Baxi 105e Combi Lights Flashing No Hot Water

I was called by a customer who regularly calls me because his Baxi 105e Combi boiler stops working. The boiler is installed in the loft and contrary to building regulations does not have a means of fixed access which makes it impossible for the elderly gentleman to attend to the boiler.

The boiler had gone into a fault mode and one of the LED's on the front panel was flashing. The symbol above the flashing led was an upside triangle which is the pump symbol. In the manual it suggests there is an issue with circulation, which there was. The pressure gauge was showing zero pressure and hence there was not enough water in the system.

I opened the filling loop, filling the system to 1.5 bar before switching the boiler off an on to reset it. The boiler ran and I topped up the water as necessary due to the air being expelled through the automatic air vent. Once again the boiler was working well.
