It's okey now they fixed it. But the problem it had was it could not find the home position. Just kept on rotating and no Zero could be found. We did what we could. cleaned it out checked the contacts in the box etc. But when it came back it was a major upgrade and rebuild. We havent had any problems sence. But one never knows.. One day we could turn it on and nothing happens. I'm sure it's to do with all the moisture etc. from the coolant getting inside. It would be nice to have options though.....
