Jacuzzi JT365 Curc Pump goes again they say it gets clogged

(1/6) > >>

Spinner71:
Hello All,

I am so disappointed with my Hottub... The company I bought to from now is out of business and the service contract went to another dealer. They have been helpful replacing my curc pump 5 times in the last 6 months. I keep getting the FL1 error. This shuts off my heater and now with winter coming I am a little worried. They say the cerc pump keeps getting clogged and I have ran every known cleaner I was told to use to clean the pipes. I replaced the water and everything runs fine for a few weeks and again last night the FL1 is back. The filters are only 3 months old I clean them every 10 days. I took out the filters and I dont feel any suction on the side with the grill on. I do feel suction on the other side. I turned off the hottub for 20 min and the FL1 is still on?

Please help anyone...

Cheers
Jason

I'm no expert on HT, in fact I don't even have mine yet. but if you have a wet dry vac can you try to suck out the blockage? Or use (regulated) compressed air to blow it out? I'd start at say 10-20PSI. I'd also disconnect the circ pump and check for blockages at the inlet of the pump. Good luck.

Yeah I have tried all that... I guess Im looking for any info on how to clean the pipes. I dont think they products I have used are getting all the calcium or lime off the walls of the pipes. When they replace the pump it gets clogged again and shuts down the heater.

Thanks for your input

Oh ok. you have calcium deposits in the plumbing lines. I never would thought that would be an issue. :o How about a snake? If the pigtail end is to big you can flip it around and use the other side, its a 1/4" snake so that should go thru the system.
You may want to try some CLR. http://www.thecarycompany.com/containers/facility/clr-multisurface.html?gclid=CObEo6yx2KUCFRJY2godOQ3tng
Just thinkn.....

When I cleaned HVAC lines of deposits we used diluted acid pumped thru the coils. I'm not sure how a HT's sytem would like that. But being mostly plastic it might be ok.
