Question about Pool & Spa

1 Answer

I have an older jucuzzi spa. Model number z140. I had one of the primary wires burn through some time ago. I repaired this and the spa ran fine until yesterday. It quit running, heating, just plain quit. I checked it today and found one of the smaller wires that connected to a lug on a part that is on the PC board was burned but not burned through. There was enough wire there that I could cut the bad part out and put a new connector on it. This did not make the spa operative. The gfi breaker has not tripped through all of this. There are two fuses on the PC board. I checked them out and they are ok. Any suggestions as to why the wiring keeps overheating and now the spa doesn't run.

    Thanks for the information. You are right on base. While waiting for this answer I contacted a very helpful man by the name of Bruce at Clear Creek Spa in Commerce City, Co. who gave me the same advise that you gave me. I did replace the PC board and am soaking again.

    By the way, maybe I can help you or someone you know. I have what is called "Restless Leg Syndrome". My legs occasionally move involuntarily. Not fatal but very annoying. Soaking in the hot tub, or even a hot bath I presume, helps me eliminate this and allows me to get back to sleep at night. If you know anybody with this same thing pass this information along. I think they will thank you as I am for your information.

I have found that most wires that overheat were caused by a loose connection. Wheather is was at the terminal screw or a bad solder joint on the circuit board. When there is enough heat to "bake" a wire, it most likely damaged the board as well. Check the traces on the back of the circuit board.
When you have a connection that is loose and "making & breaking" you are most likely to find carbon build up on the wire/ connector itself and it needs to be cleaned if not replaced.
Or keep it simple & replace the circuit board. Good luck

What does "Firmware Rev B 13" n on indoor control panel? Help! Robert

The firmware message is the firmware on the wall mount control. The wall control would seem to be getting power, giving you the firmware rev only. Your communication with the main board has been lost, broken wire, main board has gone bad or for some other reason can not receive and instruction from the main board. If you have a spa side control, if spa side works then board may be ok, look for bad wire. If spa side is not working disconnect and power cycle the system and try the wall mount with spa disconnected. You may only need to replace the main board. More info on your system would be needed in order to suggest the proper replacement.

GFCI in primary power cord keeps going off turning off the hot tub.

This could be a number of things. First make sure your water flow is not impeded. Clean your filters or replace them check that there is no debris in the intakes or returns. There are fuses for each item from your power pack, you can unplug everything, lights, blower, pumps etc.. plug them in one at a time and when the GFCI trips that is the fuse you need to replace. Lastly, you could have a siezed motor or a bad GFCI for this you may want to call out a professional hot tub service company in your area.

Spa has 20amp fuse that blows whenever I either restart spa or turn on jet pump. I disconnected pump and it ran fine until I restarted the spa and fuse blew again.

something is drawing a load when it shouldnt be. remove all circ pumps, booster pumps, and disconnect heater element. turn on hot tub and see if it trips. then do the same, re connecting the element, and pumps, one at a time. when it does trip, thats where the problem lies. bad pump or element

My spa won't blow bubbles but it will heat up. It

You opened the air valve??? Usually a round thingy on the edge of the tub.

I cant imagine how this would not work if it were open ... it works on the same idea as a carb on any gas engine. If the hole is open, the water stream will **** in air.

Pool heater works, but smokes and bangs when pool is turned off.

Yes! It is dangerous. The pressure switch is malfunctioning and allowing the heater to remain on when the pump shuts off. You should not use the unit until a qualified repair tech can look at the unit. There is only one other set of limit switches that are turning your burners off before the boiling water bursts the tube bundle so if they fail to react in time, you'll burst the heater, cause expensive damage and risk injury.
