Hey,
I recently inherited a Sundance Rio 98 spa with a house we purchased during the winter. Soon after, we noticed we started getting a FLO error, so, we drained the tub for the winter and restarted it up in the Spring.
We called a service shop and got a few parts replaced - filter, circulation pump, flow switch
So, during the summer we would sporadically get the FLO error again and the only way to fix it was to power cycle the tub and everything went back to normal.
So, we started getting it again! Here's what happens:
So, last weekend we went in the tub (at 100 degrees) and when we were done, we put the temp down to 90 degrees. Today, i checked on the tub and the temp was 93 degrees, and we decided to go in tonight so we put the temp back up to 100 degrees, and got the errror!
Any ideas?
