Keep in mind though that the switch above is also a main culprit for that problem as well. Even though for yours it was the fuse, mine had the same problem and it was the switch. It was stuck on & never registered. So if you started destroy the ring your ball was effectively over cuz the mode could never finish nor timeout. Can't do anything else until ball drained.
But thanks to this thread I'll know to check fuse 20 if it happens again. Thanks for the tip.
