@judgedread @Scubbie several people have solved the problems with those soft serve machines, and the company takes them to court, with the full backing of McDonalds, to make sure they can't be fixed... If i had any faith that any of this system was rooted in decent people trying to do the right thing, i would be appalled that this behavior is even remotely legal, but, i don't, so i expect it.
Solution: Either force the ice cream machine company to remove the temp bricking 'feature' or find a new vendor.
All relevant systems are out of patent, MickyDs has been doing soft serve ice cream for over forty years.
