Both motors went out in my 2009/2010 Caldera C46 hot tub. I didn’t repair for a while and recently bought new motors and wet ends and replaced the old ones. The motors won’t start. In looking at the controller board, I get a solid red light on D17, when I cycle through the button to start the motors. There’s no literature that I can find that explains what this is. Checked fuses and they are good. It’s not tripping the breakers. And, I’ve been waiting on a technician from the local dealer for two weeks. Any thoughts?
