Well ... long story short, I have a Pentair Intelliflo Variable Speed pump that was working great until just recently. From my understanding the pump was installed sometime last year by the previous home owner, pump has manufacture date of May 2014, controller says 08/04/2015.
The pump would work perfectly fine one day, and the next it would say "ERROR ERROR Power Failure" ... I read online and tried all the suggestions to hold all buttons and reset, but unfortunately none of which worked. It's now completely stopped running and constantly displaying that error.
I used to be an electrician so I tested and there's a solid 240 going to the controller, event disassembled the controller and can easily read 240 on the PCB as far as i'm able to trace it.
When I opened up the controller I was surprised to find a little bit of water, and the clear smell of burnt electronics, which in my opinion, is Pentair's fault and responsibility, but of course once I called them they were very quick to tell me that the original installer did not register the equipment in the first 90 days ... so even though the pump is less than a year old, i'm basically SOL.
Being that it's going to cost $600 just for another controller, and because i've built numerous PCBs in my day, there may just be a way to fix this by replacing a component ... but here in comes the issue, I can't find any information online about these controllers (besides programming them), and i'm hoping someone out there can help me out.
So the manual says that the power failure error is because it detects that less than 170v is being supplied to the controller.
My first question is, I noticed the wiring diagram for EU at 120v ... does that mean the pump could be ran at 120 or 240? I would like to put it on 120 to see if that changes the error message, but not sure what these pumps actually support.
Second question, does anybody have any experience at all in troubleshooting, reverse engineering, or disassembling these controllers? Any information would be helpful as all I can find is the standard pump manual online.
It looks like they built the controller so the capacitors are sealed to the housing to act as a heat sink to dissipate heat from the components.
Any help, suggestions, or comments are greatly appreciated! Thanks!!
