We bought our tub 4 years ago and have replaced just about every part on the tub except the cover, outside and inside closure. We have gone thru 3 pumps, 5 jets, the whole sound system, and main brain of the tub. We have had to disconnect the water fall because the clamps keep breaking over the winter, so we just stopped using them. We are glad we have someone that will work on this piece of junk. We love the hot tub when it works but it has cost us so much money to fix. The customer service and parts department have no clue what they are doing. They don't know their own product or part numbers.
