Need some advice from the forum members. couple days ago my WISE stopped working. here are the symptoms: - powers on - the WISE goes into starting sequence, but the tension head doesn't move. if i try to help it along by hand, it'd go maybe half way and then go back. - then it shows an error, usually 5, but sometimes 3. before this happens, it was acting up a little already, sometimes the tensioner won't start. i sent a email to wise and they haven't responded. either they are slow or they are off due to holidays. what are my choices? 1. open it up? but i think that will trigger an error because they have some sort of safeguard? 2. send it back. i am still waiting for the reply. what kind of repair cost should i expect? 3. buy a new one? 4. buy new machine all together? 5. go back to crank most of you will say 4. but unfortunately that's gonna cost too much. i won't do 3 unless the cost of repair is so much that i might as well get a brand new one.
