I bought a new HS Vista this spring and so far am very happy. Recently, I have noticed the lights on the Fontanna water fall are not syncing correctly. When I have the lights on white, 2 may be white and the third may be yellow. When I called my HS dealer for service, they came out and looked at the tub, took the panel off directly below the water fall, and said they had to order a part. After waiting 2 weeks for them to call and say the part is in, we would like to shedule a time to come out and fix it, I called them to check the status. They stated that it was now too cold to come out and fix it that I would have to wait till spring. They stated that with the extreme cold weather, that they could possibly break the panel they have to remove to get to the part that needs replaced. First, I think it is bad customer service that I had to call them and secondly, is the cold a legitimate excuse or am I being fed a line of bull?? FYI I am located in Northern Illinois.
