Jacuzzi Spa 355 temp sensors tripping breaker

[ewsb]

Within about 5 to 20 secs of turning on the breaker the unit trips the breaker.

I removed each pump and sensor 1 at a time and have isolated it to the temperature sensors. With the sensors disconnected all other equipment operates.

Any guidance on what to do or replace the sensors? I can see the position of one of the sensors with ease but the second seems to go through conduit back in the tub so I am not sure where it goes?

Where can you buy these sensors from and is the easiest thing to replace them? (if I can get to the second one?)

Many thanks

Sean

It looks like you have a temp sensor and a hi-limit/freeze sensor connected to the J2 found on page 39/40. http://www.jacuzzi.com/hot-tubs/brochures/2007_LED_Manual-J300.pdf

Does this look like the one you have? Jacuzzi Temperature Sensor for LED J-355, J-365, J-375 [6600-166] - $31.00 : Forty Winks, Best Buys on Famous Maker Mattresses, Jacuzzi Hot Tubs, and CL Bailey Pool Tables

Yes thanks - that is exactly right.

And the problem is solved. It appeared to be water that had got into the heater. Once the unit dried out, everything was perfect and back into operation.

My supposition was that with the hi-limit switch disconnected the heater and thus is did not work. When the heater was not working, the master switch did not trip (and all the other pumps worked) As soon as the heater operated, it tripped the master.
