Potterton Puma 100e Low Pressure?

I have replaced the safety valve and thermostat on my boiler, when the system pressurises to about 1bar the low pressure light comes on and the boiler cuts out. if you release a fraction of water or wait approx. 10 mins (sometimes) the boiler resets and fires again

The low pressure gauge keeps dropping down to below 1 bar.

it sound like you have either a blocked low pressure switch, or the wires on the switch have been put onto the wrong connections.
