Wow, thats an old one. What is it, mid 1990's. Most people won't know what to do with that which is probably why you haven't had many replies. I suggest going to www.rhtubs.com and find the forum. Post the problem there. If you are lucky, n1oty will answer. He's got a lot of experience with Jacuzzi.
Thanks for the info and reply. I will try that.
