AquaPure 1400 error message

I have an AquaPure Apure 1400 that is giving a 170 error message. Does anyone know how to trouble shoot the circuit board?

The AquaPure manual (here: http://pool9.net/aquapure-man/) id's that fault as "dealer only".

I found what appears to be an Aqua-Pure test guide at Inyopools, here: http://pool9.net/aquapure-sman/


Good luck!
