Those drivers definitely fail; I had a board where they got super hot. To desolder a DIP just snip the leads off and then desolder the pins one at a time.

Note you can update your AquaLogic firmware if need be: Anyone tried uploading / downloading firmware from Hayward GLX-PCB-MAIN boards? I did this when I installed a TriStar VS pump. But if you're set on the Pentair you'll have to swap out the AquaLogic as well to get full control over the pump.

I want to add a variable-speed pump but the firmware on my board is too old to support it. So I contacted Hayward; apparently they have a field service tool that can update the boards, but none are available in my location. Good news is the technique described above works great. A friend of...

Same problem here. Not my sig and it won't let me edit it.

I don't know about the SP2302VSP motor control protocol, but the Aqualogic/Prologic protocol doesn't appear to have a master/slave arrangement. I'm guessing they do collision detection instead (what I've discovered so far is documented here).

Nice find! I've got a couple of GLX-PCB-MAIN boards, but they are both running v2.6x. I'd be interested in trying to update them. I think some of what you want to accomplish could be done with external automation. @draythomp has done a bunch of work to decode the Goldline protocol. I plan to...

The diffuser is on correctly; I've had the pump apart about a dozen times trying different things. I did run the motor when disassembled and did not notice any wobble, but perhaps I should check again. I'd be really surprised if I actually managed to bend the shaft; perhaps the impeller is...

Took a closer look and it does seem like the pump output is reduced without the impeller ring. I guess I must have bent the shaft somehow during the bearing change (the impeller was really stuck and required a great deal of force to remove). :cry: So I guess I'm in the market for a new motor...

I just replaced the bearings & shaft seal in my Hayward Northstar pump. Put it back together and the pump was making a noise like this: [youtube:2tsah87d]flY03WsMxsE[/youtube:2tsah87d] (this isn't my video, but the pump was making the exact same noise) Removed the impeller ring and the noise...

Yes, it is a steel-wall/concrete bottom vinyl lined pool (Kafko to be precise). There doesn't appear to be any separation, but of course the join is hidden behind the liner. I really don't know how else so much debris could be getting in there. I guess the pool will have to be partially...

I have a 6-year-old vinyl liner pool. For some reason I am getting sand and gravel in between the liner and the pool walls (you can readily feel it with your hand). Seems to get worse every year. The only thing I can think of is the winter freeze/thaw (I'm in Ontario) has separated the...
