Hi my name is Brian.
0.4 bar will not be enough pressure to activate the pressure switch you need to find the filling loop which is normally a silver braided flexible hose about 30cm long this is connected from a mains water pipe to one off the 22mm boiler pipes. its usually fitted close to the boiler. this loop has 2 valves once you have found it turn the valves on slowly and increase the pressure to 1.2 bar then turn them off again.
