Thoroughly Modern Minnie's new boiler

It's probably a pressure thing. Is there a pressure dial, and is the dial at zero? If so, there's probably some tap things somewhere that need opening to get the pressure up (ours had two plastic taps underneath that both needed opening half a turn until the pressure was up to 10 or so). You don't need a plumber back unless you don't know how to do it. If you do get them back, make sure they show you what to do as it might happen again.

hm indeed. The control on the wall has four settings: off, automatic, once, continuous.

I had switched it to off after testing it when they left. I switched it on to continuous today and nothing happened. :hmm:

Does it have 2 sets of those controls? Non combi boilers do. 1 for the heating and one for the hot water.

Have you turned the heating to continuous but the room stat says you're already hot enough?

It was only put in and filled last week. Should they 'leak' that fast? :eek:
 
Dunno. Our pressure went down a few months after it was first installed, but then it happened again several times in a few weeks, then it was fine for months until we left. :confused:
 
This is what the controls look like

Taken last week, so obviously those two dials aren't in those positions, they're both past 12 o'clock.

A digital display is saying 22c (there may be an F in front of the 22) and it's flashing. It doesn't seem to stay on though

It only has one control panel on the wall. It's Honeywell control panel.

I'm going to have to go back tomorrow so will take more photos of the settings the boiler and control panel are on.

There's manuals there but there's about 4 of them and I don't like manuals :D
 
What does the little dial at the right say? Is it pointing to the green bit?

If it's below the green mark you need to pressurise the system or it won't work.

There will only be one control panel. Mine is a honeywell branded control and has 2 slider bits for Off, once, daily, continuous. One of these controls the heating and one controls the hot water.

Why you would need a separate control for the hot water on a combi I'm not sure but I've never seen a contol panel with heating only on it.
 
I'm sure the panel's almost the same as this except it doesn't have buttons on both sides of the digital display, only the right-hand side

I've not investigated that dial. I left it where it was. I didn't want to fiddle with anything as it worked last week

hm, page 8 talks about pressure and it does say in the notes that "if the pressure falls below 0.3 bar, the unit switches off. The error message F22 appears in the display. Fill the system up with water before you start up the appliance again"

How do I fill the system up with water? :confused::hmm:

You need an engineer to refill it and reset the pressure.
 
There should be a valve on one of the pipes which feeds into the boiler. To top it up you open that value, the pressure should then go up and you turn it off when the pressure is where it should be.

Does the manual indicate which of the pipes is the one for filling it up?
 
I did this at my house at uni! It's easy! There should be a bendy hose with a small tap on it somewhere...

yeah, mine has one although because it's such an expensive piece of kit I don't like to mess with it.

Thats fair enough, however I was freezing in January!! My less technical minded housemates were trying to have a shower in a kettle or something stupid ike that.... Sod waiting for the plumber, to the internets, you can find out anything!!!
 
Ooh, now you're going to be lovely and toasty in the winter Minnie! :cool: well, not cool, rather warm in fact, y'know what I mean.

Thanks for the tip about Vaillants being the ones to go for, I'm going to have to get new central heating in the next year or so, so it's good to know.

One thing I'm uncertain about though is that I vaguely recall having a quick chat with the engineer who did the annual has safety certificate, and if mentioned something about the pipes. The existing ones actually go through a wall, well through the terracotta skirting tiles and he said they wouldn't be able to do that anymore, so I'm not quite sure how they'd have to do it now.
 
It looks like the dial on the bottom right of the panel is for pressure - the one that looks like something you'd see on a car dashboard, not the ones you can turn to different settings yourself. And it looks like the pressure has gone too low.

Get the engineer back to sort it out, and get them to show you what to do. It's very easy, but not if you're not sure what/where everything is.
 
BTW: I've just received September's Which? magazine and they have a boiler report.

Vaillant and Worcester come top. My one looks like it's a best buy :eek:
 
From what I can tell, you have one of these.

On the right of that page, there's a Servicing and Installation guide. Section 5.4.2 of that has info on how to use the built-in filling loop.
It's not amazingly clear but there appear to be two valves under the boiler that have to be turned on to fill, and then off again afterwards.

If in doubt, ring the plumber and ask them what to do, they may be able to explain over the phone.

Blimey, I'm not doing that :eek:

Think I'll have to call an engineer :D

Calll the guys that installed it...they should have left it on and in working order. Be flexible about when they can come and don't let them charge you as it won't be a big job. 2 mins work, literally.

It was working when they left. Now it isn't :D
 
I have to repressurise my bloody boiler ever other bloody day in the winter :mad: Have to unscrew the wood panel, stick my arm down the 'ole and open a tap until the needle goes back over 1 (I think) :mad:
