I have the same spa pack
gecko In.xe-5-11-h4.0
had a oh error and a nr error
figured out that pump 2 is running on high all of the time. Heated up to 112
i unplugged pump 2 and tub works perfectly. Going to change the relay if I can. Does anyone know… is that changeable or soldered in? Does anyone know what relay I would need to purchase?
