We bought a home with a baqua spa hot tub. It keeps tripping the breaker so we googled and figured out the issue. Everything works fine when the heater is not plugged in. My husband looked up the cost of a new one $150. Is this something that's pretty easy to replace or left to the professional.? Wondering what it would cost to replace. Husband talks of not fixing and filling it with dirt lol. He's afraid it'll become a money pit. I am more hopeful.
