Patience . . .
jdrof,
Mine was delivered DOA ... I stuck it out. I now have a machine that works. And I'm confident it will keep working. I'm also of the opinion that if you fix the problems with the current machine you know what problems to foresee in the future. If you get a new machine, who knows what problems you'll have and you "could" be at square one again.
Just my opinion.

Face each day with both eyes open wide, and try to give, don't keep it all inside"
