Think I found the thread.
Certainly one or two not enchanted with DFs generally. Not unusual.
My experience of the DF64s is probably different due to having upgraded the portafilter forks, fitting an anit-popcorn bean feeder and Gorilla Gear burrs. Apart from all that I left it completely untouched 😃😄😁
Jake if you can find the avatar of the posters with blown engines I would be grateful. Or date/time of posting. I’ve had a look but TBH Discord gives me a headache. Old brain doesn’t work with a hipster app maybe?
Reading it again (or trying to), it sounds more like electronics issues rather than blown motors.
Either way, interested.
