Hey everyone, new to the forum. I have a Dreammaker Spa with the Balboa pack (RS101 / 56403-05) and lost heat. Checked flow and it seems good. Replaced heater, checked fuses and checked water pump. All seem fine. The tester shows there is power to the heater so? I'd hate to throw a control board at it but just not sure what else it could be. Any help is appreciated.
