We have a Body Train treadmill that was working fine. Now it's stuck in full incline with a E13 error which according to the manual the signal wire needs changing. All wires look okay no sign of breaks. There is also no schematics diagram to say which is the signal wire and cannot find anything on Google.
Thought would reach out on a forum see if anyone had a similar issue or is it a case of needing a new machine rather than a simple fix.
