No Hot Water After Draining Down

A customer of mine was carrying out some renovations to his house and had dug up some of the floor screed exposing some pipes. He accidentally holed one of the pipes causing a leak. He managed to repair the leak and re-fill the heating system. Unfortunately the next day he had no hot water when he went to have a shower.

When I arrived the Main HE boiler had locked out due to overheating as indicated by the LED's (flashing,off,on). The pump sounded as if the system was full of air and the automatic air vent was leaking. I bunged the system and replaced the automatic air vent. I also bled all of the radiators two of which were full of air. I then ran the hot water making sure the system was circulating before running the central heating system and making sure that it was all working as it should be.
