Money and time. I recall one clinical machine that was still not operational I think something like 15 months after unintentional quench. That’s expensive real estate to be sitting idle.
15 months is exceptionally long. With a decent support contract, it can all be sorted out in a few weeks.
In theory it can, but depends a bit of damage and the state of your support . I suspect that one was due to arguing about the latter than the former.
