Hi .I am assuming that it is a Combi boiler? The only wat to drop the pressure would be to release some water . this can be done by opening a radiator bleed valve and letting water come out till the pressure drops . there a few things it could be for no hot water , but need some info whilst you are at the boiler, thanks. Toby
Is the pressure gauge reading 3 bar?
No , these things can take a while to do properly. I am available this when toon
Ok , what time roughly
Hello . is your heating working ?
No it isnt . still the same
Ok . can we try to pressurise the boiler , is fill it up bwith water till it gets to @1.2 bar
Yes here .
Are you there?
and next to the boiler
how do I do that...
Ok . can you see a flexible hose under the boiler anywhere?
Ok . it will have a tap on it , there may be one or may be 2 .open the tap/taps till pressure. Goes up to 1.2 then turn them off
ok ..trying it
oops it in 2 now
did I increase too much?\
That's ok. Reset the boiler if there is a reset button . if not turn the power off for a few seconds then back on
Ok , then try hot water, but listen to the boiler . is it trying to start, can you hear the fan running , can you hear sparking,is trying to light?
no nothing ..
its still the same
Ok . do you have a fault codevbonbthe boiler or any LEDs lit?
the first on is blinking green
if i open the tap the first and the last are blinking
Ok . these might give an indication as to where they fault lies, but first I will need the model if the boiler , I know it a biasi
and the manual says - lack of ignition
no ignition signal from the full seq ignition device
manual has three model - M96.24SM/c
Ok . ignition will not happen if the fan isn't running.
how to turn it on :(
If its not running then it is faulty and needs replacing.are you sure you can't hear the fan?
I can hear some noise everytime I OPEN THE TAP
oops sorry for the caps
Do you feel comfortable taking the front case off?
but i cant see any gas / light heating through the glass opening
If the fan isn't running it won't light. The fan runs, the air pressure switch makes , then gas valve opens , then sparks , then ignition
oh ok.. let me try opening the front case
Are you comfortable taking off the front cover?
hiya .. I have taken it off
Ok . when you have cover off open tap , be carefully not to touch electrical connection , and feel the pump.is it running?
Also turn on the heating and check pump
as soon as I open the tap I hear a click and then a right light
and realising our heating is not also working
Keep heating on , reset the boiler put your hand on the pumpn. Is it running?
Should feel vibration
one silly question - which is the pump
Its got a round face , bottom right hand side.
yes it is vibrating
Ok . reset again . thevfan is at top left, looks like a stubby cylinder . is there any sound coming from this?
ok let me try
i can feel the pump slightly vibrate
but no fan
just hear a small rumbling noise
Ok .it seems like the fan house failed. It will need replacing . can you do this yourself?
I can try .. but with what should i replace with
To be honest , it is probably something a boiler guy should do unless you feel compfident
Fans cost around £140 , not cheap.
umm ..let me better not try hen
Ok , sorry that its not an easy fix. Would you mind rating me?

have a good day
All the best . , Toby
