Baxi Boiler starting up with a big bang?

[golfegghead]

Hi all,
Thanks for previous great advice with my baxi boiler in understanding my PCP problem etc prior to hiring a plumber. We hired a brilliant plumber and have had a new PCP and gas valve fitted and everything works like a dream again. Well, except one thing that now bothers me, when the boiler lights up every 5 mins or so to reheat the water etc it sounds like a mini explosion in the boiler. It is much noisier than it used to be i.e we never noticed the light up phase prior to new PCP or gas valve being fitted. It is concealed within a wardrobe to an external wall of a bedroom upstairs, but it is so loud it wakes everyone up in the morning. Is this normal or is there something that can be adjusted to quieten the noise at point of ignition? The boiler seems to click three of four times, probably some start up phase, or is it trying to start? But when it does it can make you jump as it seems a very fierce bang or build up of gas? Sorry to ask, but I am still waiting for my plumber to come back one, with the bill so I can pay the amount quoted and two I can have some kind of answer armed ready.
Thanks for any tips
Steve

Explosive ignition, needs seeing to straight away, have him check it before payment.

Which baxi is this?

If it has permanent pilot i would imagine it needs pilot flame adjusting / cleaning.

Evidently everyone else knows, but whats a "PCP" ?

Sorry if I am a bit slow tonight but had a busy day!

Some sort of drugs I think Tony.

Hi,
We have a Baxi Solo 3 PFL Range boiler.
I think, I may need to check tomorrow that the pilot light stays on when the boiler is in operation.
I will chase the plumber again tomorrow and chase them up, as my wife is concerned about the noise the bang makes as it ignites. I must admit it is not what I expected. I hope it can be adjusted down or cleaned as mentioned.

Golfegghead, what was the outcome of this, my baxi solo 2 has just started doing the same as it seems happened to yours.


Thanks

That was over two years ago.

As you could deduce the boiler may need setting up correctly by an RGI.

When did you last have yours serviced?

funny enough was serviced a week ago and almost immediately started doing this (never did it before). they are coming back on wednesday but does leave you wondering with the thud will it last till then! hence wanting to know if the root cause was something that they will easily put right and i shouldnt worry.

thanks
