Ideal Icos HE 15 Problem

[AST81]

Hi, going back to the original query of noises. I had a blocked condense line firstly going into the drain on a swept T joint. Then the L F came back on after a while and still noises before hand. Took bottom cover off, far back right hand side take screw out and slide panel out to the right. Underneath you can see a black trap going to your white plastic drain. Unscrew pipe fitting, undo 2 screws. Twist and pull down and a little wiggle if stuck. No hitting it as only plastic. This is the S bend which will be full of grit from the burning process. Bash out in bin and wash out. Be careful as 'O' ring on top (make sure in place when it's put back). The trombone noise can only be the air and blocked water in the bottom of the boiler. Mine is now quiet and working great. PS please switch of boiler before working on it.

THIS WORKS WAS COMPLETELY BLOCKED ESSEXFELL LEGEND!!!!
