I have an Ariston EuroCombi boiler. Recently it has started to cut out and
will not restart. I believe the problem to be a faulty Air Pressure Switch
(APS). Taking it out and reseating the contacts has cured the fault several
times now.

Is replacing the APS a straightforward operation or do I need to calibrate
it etc?

Thanks for any help,

Peter

Are you saying that you have poor connections on the 1/4" spade
connectors

best to actually test it rather than replace it for the sake of doing
so, I've explained how to do this in numerous posts in the past

Plug and play ... so to speak

it etc?

No, keep your grubby paws away from the calibrating screw, it will be
set (one hopes) correctly for your boiler


Thanks for any help,
