XXXXX XXXXX : Do you have a silver flexible pipe attached to the pipework under the boiler?
Customer:

Hello Andrew, yes there is one. PS sorry, I said that the marker is at 10 - it's actually at 2.

XXXXX XXXXX : Does it have a valve at each end?
Customer:

yes it does

XXXXX XXXXX : Ok, open one by using the lever or a screwdriver so the slot or handle is in line with the pipe
Customer:

can i send you a photo of it? I am not quite sure what to do

XXXXX XXXXX : Of course,, try attaching it
Customer:

Full Size Image

XXXXX XXXXX : Ok, that one is off as the slot of the valve is across the pipe direction
XXXXX XXXXX : do you have one the other end also?
Customer:

it's quite hard to access

Customer:

I have to pull the pipe through the hole in the cupboard

XXXXX XXXXX : Can you get a screwdriver in the slot?
Customer:

yes i can

Customer:

I just unscrewed it a little bit and water started to appear

XXXXX XXXXX : Does it look like the one in the picture?
Customer:

yes

XXXXX XXXXX : That sounds like a non return valve
XXXXX XXXXX : what happens if you turn the one in the picture?
Customer:

the same happens - a bit of water appears

XXXXX XXXXX : ok, can you leave one open and turn the other on slowly?
XXXXX XXXXX : water should fill the sytem
XXXXX XXXXX : take it back up to 1.5bar and then turn them both off again
Customer:

the bar is slowly increasing

XXXXX XXXXX : good, leave it to do it slowly as I do not trust the valves if they drip
XXXXX XXXXX : turn off at 1.5 bar
Customer:

okay

Customer:

going well so far!

Customer:

it's at 1.9

XXXXX XXXXX : Turn off now!
XXXXX XXXXX : Just up to 1.5bar
Customer:

i have turned them off

XXXXX XXXXX : ok, your boiler should work now
Customer:

i can hear trying to do something, but the flame isn't igniting

XXXXX XXXXX : do you need to reset the boiler?
Customer:

how do i do that?

Customer:

just turn it off at the mains?

XXXXX XXXXX : You should have knob with a reset position or a reset button
XXXXX XXXXX : press or turn and hold for at least 6 seconds and release
Customer:

there's a red button. I've tried a couple of times but with no luck

XXXXX XXXXX : Any flashing lights on the boiler?
XXXXX XXXXX : what is the make and model?
Customer:

there is a green light indicating it's switched on

Customer:

Its a Savio Caldaie 24S

XXXXX XXXXX : What happens when you run the hot tap?
Customer:

I can hear something click, the boiler hums, but no flame.

XXXXX XXXXX : Can you confirm the gas is still on?
Customer:

how do i do that?

XXXXX XXXXX : Has it been turned off that you know of?
Customer:

not that i know of. It was working fine yesterday.

XXXXX XXXXX : you have got the pressure back up, well done.
XXXXX XXXXX : i do not know what else is wrong?
XXXXX XXXXX : you may have to get someone to look at the other problem
Customer:

okay. thanks for your help.

XXXXX XXXXX : No problem
