.

Not considered a leak sealant - how is this administered and how likely is it that it will catch the issue?

Depends on the type of leak as to its effectiveness.

Have you got a combi or a open tank in the loft?

Boiler is wall mounted flue condensing gas fired system.

Hot water tank (only tank in house) is in a cupboard in one of the upstairs bedrooms; has an electric immersion as well.

Pretty sure its an unvented system.

I believe that you will be applying them directly to your radiators then.

Have a read or fernox and sentinel products for leak sealant. You will be able to make an informed decision
