Question about Pentair IntelliFlo VS-3050 & VS+SVRS Variable Speed Pump -

3 Answers

I have an Intelliflo vs3050 pump and I don't get any lights on the motor control panel at all. The circuit breaker is energized. It was working fine and one day it appears there is no longer any electricity getting to the motor control. Any ideas to try? The motor is out of warranty but has less than 100 hours on it.

    The expert should have considerable Intelliflo experience and understand the basic schematic of the control circuits in the intelliflo motor.

  • davea2741 Aug 29, 2010

    All voltages are nominal. Power is getting to the controller. The controller appears totally dead.

  • davea2741 Aug 29, 2010

    OK, he is right. He knows a bit more about the electronics architecture. I had already come to this conclusion.

I would suspect your speed controller has failed, this is a very common problem, the output SCR's/Triac's often go Open Circuit, this then will cause the exact symptoms you describe. These fail usually because of "Dirty Power Supplied"
You will have to have this Unit attended to to replace the speed controller unit onboard.
It maybe possible to remove the speed controller and simply have that repaired, as an option I guess. However it usually pays to return the unit to the manufacturer or authorised agent, for repairs, it usually in my experience, it actually gets it done, gets done faster, and works out to be the least expensive option overall.
I have your manual below for your convenience.

IT does not have a lot to say about the issues. The thing that you need to do is get a meter and check the voltages that are present on the system. Also you need to make sure that none of the system is on a GFCI breaker. IT might be that the controller is on one and it has blown out and the motor is not.

I would suspect that the intellitouch controller might be faulty, since it controls the voltage to the motor. This is done, as I understand, through relays, so it could also very well be a faulty relay, or slightly oxidized contacts, things of that nature. Unfortunately, I couldn't run down a schematic of the system, or any very technical information, for that matter. I would refer to your literature, and contact their support center to see if they could assist you, or if there are any known issues, etc.
Wish I had more info, but this problem wasn't reported anywhere on the net, that I could find.
Good luck, hope this helps and thanks for using FixYa.

Weak return, weak suction when vacuuming


It may be the hose going from the pool to the pump intake is partially clogged. I had the same problem,, removed the hose and shoved a broom handle through it to remove tree debris.

Will my vs3050 intelliflo pump communicate with my intellitouch i9+3s system that was made in 2005?


To make these units communicate, you would need to purchase additional equipment.
The IntelliComm will provide the communications bridge needed to operate this equipment with your existing model. Below is the manual for intellicomm and it has detailed instructions on how to connect this device to the intellitouch using various different methods.

Motor will not come on everyday. comes on some days and then others, you have to start it manually. Replaced control panel 6 weeks ago and worked fine, now same problem again. Motor runs at lowest speed...


FIRST: When you shut the breaker off and then back on was it because the breaker was "tripped" ?

SECOND: Does the motor run "hot"? Feel the outside of the motor casing when its running to check. ****becareful - it may be really hot****

As soon as you get back to me with the information I can tell you what is going on and what direction to go in. Thank's

I want to know the components required to make 6HP load pump pane


You havent indicated what voltage of phase. Is it single phase or 3 phase. 120V or 480V? Bacically you need some type of fuseable disconnect (breaker or fuses) a motor starter (contactor with overloads) and something to control the starter (either manual starter or coil energized starter controlled remotly. A good source of info is: www. Mikeholt.com

Bathtub pump totally dead, pump ran dry for 10 sec, is there circuit breakers on pump motors, switch or is it the motor shot. any way to test motor with removing it?


Normally pump motors are connected on a separate
circuit with its own circuit breaker. At your house there is always a electrical control panel housing several circuit breakers for lights, power outlets, range, aircon, motors, etc...Find a tripped off breaker and reset it. To reset the circuit breaker is to switch it to off position and back to on position. Better still you may reset all the circuit breakers except the main
circuit breaker (biggest amp rating).
After resetting the circuit breakers, try to switch your
bathtub pump on, (to test it, if it is still okey). Other-
wise, your motor is damaged and you got to have the
motor rewinded, to be operational.

On light does not glow and can not "stop" the system


the rain shouldn't have hurt the control panel. it sound more like damage due to lightning.
