When pressure/flow switch, temperature sensor, and the overheat sensor pass
testing, the spa goes to
#1 and #2 CLICK and then Nothing.
You get the SECOND CLICK then nothing: The 2
nd
Click turns on the #1 or LOW
speed pump (see Pinnacle models section for exceptions.)
If the pump comes ON and you see water movement you know the pump is OK.
If you hear the CLICK and the pump doesn’t come on, one of two problems
exists. First, the #1 pump/motor is bad. Second it’s the pressure switch has failed
or needs adjusting. Final indication is a board failure; rare but happens.
So, to check first and last, check the voltage to the #1 pump. To do this you need
your voltmeter set above the voltage of your spa. If you are running the spa on
110-130vac, check for that voltage. If 220-260vac, check for that.
On 2 pump, 220vac systems, the #1 and #2 pump are labeled. On most spas you
can just ID the 2 slots the pump wires use for the white and black lines and check
the voltage for 220-260vac.
On one model, since the plugs connect to the control box from the bottom, you
must change how you reach the wires to check. Because it’s impossible to reach
the wires, you need to open the cover on the control box, ID the wires you want to
check and check the voltage that way. Be very careful to place the probes on the
correct wires and not to short anything.
If you have a single, 2 speed pump, the LOW speed is the white and black wires.
Do as explained above to check the voltage.
If you have voltage, the motor has failed and you will need to replace it. One final
double check can be done on 2 pump systems. You can unplug the #1 pump and
move the #2 pump to the #1 spot and turn on main power. If the pump now
DOES come on, you have shown the real #1 pump has failed.
