Question about Aqua Flo Aquaflo Flo Master Xp2 Spa Pump 1.5 Hp Two Speed

Open Question

Hi. I need to connect the Aqua Flo XP2 pump in my hot tub to a new Balboa control pack but the heater cord wires are different colours. In the new cord there is a green (earth), a red, a white and a black. Where do they go? There are six connectors in the box on the pump, labelled U1 U2 V1 V2 W! and W2. There are also two large capacitors in there. Thanks for any help!

SOURCE: Where cani find replacement thru-bolts for an Aqua

A local motor repair shop would have the thru bolts. If you have at least one good one, you could match up the size, and cut soem threaded rod. Most motors this size use either 8-32,10-24,or 10-32 bolts. You can buy threaded rod at hardware store. Try to find galvanized, to prevent corrosion, or paint the part inside the motor if you cannot.

The pump will rum on first stage but is tripping power on second speed

Hi Martin, Thanks for the question. It sounds as though the pump relay or the pump itself is fried. I would recommend calling a service technician. If you know how to check voltage yourself, use a multimeter or (fluke meter) to test the voltage between the pump relay. if that reads normal then test the pump itself. It could be the difference between buying a new pump, or a new spa pack. I hope this helps, Thanks again!

My hot tub is leaking from one of the pumps. how do i change the pump?

Sounds like you need a new Mechanical Seal for the wet end. Pretty simple job to change the seal kit.
It is also a lot cheaper to do that than purchase a new pump.

I was told that the Aqua Flo Master Xp2 Spa pump 1.5 hp 2 speed pump was the equivalent to the Sta rite Max E Pro 2 speed pump but then from another source was told that the Aqua Flo was not made for in...

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.

My hot blows the fuse just as soon as I turn it on, I unhock the heater and it still blows the fuse. How long is the motor gauntee for Flo Msater XP2-551521

1 year.

If you disconnect the jet pump plug from the control box can you turn on the service and not blow it again? That would be the easiest way to confirm a motor failure is your problem.

Need to know where wire that comes from controls on hot tub connect to pump at?

Thank you for posting your question here on

Assuming you have a standard white, black red, green cordset, green to ground, white to common, red to high and black to low. If the speeds are ‘reversed’, interchange the red and black leads. You likely have an AOSmith motor which will be labeled 1, 2, ¾ on the terminal board. 1 is common, 2 is high and ¾ is low.

The fault is most likely to be the condensor. They can and do fail at an early age.

You don't need to dismantle the pump, on the rear of the pump you'll find a slot on the motor shaft which can be turned with a screwdriver.

If you've only just reffiled the hot tub it could also be an airlock.

I have a flo-master 06620390-2 pump that failed in my hot tub. Is there a quieter and more efficient replacement or should I replace with same?

You are generally better off replacing the pump with the same model. Hot tubs are noisy unless you have a really good insulation job. It is unlikely changing the pump will make it any different as far as noise goes. The flip side is that the manufacturer sized the pump to match the hydraulic load present within your specific tub and to provide the necessary flow rate to keep the water clean. It can lead to problems if you put in the wrong replacement unit.

If you would like a quote on the replacement motor and/or pump end, contact us thru
