We consistently get the CO line volume due to excessive current in addition to expansion cabinets staying in "enabling". Yes, there are replacement parts and work arounds for both but each requires additional labor and cost that can't be recovered.
We have been cranking out 2 a day since the system was released (yes big roll out for us, about 400 to date) and we have at least 2-3 each week that exhibit these issues. I watch and listen to PM's and Supply waste HOURS on the line with tech support for known issues and out of box failures. We've had systems "bad" in the field and work fine in the lab. I love that one, spend 2 hours troubleshooting, send an overnight replacement, receive the bad unit, and can not duplicate the problem. Talk about a profit vacuum.
