I have checked my oil level which is fine. no lockout light on but my pressure is reading 0.5 bars I have read instructions online about how to repressurise but can't find the flexi to do it I have found a red valve that reduces the pressure but can find no way to increase it

Hi if you can find a small 15mm pipe coming in to the boiler follow it and there should be the start of the filling loop.

Hi Brian, I've found a pipe that has a black plastic valve on one end, There doesn't seem to be a valve on the other end though. It is already attached at both ends. Turning the black plastic valve does nothing. Can I take a few pictures and upload them? Maybe you can guide me a bit better then?
Plumber: Brian, Plumber replied 2 years ago

yes please do

Customer reply replied 2 years ago
ok, so I open the valve on each end of that pipe, until the pressure is at 1bar?
Plumber: Brian, Plumber replied 2 years ago

yes around 1 bar or 1.1

Customer reply replied 2 years ago
Ok, so done that, and the pressure has risen nicely, seems to be holding but, boiler still hasn't fired. :(
Customer reply replied 2 years ago
wait, i'm telling lies. It has fired. So fingers crossed it stays on. I had managed to get it to fire a couple of times this evening while the pressure was still low, it would stay on for about a minute and then shut down. Hopefully with the pressure back up now it should stay on?
Customer reply replied 2 years ago
No. It went back off again after about a minute...
Plumber: Brian, Plumber replied 2 years ago

But you say there is no lock out light on the burner?

Ask Your Own UK Plumbing Question
Customer reply replied 2 years ago
nope. I've tried the boiler reset and flue reset buttons too but nothing.
Plumber: Brian, Plumber replied 2 years ago

Ok so you have 1 bar or over water pressure. you are calling for heat or hot water You left the valve that you tried earlier in the same place you found it and you definitely have no Red lock out light on the burner.

Ask Your Own UK Plumbing Question
Customer reply replied 2 years ago
all correct. The only time I seem to have been able to get the boiler to start is when I actually draw water from the hot water tap, the boiler fires but only for a very short while (although this doesn't happen everytime, it's not working now...
Plumber: Brian, Plumber replied 2 years ago

Then this sounds like the diverter valve is failing when you turn the heating on and turn the dial for hot water to off can you hear the diverter motor running

Ask Your Own UK Plumbing Question
Customer reply replied 2 years ago
not while the boiler isn't fired no. Is that the silver and black cylindrical bosch piece in picture ending 415?
Plumber: Brian, Plumber replied 2 years ago

Nope its picture 405 plastic box with writing on it

haha the one that says "Diverter Valve" .... Anything I can do to maybe fix it?
Plumber: Brian, Plumber replied 2 years ago

Yes I didnt want to insult.

on top there is a slide just try moving that across when you have heating and hot water switched on

Ask Your Own UK Plumbing Question
Customer reply replied 2 years ago
ok so i moved it across to the left, it also went down into the box and clicked into place. both did nothing... when in its original position it is quite loose and able to jiggle about a little bit?
Customer reply replied 2 years ago
when i slid it across another lever on the side moved from the A position towards B
Plumber: Brian, Plumber replied 2 years ago

ok so its not seized. Well im sorry but I dont think there is a lot you can do without testing for power through the motorised valve. its often the motor that goes on these and it stops the valve moving. but i cant say for sure without looking and testing really.
