Powermax 155 - Vibrating Noise ?

[simonp01]

Hi
I have a powermax 155 boiler.

When it kicks-in, there is the usual click, and for around 10 seconds there is a vibrating noice from the flue-pipes that then goes away.

I cannot see any "obvious" cause, (I was thinking that a fan might be causing it as it "spun-up".

COuld it be a valve vibrating as its turning ?
If so, I can't see it.

Pumps all seem to be ok....

Any advice welcome....

could be a few things BUT its a corgi job.
get a corgi engineer who is familiar with your boiler a lot of engineers will not work on these boilers,so be patient.
potterton do fixed price repairs and on this boiler it is money very well spent.

It's possibly the gas valve, out of calibration.
