I am not an expert, but I would first suspect that you have a bad temp sensor. This is easy to replace and fairly cheap (off of ebay about $22 for one common one). There could be something more serious going on like the PCB, but likely something simple but hard to pin down for sure, if you know what I mean.

: I also have the older Softub with the 2 dilas and three menbrane buttons
: with the 3 LED's between the two dials. My problem is the temp dial
: is on the highest position but the tub max temp is slowly drooping.
: Used to get 104 degrees when the dial has some more room to turn, now
: the dial is at the max and the tub temp maxs out at 102. Pump works
: fine, don't know if this thing has a thermostat or if the heater is
: going. I'm a repair guty and can handle the repair, just don't know
: whatbthe problem is and where to get a replacement. thank You
