BIASI M90 combi probs

[kevboy]

Hi folks
I have a two year old Biasi Riva M90E.32.
Recently theres been a change in its ignition. It seams to take 10 time as long to ignite following the demand either hot water or C.H.
fans and pump all working.
No changes to gas supply or pressure.
No need to press reset switch

Is this the first sign that something is about to fail.

thanks

sounds like it needs a service
