24i pressure topped up but not staying on.

[Jill Farquhar]

My 24i boiler had dropped pressure which I topped up with the topping up hose.
Now the pressure is about 1.5. But when I start it up it ignites then slows down and stops again.Does this off and on for a few.mins then stops completely with blue light and red fault lights flashing.
I've bled a radiator and topped up pressure again..but still not working.
Please help if you can.
About 13 years old or so been regularly maintained.
My area seems to have low pressured water if that helps?

I am guessing its a worcester 24i ? can you pinpoint the fault from this chart ?

 

[Jill Farquhar]

Might be Number 4 in the chart.

Might be air as you have just topped up the boiler, there is a vent inside the casing but I dont advise you to take the cover off.

Hmm...do you think I need a plumber?I'd rather sort it if I can as I'm broke

My advice would be to turn off the boiler and wait until you have the money to have it fixed.

All ok before the pressure loss?

The pressure dropped to zero and it stopped working yes.
