Iontopheresis broke?

[Englishman]

I've got an Idrostar. I've been doing sessions all week (today is my 6th) and suddenly, when I went to start my session the current isn't buding from 0 even though I'm moving it all the way up? I've changed the batteries and everything... Any suggestions?

Sounds like it's not making a connection. Is it possible that the wire leads are not connected properly? Meaning maybe the connections on either the male or female ends of the wire might be broken internally.
