No pressure in combination boiler

I have just moved into a new house. The Worcester combi is only 3 yrs old and is playing up. There is no pressure. & no hot water. Is there anything I can do before calling somebody to look at it? I have noticed there was a slight leak in the radiators in the lounge. Thanks

When you say no pressure, do you mean on the dial on the boiler?0

If there is no pressure the boiler will not work. (and that is a good thing).
There will be a filling loop at or near the boiler to re-pressurise it, an easy thing to do once you have been shown.
If you can find it and do it, set the pressure at about 1 Barr (1 on the dial)I used to be indecisive but now I am not sure.0 -
After I bleed my radiators (I too have a combi boiler) I have to increase the pressure back up - I have a small flexible hose that is attached to the water outlet and then the inlet of the boiler (just under the control panel) this then increases the water pressure.
Your best bet is to contact the help line number and ask for their technical help section.0 -
The lack of hot water won't be solved by increasing the pressure though.
Does the boiler sound like it's firing up when the hot water tap is turned on?0 -

If there is no pressure in the boiler it will not light and there will be no hot water.I used to be indecisive but now I am not sure.0 -

Insufficient pressure activates the shutdown of the PCB, no fan, no pump, no burner,.............NO CH or HW.0

Yes, I meant zero on the dial on the boiler. I thought I have posted this on the in my home forum, guess got a bit mixed up!!0 -
Yes. But.waynehayes wrote: »Isn't the hot water supply seperate to the closed heating system?
The hot water supply is not heated directly by the boiler - it is heated indirectly by a heat exchanger from the closed heating system. If I understand it correctly.Hi, we’ve had to remove your signature. If you’re not sure why please read the forum rules or email the forum team if you’re still unsure - MSE ForumTeam0
