boiler starts with a bang

[dela]

Hi folks, I have a potterton combi 80e ....yeah i know a should have put it out of its misery a long time as ago.
Anyway after replacing the pcb a couple of weeks ago i have noticed the thing seems to letting too much gas out or taking too long to ignite it. Thus it is starting with a bit of a bang...... if it was my Mbike i would say too much air getting in at combustion....
all help greatly appriciated

Without getting the books out it could be a faulty slow ignition problem with the gas valve AND/OR its overdue a service.

You need someone out to it either way
