My spa went through the ringer this last winter. After replacing all burst pipes, leaks, the wet end, pressure valve I thought I was on my way to a nice soak. But the whole system shuts down at 100'. It heated up fine but once it hits 100 the system shuts down and trips the circuit. Any ideas would be greatly appreciated.

Thanks,

Mike
