My powermax 155x boilers has been working fine but couple of days ago the pressure dropped to under 1 and lockout light came on. I filled pressure back up but when i try restarting ( leaving off for 10 secs) the green boiler light wont stay on, it comes on for about 3 secs and goes off. Any ideas ?

Is that something i could do or leave to the heating engineer ?

sounds like the low water pressure switch needs either cleaned or replaced
