  1. why would the motor voltage wire need to be moved to 115v instead of 230v when the motor is stated as being able to handle both? clicking noise on 230v setting. the wire that goes to the overload protector (white wire) is too short to change the voltage setting by moving the jumper. jrivet@satx.rr.com

    1. In short, because that is how they are designed. So yes, a motor is rated as a dual voltage, which means it can accept either 115 or 230, but you still have to make sure it is set to the range you’re using.

      If the wire was too short to switch, I’d classify it as defective. Contact the customer service of the company you purchased the motor from, get a new one. Or, you’ll need to rewire the circuit for 230 voltage.

  2. We just had a new pump installed. It works however the manual says to make sure when the pump is running the light is on green. Well the lights such as speed, on, and start/stop all 3 of them the lights stay on red. Also after the pump runs for 7hrs ea day there is still some fine dust or whatever it is floating on top of the water. You can not see it well but it’s there. What could cause all of this. Any help would be greatly appreciated. Thank you.

    1. What is the make and model of your pump? The series of lights illuminated can mean different things for different pumps.

      That silt could be pollen. We are in Florida, and it is everywhere currently.

  3. Hi. Had to remove the electrolyser today. Closed all valves to do this, then reopened all valves except, by accident and stupidly, the multiposition valve. Switched the pump on and it promptly just hummed. Switched it off fast, repositioned multiposition valve to “filter” and tried the pump again. Just hummed again. Took pump out and examined it having separated it from the filter holder, Impeller turns but do not know how to make sure the pump itself is turning. Can you help

      1. Low voltage or the motor is set to the wrong voltage for what it is set up for?

        It helps to do some troubleshooting of the wiring before so we can at least try to dismiss some possibilities.

  4. The blog post is informative. It offers tips on how to keep the pool motor in great shape. Something I always wanted to know. Thanks!

  5. Great stuff, keep it comeing. Also, looking to receive my pentair filter hopefully soon.
