Temperature Sensor issue after using "Fix a Leak"

[serge9898]

I had a minor leak to fix in my HotSpring JetSetter. (Couldn't find it)

I bought a 8 oz bottle of "Fix a Leak. The Only One". Followed the instructions: Top the SPA level, lower the heater at 80F (min), poured ~2-3 Oz in the SPA after removing the filters. Let run the pump for 12 hrs.
The leak seems to be fixed.

But the SPA temperature is now 45C / 115F (command is still on 80F) and the Ready indicator lamp is blinking. Manual trouble shouting section says "Temperature sensor problem".

I am guessing that this great Fix a Leak product clogged the temperature sensor.

- Where is the sensor located?

- How do I fix that? Should I open and clean it?

- Is there any other parts that need to be unclogged (like the ozone sanitizer)?

Thank you!

not sure about your spa, but on my spa the temp sensors don't touch the water at all.  They sit in pvc channel that is right in the area of the control board.

If your sensors do touch the water, they should be removable.  I would find them and clean them.

On my 1988 CalSpa, the temperature sender is also not in the water path, in a metal channel of its housing.  I've also used Fix-a-Leak for a few years, like twice a year, because I cannot locate the source of the leak.  It does the job for me.
