Wahoo Kickr Run Error Code 62

Anyone have experience with the Wahoo shutting down and showing E62? I've been emailing Wahoo for weeks and they say no one has ever reported this before and they have no idea what the error code means. Beyond disappointed in the level of customer service after dropping over $6,000 on a treadmill. At 7:00 pace it shuts down less than 30 seconds into a run - this thing is unusable at this point. And yes - I have a dedicated 15 amp circuit for the treadmill - nothing else on it. Ready to just send it back at this point.
