Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am APPLIANCE-HVAC GURU a very experienced tech on here and I try to get to as many customers as I can. I just picked up your question now.

Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and did not receive that money.


When that happens you need a new pump control board. The board has a voltage monitoring chip on it that has failed. Replace the board and you will be good to go, they sometimes fail that new I have seen it before.

The only way I receive any credit at all for my time is by you selecting a STAR USING THE 5 STAR or VOTING RATING SYSTEM AT THE TOP OF YOUR PAGE before you leave for me so please make sure you are rating me not another tech. If you are not happy with the service please let me know before leaving a negative rating. This will also allow you to get directly back to me for FREE follow up questions and tips are greatly appreciated! Thanks GURU

Not the problem. I played around with pump solar / filter speeds and problem solved. Parameters were too far apart!
Thanks for your time
