Pentair pump alarm says overcurrent.How do I fix or reset to get my pump running once again.pump was running fine ?????

Check incoming voltage umder load. if its under nameplate volts when running you have overcurrent. check fan inside housing for damage or blockage. finally check disch pressure to make sure no restriction blockage in line. Im Pentair engineering person

the power failure alarm is there for a reason.

check incomming voltage was pump wired correctly see diagram on side of motor

No.
there is no reset button, that you can manually press to reset it. There is an internal "thermal overload switch", which is an automatic reset. So if your pump motor is overheating, it will turn off, but once it cools down enough, it will reset automatically.
some styles of the Dynamo, have a toggle switch at the back underneath, which is simply an on and off switch.

turn off breaker to pump for a few minutes, then back on this will reset your alarm. If the problem returns ,check other posted solutions. In a few weeks i may have location of someone who repairs circuitboards for pentair pumps, as i am having one repaired now due to lightning hit.

The motor on the pump likely has a shorted turn or turns. If the motor is still under warrantee then you are in luck.

I hope this helps.

To protect the IntelliFlo pump electronics from damage due to freezing conditions, the pump will switch itself on to generate internal heat when the air temperature drops below 40° F. This feature is not intended to protect the system plumbing from freezing. The pump will run at a lower speed than what you have it set, unless you have programmed the adjustment.
The Intelliflow pumps are great pumps, but come at a disadvantage- A whole lot of electronics.; Since the intelliflow pumps are fairly newer in the market, and you have already had the electronics replaced recently, so I am going to presume that you still are under Pentair Manufacturer warranty.
The issue you are describing remains a problem with the electronics. Since you are not getting any alarm codes, there may be in issue in the wiring or you may have a defective pump. Before calling into the manufacture, lets reset the pump to factory defaults:
The IntelliFlo VS-3050 pump can be reset to the factory default settings. All previously adjusted pump speeds that were saved will be erased. To reset the pump to the factory default settings: 1. Ensure that the pump is powered on and the green power LED is on. 2. Press the Stop button to stop the pump. 3. Press and hold all of the four Speed buttons simultaneously for four seconds. Power off the drive and reenergize. The default settings will be in effect.
If this solves your issues, then you can program the pump to operate at the desired time/speeds.
If you are still having issues, I recommend contacting Pentair Warranty at 800-831-7133. Be sure to have the date of install, the Serial and Model numbers handy when you call.
