Moved house and have my first ever gas boiler which has (of course) stopped working.
It's an old Baxi Solo 3 and it had been working fine until this week. Now it fires up - power/fan/pilot/burner all on, but after about 10-15 minutes, the burner goes out and the rest of the lights stay on.
Replaced the pump to no avail.
Any advice before I have to go and sort a new boiler install?
