I hope someone can help us with our hot tub worries. Can't afford to spend any more money at hot tub companies. Too expensive. We have an article spa (coyote spa) the pump has low n high speed but once installed now is only running on high speed. I cannot get it to run on low. Does anyone have any answers on any way to troubleshoot n find out the source of the problem? Also how do I check fuses. Thank you all. Will wait for replies.
