Noisy boiler after leak sealer

[eejaybee]

ARISTON A/23 combi
making vibrating noise on start up and when automaticallyswtching on and off in heating mode no noise when actually fired up
noise will also occur when hot water demanded in heatin mode as extra gas is supplied
ANYBODY GOT ANY IDEAS ONLY STARTED AFTER LEAK SEALER ADDED CAN I FLUSH THIS OUT EFFECTIVELY

i personally wouldnt add leak sealer to a combi. there are far too many little nooks and crannies for the leak sealer to get into. thats why sludge tends to B****r em up.

some peeps may have done it tho, thats just my opinion.
hope you get it sorted.
