Baxi boiler 'clicking'

[Skier]

I have a baxi boiler and when it ignites you can here a clicking noise like a piezio spark thing you fink on a cooker. I have noticed that it rapidly clicks away about 5-10 times in a couple of seconds now.

Does it need cleaning?

Am I wrong and its a relay in the circuit thats not clicking over properly?

Ove r the years they have made quite a few different models a model name and number and/or GC number would help here.
