2006 Sundance Marin Hot Tub

The hot tub is working fine but on the control panel it is displaying what appears to be 919 then flashes to display the temperature (103 f) then back to 919. I have shut it off for approximately 10 minutes then back on again and it’s still doing it.
Any suggestions please and thanks.

    Lin this sounds like your ClearRay Uv counter has expired. To reset the counter simply depress your cycle button 3 times if you are in Standard mode. Once the display says U press the select button and it should say On. Press the cooler button to say off and then the warmer button to say on and the counter is reset. If you don’t have ClearRay installed leave the counter in the Off position.
