Excellent!  Congratulations.  You have just diagnosed the problem.  Should have
thought of that myself.  Fair warning, though -- it will be back.  Maybe next
week, maybe in five years.  The carbon track is worn out where the wiper bears
on it.  Long term cure is to slightly alter the relationship btw the wiper and
the resistor pack (says "Bournes" on it, even Bosch uses American Engineering
sometimes) so the wiper bears on a new section of track.  That should give you
the moral equivalent of a new one, unless the wiper itself is worn out
(unlikely).  In the meantime you could secure the AFM cover with a TyRap or
similar so you can get back in and spray when necessary.

ps -- Do you have to be Authorized to be an HP customer?  Snooty bunch...
