My control panel died on my 2011 Hotspring Aria. Found that my control panel is 'discontinued'. The replacement sent looks, and I suspect, works the same. BUT NO !!!!. The connection on the cord from the control panel to the motherboard is not the same. Of course no adapter either. So what does Watkins have to say? To make the replacement control panel work, you must buy a new motherboard. Which is close to $800 plus the control panel, close to $300.
I don't know if this is planned obsoletness (sp) or what. My tub isn't even close to 10 years old.
I will put out there, DO NOT BUY ANY WATKINS MANUFACTURING HOT TUBS (Hot Spring, Cal Spa, etc). Their proprietary parts are junk, or the parts don't exist, forcing the customer to have to buy supplement parts to fix the original part.
Be Careful out there.
