mando Posted October 15, 2010 Report Share Posted October 15, 2010 Hello – Searched but could not find something specific to my issue. We have a Jacuzzi J-370 portable spa that is about 8 years old. Never had one problem with it but about 2 weeks ago we started noticing the pump 1 motor running louder. The noise has steadily increased to the point we cannot run it because it is so loud and obnoxious. Since it was shut off because of the noise, we took the opportunity to clean it, replace the filters, and change the water. Upon restart the pump 1 would run at a normal noise level but only for about a minute and then click off. The pump repeatedly tried to restart with the same result. So we again turned it off and then back on. Then the pump 1 began running no problem but again VERY loudly. The spa other than the noise works fine. Any thoughts on what could be going on with pump 1? I realize this is an older spa and to date we have never had to do anything but normal filter and water maintenance on it. Thanks for any feedback!

mando Posted October 15, 2010 Author Report Share Posted October 15, 2010 Just to add a little further clarification in case it matters. Pump 1 is our circulation pump. Quote Link to comment Share on other sites More sharing options...
Beefcake Posted October 15, 2010 Report Share Posted October 15, 2010 Just to add a little further clarification in case it matters. Pump 1 is our circulation pump. Sounds like the motor may need to be replaced or at least refurbished by a technician. Refurb would be the likely cheaper option. Quote Link to comment Share on other sites More sharing options...
mando Posted October 15, 2010 Author Report Share Posted October 15, 2010 I read somewher else it could be that the ozonator has gone bad since the pump works fine except for the noise. Anyone know if that is a possible culprit? Quote Link to comment Share on other sites More sharing options...

Anyone know if that is a possible culprit? no. Replace the motor and go new a rebuilt one could last years or moments.bite the bullet pay the money you will be happier in the long run.

mando Posted October 15, 2010 Author Report Share Posted October 15, 2010 How hard is it to replace the pump in this model does anyone know? We are fairly handy but is this something an expert should only do? Quote Link to comment Share on other sites More sharing options...
Spa_Guru Posted October 15, 2010 Report Share Posted October 15, 2010 Classic example of a pump seal leak killing the front bering in the pump, pump seals usually die from chlorine/bromine exposure over time. If you keep a closer watch on the pump seals dripping, it is a lot cheaper to fix before the bering is toast. Quote Link to comment Share on other sites More sharing options...

I noticed there are all sorts of brands of pumps. Should we stick with the Jacuzzi J Series brand pump or would there be another brand that we could also use? Thanks again!

mando Posted October 18, 2010 Author Report Share Posted October 18, 2010 Hello again - Any recommends on good sources for a pump for the J370 Spa? We purchased it in 2002. We opened up the spa this weekend and the pump is a Century Serial BX6-24, A.O. Smith Part 7-193227-01, Continuous 2.5hp, amps 11, HZ 60, Volts 230, RPM 3450/1725. Obviously I wrote down any number I could find on the thing Any advice on a model that is comparable. Given the age I cannot find this one on the internet thus far. Thanks again M!

Thanks again M! as long as the motor fits and the volts and amps match the only thing that might give you a rash is the wet end part those can be specific to a spa manufacture Quote Link to comment Share on other sites More sharing options...
mando Posted November 6, 2010 Author Report Share Posted November 6, 2010 Hello - Spa Savant or anyone else who might know. Does the spa need to be fully drained to change out the pump 1? Thanks so much! Quote Link to comment Share on other sites More sharing options...
jaysdca Posted December 22, 2010 Report Share Posted December 22, 2010 Hello - Spa Savant or anyone else who might know. Does the spa need to be fully drained to change out the pump 1? Thanks so much! Yes it does. Your new pump will likely come with the wet end needing to be rotated to fit your application. Quote Link to comment Share on other sites More sharing options...
mando Posted December 22, 2010 Author Report Share Posted December 22, 2010 Just in case anyone else has our problem I wanted to report back on our results. Thanks to this forum we attempted and were successful in replacing the pump ourselves. It was indeed the pump 1 that was out. I researched and ordered a new one online. The installation all in all was quite simple. The worst part honestly was getting the old pump out because it was shoved back in behind all sorts of stuff. Follow the wiring instructions on the new pump. This will not necessarily match the wiring of your old pump as we found out. Definitely use the o ring grease mentioned above. We had it but in hooking up the pipes forgot to use it. Everything leaked. Once we applied the grease all was good. As reported with many Jacuzzi’s we had issues getting the spa to re-boot without showing the FLO error message. It took about 4 times and a couple days of performing all the tricks to clear the air before it finally worked. It does this when we switch the water too so we expected it. It just took longer and more work this time around to clear it than usual. This is definitely something that is not hard to do as a DIY project. Good luck!
