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.
it is a fairly straight forward job for somebody that has been trained. there are things that could go wrong is it the correct aps switching at the correct pressures?is the diagnosis correct?I must advice to get a corgi boiler reg person in
