b4,
This is my go to information on the eco pump stall error:
Hayward Ecostar drive stall error is unfortunately a common problem with Hayward Eco Star variable speed motors. Drive stall problems are noticed when the pump tries to turn itself on and can not. The pump will “stall” throwing a red light on the control board. The board will also state that it has stalled and that there is a pump stall error.
What to Check First
Hayward has worked on this problem for a while and has been able to bring the amount of drive stalls down on their units. If you are experience a drive stall error on your pools pump motor, take these steps to try and correct the issue first:
•Shut down the power to the pump from the breaker for five minutes – turn back on and try to run the pump.
•Make sure that there are no blockages in the impeller because the motor will not turn if the impeller cannot rotate.
•Make sure that the drive is bonded and all four tightening screws are secure on the drive.
When running through all these checks and balances if it is noticed that there is not bond wire or that the tightening screws are not all secure, correct the issue. Attach a bond wire to the Eco star drive pump or tighten the loose screws on the bottom of the motor. When this has been corrected, shut the power down to the pump and rest it after five minutes. Check if the pump will now run.
This Still Did Not Work
After checking these items if the motor is still saying drive stall error, it probably means that you need a new drive. Check the serial number on the pumps sticker. Hayward offers now a 4 year warranty on these drives. If you have had the pump less than four years you can file a claim on the drive for a warranty.
Good luck,
