I had the same problem. Disconnected the spa wiring from the breaker to test the breaker - breaker stayed on fine. Reconnected then spa. Disconnected the heater (both the power contacts and sensor wires) - breaker tripped. Disconnected the blower motor - behold, the breaker stopped tripping and the spa showed a sensor error. Left the blower disconnected, reconnected the heater contacts and sensors, and the spa has been heating for the past three hours just fine. The jets work but I have no bubbles until I replace the blower motor - no big loss there. I'm very happy I can get the water heated before the incoming freeze this weekend :)
