Hayward EcoStar Pumps
EcoStar is a line of Variable Speed Pumps (VSP)
The EcoStar pumps use a three phase motor with a variable frequency drive that converts the power from single phase into three phase at the right frequency.
Consider the Hayward TriStar VS Pumps as a replacement for a failed EcoStar pump.
DRIVE ERROR - PUMP HAS STALLED error
We have seen that failure for the EcoStar many times in the past couple of years. The control head dies. You can replace the control head but it is almost the same price as the whole pump. There are plenty of threads about it, but not solutions.
Some members have reported having positive results by calling Hayward. They know about the SP3400VSP pumps issues, and have been offering up replacement parts, and/or huge discounts on a new pump. Give it a try
Diagnostics
Remove the Blue, Black and Red wires from the drive and check each motor lead to ground.[1]
There should be no continuity.
Next, check continuity from lead to lead. Ohms reading should be between 0.5 and 1.0 ohms max.
If any of these readings are outside limits, replace motor. If they are within range, replace drive.
Freeze Protection
The EcoStar does not have built in freeze protection. It does have a low temp setting that only keeps the drive at or above the low temp set point. It is not intended to protect the system from freezing.[2]
Low Temperature Operation
Press menu, press and hold < > and it will unlock configuration menu. Press > till you get to “low temp operation” it takes more than 7 presses to get to it. There you can enable or disable. I think the next press will get to the speed it will run at. Press again and you can set temp.[3]
