Thread: Great Lakes Spa with Balboa guts
12-20-2012, 10:31 AM #1
I have an older Great Lakes spa that has balboa spa pack that is not heating. I have had several issues with the spa in the last year including new heating element, new circuit board, new pressure guage, new motor/pump. I recently replaced the motor and pump and fired the spa up after it had sat for several months empty as I debated on buying a new motor/pump.
The spa fired up but would only heat to 80 degrees. I pulled the heater and was going to replace the element but could not remove the heater from the heat tube as it has rusted in. I bought a new heat tube, with heating element and pressure guage. I put in the new equipment and turned on spa and now I have no heat, the heat light does not light on the control panel, there is continuity in the pressure guage with power on and spa running. There is continuity at the heater. I removed the filter to make sure I had good flow. I have voltage to the circuit board before the heating circuit but zero volts after the circuit. The high limit is a circuit on the board and not a separate switch. Everything else on the tub works, light, blower, motor/pump, the heat is the only thing that does not work. Any ideas? I am running out of options at this point.

There should be a tempeture sensor on the spa that may be bad. Spas will usually have a high limit, temp sensor and pressure switch. Are you getting any error codes on the display?

With no heat indicator coming on you are not getting a call for heat, something is preventing that, either low flow from pump or sensor will usually cause this. Do you have the spa set in standard mode? Some of these Balboa systems will have a sleep mode and just want to confirm which mode it is set in, economy, standard, or sleep if it has this.
