Hayward Maxflo VS Pool Pump Motor Drive Unit Repair - Part 1

[@michaeldauria]

Thanks for posting this! I am having a problem with a similar VS Pump wherein my display shows what the pump is doing, but I am no longer able to control the pump at all. Before i dive in and poke around, I am curious to see how the board goes back in while retaining all of the heatsink abilities

Not sure if you discovered this yet, but the cap that blew was a panasonic 2.2uf 450V. I have a Tristar VS 900 that stopped working a week ago during a lightning storm. Same no power symptom as yours. I didnt check the 12V out on the RS485 port; didnt see your video until its in pieces on my table. I'm digging to find the problem. Nothing obvious yet. Wish me luck

Very helpful, thank you.

Thanks for sharing. That enclosure design seems really be the source of the problem. Have you thought about heat cycling condensation as a source of that water? Sealed enclosure may with drop of air temperature suck air and have some condense inside. After few hundred daily cycles it can make a decent amount of water. It does not explain why one side was clear. Maybe sun makes it warmer there or something.

The source of the leak was discovered. Though condensate would at some point cause that oxide on both sides of the aluminum given enough time if that was the culprit.

Thank you. This is what I was looking for.

Glad I could help.

The integrated power supply board that you showed in your video is the same one I have on my Hayward pump. My board burned up at the power connection and I am trying to find a way to purchase the board. Do you have any ideas? Should I go directly to Hayward?

[@retrotechandelectronics]

I done believe they sell it as a separate unit but you can try.

[@Todayisthebest-ms1qv]

Brand new Hayward vs pump. Dead control panel despite power to unit. Removed back plate and there is a red illuminated light under the green motherboard - even though breaker is off. Any idea?

[@retrotechandelectronics]

Start a troubleshooting regiment if you’re qualified.
