They also hold the motor together and removal will likely cause the motor to
disassemble.
D. If you are replacing the pump (wetend), reverse. If the motor shaft is
corroded, you need to remove the rust. The least abrasive method is best. Start
with steel wool, then try a wire brush or even sandpaper. You need to have a
clean motor shaft so the impellor can tighten cleanly against the seal and make
the seal work. If the motor shaft is highly corroded, the new impellor will not
tighten against the seal and the pump will leak.
E. If you are replacing the motor, you have to move the motor cord from
the old to new. The motor is only a 110-130vac motor so you don’t have any
internal wiring to change for the new motor. Note the wiring sequence on the
label of the old motor in reference to the color of the wires. It will show a neutral,
low, and high plus ground sequence. Compare to new motor label and make sure
the wires go to the same speed.
Circulation Pump:
Most Gatsby models have a 24 hour circulation pump. It sits next to the heater.
When power is applied to the spa the control unit turns on the circ pump. So it
runs all the time. Because of that, normal life is between 5-7 years. Also
individual parts are hard to obtain and usually only extend the life of the
pump/motor marginally if at all. So service techs routinely replace the complete
pump/motor circulation pump and you should too.
Your circ pump is either 115v or 230v. The label on the motor will identify which
you have.
Replacement is simple. When you get the new circ pump, confirm you are getting
the same voltage pump. Note the discharge direction of the new with the old.
Sometimes you have to turn the pump ¼ turn to match. This only requires
removal of 2 screws. Gatsby replacement circulation pumps come with a cord so
it is an unplug, plug situation.
Usually I do not drain the spa. You may choose to do so to avoid lack of need of
speed. I have found that usually I keep the old pump bracket in place. I remove
