I'm trying to figure out what happened to this pump. It's a Waterway 1.5 hp single speed pump. It ran well for 5 months. The pump was plugged into a timer on a 50ft 14g extension cord. There is a multi-outlet port with built-in breaker with reset button that the timer is plugged into. When checking pool a few days ago, I noticed pump motor not running. I reset the breaker and turned pump motor back on. It ran for 5 seconds and tripped breaker. Also did not sound right while running. Received replacement motor under warranty. Installed it and ran it plugged in without timer in place. Ran fine. Turned it off after about 2 minutes. Placed timer in line and turned pump motor back on. Immediately ran with same unusual sound as previous motor and tripped breaker. Removed timer. Turned motor back on and now makes unusual sound and trips breaker every time I attempt to run it. I have a third motor, but am reluctant to install it until I figure out what has happened with the previous 2 motors. I have attached a link to a video of the second pump running until breaker is tripped. Any ideas would be greatly appreciated. The link: http://youtu.be/5-MzOINvS0g
Update: Just out of curiosity, I turned on the original pump motor that had problems and it ran fine. So now I'm really scratching my head. I will post a link to this one running normally for comparison to what the current pump sounds like. The link: http://youtu.be/9164tZj-KXQ
