I currently have one of my two SDC 9 with a high temp warning, that is what lead me to this post. I can tell you from experience that the customer service was great about a year ago when I had a noise issue, you just have to use the online portal. They asked for the usual proof of purchase and a picture and I quickly received the needed replacement part. For the current problem I will clean the pump (probably due anyway) and see what happens. If that does not work I will find out if the customer service is still great.
