Thank you.

Acquired a Jacuzzi Santina hot tub when I purchased a home about a year ago. Just started getting an overheat (OH) error; unit had been working properly before (so far as I know). It has been hot outside lately (around 90 or so), but I am surprised that this is happening all of a sudden. The water is definitely hotter than it's ever been before, and it's set low (around 95). Pump and heater were supposedly replaced about 2 years ago. I tried swapping the filter, but waterflow seemed fine (the "Water Rainbow" and jets seem to have usual power). Issue persisted with a clean filter. Is there any troubleshooting to do on this? The control panel is simple -- a red LED display, a temperature button (up/down), a pump button (hi/low), and the light.
