Hot Springs heater bypass

(1/2) > >>

Dougstermd:
Resurrecting this 2000 model G. Heater was shot and in pieces. I disconnected the heater and put a bypass hose on the circulation pump. Filled with water and hooked up power. Circulation pump is operating I’m sure it’s looking for a temperature signal. Power light is flashing indicating over temperature sensed.  How can I start the jet pumps with a fault code? I would like to see both pumps operating before ordering a heater.

Chas:
Actually, if the power light flashes, yes it's showing overheat, OR the sensors may not be plugged in. If BOTH power and ready lights flash, its the pressure switch.

You need to take the two temp sensors off the heater and plug them in to the control box.

Assuming they are both good, red light should stop flashing and jet pumps can be turned on.

If your heater has the pressure switch (two sensors and a third small grey wire coming out of the end of the heater) you will need to shunt the wires from the pressure switch. There is an actual part number for a pressure switch bypass, but I usually just cut the wire, strip the red and black and crimp them together.

Failing that - simply hot wire the pumps over to incoming 220 - one at a time, power off, of course.

Ok plugged in sensors got a solid power light was able to get one pump to start couldn’t figure out how how to start the other pump. Back lighting on the led display seems to not work. I never got a ready light. Is there any overhaul kits for the external control panel

Ok got both pumps to turn on.
