My D1 Diplomat hot tub keeps setting itself to 104F. When it does, it won't let me lower the temperature...it just counts right back up and sets the temp to 104F.
After several hours it will allow me to lower the temperature, however, as soon as I use it the same thing happens again. The repair guy has been here twice and has yet to fix it.
Any ideas as to what the problem is. The tub is still under warranty and I just want to get it fixed!!!
Thanks,
Mike
