1999 Sundance Optima

It's been quite a week keeping the spa hot in this winter weather.

Over the course of a 2 week period I have learned quite a bit and solved one problem but another persists.

The GFI kept tripping and by elimination I discovered the the blower causing the fault.

Now the topside display and hence all control functions shutdown. The breaker / GFI are not tripped.

To clear the fault I kill the breaker, wait awhile and reset it and all is well till another episode.

I faithfully drain the spa, clean and rotate the filter every 4 months. I have 3 filters in rotation.

We use the spa all year.

I think the problem may be the HI TEMP switch. I took the the filter out and will see what happens in 24 hours.

serial # OPTI 367235

I would appreciate any suggestions.

Thank you

Still turns off. The topside paner shows ---------- and the rest is blank,

If I hit the breaker and turn it back on after 10 minutes all is well till the next event.

Watch dog mode. 99% time it's the temp sensor.

I agree with your suggestion. After research and reading and trouble shooting the spa systems all indicators are the sensor. I will order a replacement Temp Sensor.
