I only have the user manual for my Ariston micro Genus HE 28 MFFI boiler, can you locate a SERVICE manual for me? The display gives a t error message 05 , when the pilot goes out and the boiler shuts down . the user book refers to E 04 E05 etc but gives no detail.

look on ebay you can buy a disc with all the manuals on for around £5, look for m.edwards1201 as a seller he throws in a extra cd with plumbing course on
