Potterton Performa 28, flashing red light low pressure or pump fault light?
Pump failure, but replaced with new pump which runs but the system would not fire up and just flashes at the 60 degrees llight. Previously the 30 & 40 degrees lights would illuminate to begin with but dont come on at all now.
Problems seems to be from lack of ignition, gas supply to the property not a problem.
