Hi, I've very recently had the above boiler fitted. Everything worked fine for the first day. Woke up the next morning to find that the pressure gauge was showing zero. Various lights were flashing on the front of the boiler. The manual says that this is a "faulty primary circuit (no water or absence of water)". I opened the valves of the filling loop and re-pressured it to just over 1. After a day or so it was back down to zero. There are no obvious leaks around the boiler or any of the radiators. The firm who installed the boiler are coming back tomorrow to sort it out, although does anyone know why I this keeps happening?
Many thanks in advance.
