Worcester 25si/30si no heat or hot water

[russpb]

I recently bled my radiators and then noticed the water pressure was low so I put some more in using the supplied key and following the instructions in the manual increased the pressure to 1.5 bar. The boiler will not stay on to produce any hot water or heat. When I press and hold the reset key sometimes, not always , it fires up for about 30 seconds and then goes off.I also poured warm water on the condensate pipe in case it was frozen from yesterdays frost. I do not have a green flame light on, the blue light is on continually. The boiler is about 18 months old. Does anyone have any suggestions or should I contact the manufacturers? Many thanks.

All you have done is bleed them not drained down or anything am i correct, after u have run the water for a while does the boiler lockout and the blue light flash?

If it does look in the instruction manuel and it will tell u what the flash means and a probable error

Check external controls first

Shouldnt affect the water though as long as power is on as is suggested by the blue power indicater light being on. Other than external what u reckon Tamz

The blue light is steady and doesn't flash at all.

 

[russpb]

What do you mean by 'check external controls'?

Eg timer room stat for heating

Thanks for your replies, I put the timer on constant and tried the temperature at different settings but still no joy.

The blue light only confirms there is power to the PL of the boiler.
If it is doing nothing at all it is either the fuse on the board or a faulty board.
You need someone to look at this.

Thanks guys, as it is only 18 months old I read that worcester/bosch will fix it.

They will.
