baxi

[carlo]

i have a problem with a baxi back boiler,with an electronic pilot.when it tries to light it makes an extremely loud buzzing noise and seems to get worse the longer it's on,once it's lit its fine and it doesn't do it all the time.I have replaced the petenchiometer,it's still the same,i have serviced it and can find nothing wrong.I have never come across anything like this neither has anyone i have spoken to.this buzzing really rattles the whole house apparently.any ideas would be very much appreciated.thanks CARLO.

After questioning my tenants further it turns out it isn't the pilot trying to light,it is already lit,it is the burner.I wonder if it could be a problem with the flue or perhaps the room vent as it only starts after about two hours of running fine?
