FERROLI OPTIMA 700

[PPP666]

can someone please confirm how is it is to replace the air pressure switch on a FERROLI OPTIMA 700 boiler.
My boiler has been working with no problems until this weekend, the pilot light is on but it does not ignite when you put the hot water on or the CH, i have been told it may be the air pressure switch

The air pressure switch is inside the combustion chamber cover.I would suggest you get it checked by a pro.May not be aps but another component failure ie fan faulty.These boilers are 12/15 yrs old and you shold consider replacing as repairs can be costly.Good luck.

The fan is still working so assume its just the APS
