Wayne,
Thanks a million for this post. My Hot Springs spa stopped heating about a year ago. I (like many others) assumed it was my heating unit. I would have replaced it had I had the money. I just drained it until I had the time and money to attempt a fix. Last week I decided to do a little more troubleshooting and found this site. Your post prompted me to look at my relay and I found that it had the same burn marks as yours. I found the replacement relay board for a good price on ebay and installed it today. Now we have a hot tub again instead of a cold tub. Without your post (with great pictures and information) I would have still been lost. I would have been out $300 if I would have bought a new heater. And for the record, I replaced the circulation pump just before the board blew. I used the same pump you did. I too am flabbergasted that Hot Springs has not owned up to their mistakes and recalled these items. Thank you again for your post.
