Repressurising Worcester 2000

Gers

This morning the heating didn't click in and the remote unit has a message to refill the pressure.  The unit was installed last October.  The instruction booklet tells me to refer to the instructions given by the installer, well that one flew over my head. The heating engineers are not doing on-call at weekends because of staffing issues!

I have searched the net, watched endless videos of engineers reviewing this particular model and none mention how to refill it, there is nothing obvious on the boiler and certainly no key.  The display reads LoPr. Here's a picture of it:

I touhed the green thing, it turns yellow'ish and beeps though nothing happens.  I've turned the boiler off and touched the now blank thing.

Can anyone tell me how to refill the pressure please, it must be obvious and I'm missing it.  I'd be really grateful as will my bed-bound elderly DM, although she's fine in her bed with the electric blanket on!

Does it have an external filling loop, often a SS flexi hose, sometimes hard-piped? Could you post another photo showing the WHOLE pipework below?

Anything like these two valves on yours? With perhaps a hose hanging from one of them?

I have that - page 7 says 'Your installer should have informed you where to find the filling system and instructed you in its use."

Ok - will do so.

If you look under the boiler on the right hand side just behind that thing with the green light you'll probably see a blue plastic lever, this is the keyless filling loop, all you need to do is pull the lever down to start filling the system. If you don't have this then you'll have to follow the instructions posted above with regards using an external filling loop.

FYI, you wouldn't normally expect the pressure to fall that low on a new boiler installed in October, you may have a leak somewhere.

Surely such a new boiler would not have an external loop?

Here's the pics.  The boiler is very high up with pipework extending down under the floor of the cupboard!

I'll have another wee look for the blue plastic lever, thanks.

No blue lever, however I've found a black key-like thing hiding behind all that looped piping at the bottom. Sorry it's blurred, it was difficult to get my phone in there as the piping doesn't move.  If you look at the third picture above it's behind the loop.

Would that be the holy grail?

It looks like the installer has moved the external filling loop further down to just above the filter, in your third pic. That black key should open the cold water feed and fill the boiler.

This should be easier than it is!  The old boiler had a lever which re-pressurised and was obvious. I won't touch the black key, we'll just have to wait until an engineer calls me. 

Thanks for all the suggestions so far, I really appreciate it.

It is easy. The boiler doesn't come with an attached, keyless filling loop as standard so rather than fit one your installer has fitted an external filling loop instead. The instructions on page 7 of the operating instructions show exactly what you need to do in this instance, just turn the key. However, if you're not comfortable doing it then that's fine also.

Personally I'd more concerned as to why it's dropped pressure so much.
