I have an o-l-d Hot Springs spa - manufactured (according to notations inside the pump area) 2/5/1987. I bought it second hand and it functioned great. A few (5-7) years ago, the cover decided to disintegrate and I quit using the spa. This was in the winter in Kansas. I drained the spa with the intent to replace/repair the cover the next spring.
As often is the case, the repair/replacement of the cover never happened. This spring, we decided to put our house on the market and move closer to the grandchildren. Naturally, having a working spa would add value to the house so I decided to see if it was in working order.
The insulation around the heater had deteriorated so I replaced that with expandable foam (after removing the heater from the spa), cut it to shape, wrapped the heater with metallic tape and reinstalled it. I cleaned the tub and filter. I filled the tub (after replacing the drain cap which had been left off since draining) and started the jets. Wonder of wonder, after sitting idle all those years, the pump worked and began pushing water through the jets. It also started pushing water through numerous leaks in the pump! I have since pretty much stopped all the jet pump leaks and have not noticed any others in the spa.
Now, however, I am having issues with the heater/circulating pump. When I set the thermostat at the midway point (5 on my dial), I can hear the circulation pump start to work. Checking the pump one hour after starting it, I found it to still be working. Checking the pump after two hours, I found that it had stopped and the system (circulation pump, jets pump and heater) were electrically "dead" - nothing worked. I have done this several times as the spa/electronics seem to come back to life after several hours and pushing of reset buttons.
On one occasion I was able to get it to last 5-6 hours by:
Setting the thermostat to its lowest (i.e. the point where the "relay" first clicks on)
Checking it and running the jets for several minutes on an hourly basis
Increasing the thermostat each time it was checked
It finally "died" once the maximum thermostat setting was reached. Usually, however, it "dies" somewhere within one and two hours of starting.
I had a GFI outlet with reset buttons installed when I first put the spa in place. Each time it comes back to life, the GFI reset and spa reset buttons have been pressed. At this point, however, I don't know if the spa is causing its own "death" or if the GFI is the culprit nor do I have the knowledge of how to test/determine that.
Any suggestions/ideas/advice/instructions would be appreciated. (Or maybe I'm just "beating a dead horse".)
Thanks in advance.
