Clicking noise on Worcester Bosch Greenstar 30si boiler

[PS Sue]

Wondering if anyone can help me out please?

I have the above boiler, just under 6 years old.

When the burner fires up (either to heat central heating or when turning the hot tap on) there is a loud clicking/vibrating noise that lasts for about 5/6 seconds......I've just had a new circuit board fitted and a service....I've never noticed this noise before. The chap who fitted the circuit board and serviced it said it was "normal" when the burner fires up?

Thanks in advance.

If its a sort of juddering noise, it'll be the diverter motor. I've got the same boiler and mines done this for years, its normal.

But it's only just started making this noise since it's had work done on it. I've never heard it before at all.

I've heard that before

Phoned Worcester this morning and they say the noise it's making ISN'T normal and it's likely to be a faulty circuit board that's been fitted, so made a call to the plumber who was surprised but is going to order another one and arrange to change them over.
