take the pipe off below boiler and pour water down it to see if it runs free.
otherwise call w/b as its under warranty.
the other possibility is a gas supply fault/regulator - but it worked after clearing the condense trap !
& yes, done 3 condenses this week with blockage from the 21mm pipe joint into drain, stops boiler dead and last one was on 3rd floor with pipe into 4'' soil stack % 2 into kitchen waste pipe.
Working my cohuners off in the back room!
boiler making vibrating noise like kettle|boiler making whistling noise boiler making humming noise boiler making load rumbling noise boiler making gurgling noise.
