mistermoose Posted September 22, 2014 Report Share Posted September 22, 2014 I recently made a mistake and purchased a second hand hot tub from what seemed to be a reputable seller. Unfortunately he took the money and ran on me and I am stuck with a tub that is overheating daily due to what seems to be a bad setup. Hopefully someone can give me some insight to help me fix the issue. The tub is a Leisure Bay with the Extreme Tech Genius Controller. The control panel model is a Balboa 51789, the LB104. This give me the option to have 2 dual speed pumps and an optional circulation pump. The current set up has 2 single speed pumps and a blower. The pumps are both Emerson 3hp, 11 amp, single speed motors. Pump 1 which runs the main lounge jets and heater is wired up as a circulation pump, running all the time and Pump 2 which runs the rest of the jets is wired to the Jet 2 button. With this setup, the 11 amp motor running non-stop creates so much heat, that even with the heater shut off, the temp continues to rise a degree every hour. This setup seems completely wrong. Shouldnt the optional circulation setup only be used if you had a dedicate circulation pump and instead In this configuration, shouldnt Pump 1 be a dual speed pump, wired to the Pump one relay? Am I correct in understanding that wiring it in this manner, Pump 1 would run on low speed continuously and high when the Jet 1 button is pressed? Any knowledge would be greatly appreciated.

PreservedSwine Posted September 24, 2014 Report Share Posted September 24, 2014 You are correct- the 11 amp motor should only be running when the pump button is pressed. Something is wrong. The spa came from the factory with a circulation pump- are you sure it's no longer there? Quote Link to comment Share on other sites More sharing options...
mistermoose Posted October 12, 2014 Author Report Share Posted October 12, 2014 Yeah I am sure there is no circ pump. Not to say there wasn't one originally. The way it is plumbed right now, I dont see where it that the water pickup would come from unless they change all that as well. As it is, I bought a new pump, 2 stage pump and added it in. Now pump 1 is the circ on low whenever the heater is on and during the filter cycle twice a day. Is that enough water circ or should I purchase a small circ pump, replumb so that the water from the additional circ runs just through the heater? Input is greatly appreciated.

PreservedSwine Posted October 13, 2014 Report Share Posted October 13, 2014 That's fine- no need to add anything Quote Link to comment Share on other sites More sharing options...
mistermoose Posted October 13, 2014 Author Report Share Posted October 13, 2014 Thanks for the input and info. Now if I can just figure out why the blower suddenly is running out of control, Ill be good. Fix one issue and another pops up. Quote Link to comment Share on other sites More sharing options...
