Puma 80 low pressure light on despite plenty in the system

[Johnnyboy68]

I have a Potterton Puma 80 boiler and the low pressure system light is constantly on.
I have recharged the system to well above the minimum and have bled all of the radiators just in case and the light will not go out.
The boiler will now not fire for either central heating or hot water and the pilot light is on.
Any advice would be appreciated.
Thanks in advance
John

thanks for your response.
Why is it an adventure? is it located in a difficult place?

You will probably find that if you pressurise to 1.8 bar that it will be working tomorrow morning.

Changing the LP switch is fairly easy for anyone with suitable experience.

i managed to locate the switch, gave it a few taps and it reset itself over night.
Thanks to everyone for their input, it is much appreciated!
