Hi, my name is Jeff and I'm new to the forum. I have a United Spas S300 I'm having issues with. Hot tub came with the house I bought and seems to be well taken care of. Once I fill her up, she heats to the 104 degrees, then eventually burns one of the two heater wires randomly. Everything seems to run fine, just keeps burning the wires. Not sure if I need to replace the unit that the wires are connected to or what. I know the hot tub sat for a few years. Hot tub is inside out of the weather in it's own little hot tub house. Anybody had this happen or familiar with this situation. Any help would be great and thank you in advance. I couldn't figure out how to upload pics in this forum so I pasted links to the picks of the burnt wires and model/serial info. Thanks again.
