Question about Pentair Minimax NT Heater

1 Answer

Mini Max Digital Control FLO error message

Pump only working on high speed after 30 minutes it cuts out as designed to but flashes between the temperature and FLO and water does not circulate to go through the heater. Have checked filters, bled the pump. Have read that it could be the pressure switch staying closed. Can you please tell me how I locate the pressure switch? Any ideas what the trouble could be if it is not the pressure switch? Thanks in advance for your help!

The pressure switch is on the inlet/outlet manifold. It has purple wires running to it. Try taking a wire and unplugging the pressure switch and jumping the 2 wires together.

What does mean FLO message on the digital panel


Hi Simon,

The FLO message is a warning that your water flow is not what it needs to be. This can be harmful to your equipment, without proper water flow the heating element can over heat or your pump can run dry causing damage. Often this is can be caused by dirty filters, so your first check should be to see if your filters are clean. Other possible problems could be water levels. Make sure you have no water blockages especially on the suction end.

Aqua Flo Flo Master won't start on low speed


Water flow error on hot tub means low water flow. This is not enough water flow to turn the system on.
Some motors do have a start capacitor on them. you can certainly check that or take it to your local motor repair shop and they can check that for you.

I responded to the previous question in regards to the motor only. The xp2 does not have the strainer basket that the max-e-pro has . If this was a regular hot tub, the xp2 would work great, if this is above ground, then you do need a pump with a strainer basket. Again the xp2 will not work for an inground hot tub as the set up is different than an above ground unit.

The side of the motor will have a wiring diagram for how to connect the common, low and high speed leads. Your wire harness should have a white (common), black (usually low), red (usually high) and green (ground) wire. If high and low are backwards, switch the black and red leads.

Hot tub pump stops and control panel says there is a flo problem


Yes a pump does have a thermal cut out. When the motor gets too hot the thermal cut out will activate and the pump won't restart until the motor has cooled.


If you were an electrician, or highly confident/competent with electrics, you could test the motor with a volt meter. Run the spa and as soon as the pump stops running, check the voltage at the pump. If there is voltage at the pump, then the thermal cut out on the motor has activated. Do not try checking this yourself if you're not competent to do so.

You could also do the same test at the spa pack if it's easier to do so, just locate the output to the pump.

What spa and which spa pack have you got?

Cheers,
Ian.
