Puma Potterton 80 low pressure

[jbw1]

Hi.

Please could you advise.

Moved into house 6 months ago. House is around 10 years old - Puma Potterton 80 boiler is around that age.
Pilot light is there - but not firing up on demand from heating or hot water.
Low pressure red LED light is on.
Have turned on top up tap to fill up - but no sound of pressure. Turned off straight away.
Red LED light did not turn off.
Pressure gauge is full of water and leaking.
Red needle is on 2.5
Black needle is on 3.5


I'm hoping I can hold off buying a new boiler??
Does this sound repairable?
Thanks

If the pressure is 3.5 then its too high and as you said already caused some leaking! Should be about 1.7 bar cold.

The low pressure switch is either failed or blocked.

Probably by tomorrow it will have sorted itself out.

If not then it needs a new LP switch. Probably about £24. needs draining boiler to fit !
