Alright - this is my first post and it is not a happy one. I drained my Hot Springs Spa today just doing routine care, but I did not secure the power. It looks like it was aerating, for about an hour with no water. Im an idiot so please, no need to reiterate that point, but could someone please tell me how bad this could be?? The pump comes on but after about 2 minutes it starts to squeal. Thanks in advance! Ken
