Think I need to replace the APS on Eurocombi SX20. Is this something anyone can do or does it require specialised knowledge. I have the replacement and it looks like a simple case of detaching pipes from old and replacing on new etc but I don't want to attempt it if there is a high risk. At the mo pilot light goes off and on intermittently but at least it does sometimes go on.
