Pool tech says he thinks it’s an issue with the pump. Guess I’ll call Pentair and see what they say.
Pressure drops inexplicably

One advantage of buying local is they "should" help you if it's bad..In case they give you the ole " box it up and ship it to us" Crud
Based on the issue with the previous pump, I would suspect a power quality problem.
I would want to put a power monitor on the line to see the voltage, amps and power usage over time.
I would want a data log to see what happens over a 24 hr period.
Either that or I would put a resistive load on the line and watch the voltage for a while. I would use a 240 stove element about 8" and 2,000 watts. You can check the amps as well to see if they fluctuate. Of course the element will get hot, so you have to rig up a safe test site.
Or, check all of the breakers and wires going to the pump.
Have an electrician check it out if you're not sure about it.

I called Pentair about the error codes. They ended up saying to open it and check for anything blocking the impeller. So I opened it and found this.
The stupid pine needles again! Not only that but there were cracks around the diffuser and one of the nuts pressed into the sealplate came right out with the screw.
Pretty sure that’s not right and I can’t imagine the pine needles caused it after only a month. I feel like the more likely thing was that the stuff was damaged to begin with and the pine needles got under it because they were able to.
So I guess I call Pentair back and ask for a new diffuser and sealplate...

Was there enough debris to impede the impeller?
Is the basket installed correctly?

Basket is fine, only fits one way. These things just slip through it because they point the direction of the water flow. We end up with a ton in our filter every year. Hard to say if the impeller was impeded but I can’t imagine it was spinning well with pine needles pressed between the diffuser and seal plate against the impeller.
We have hairnets on order to act as skimmer socks.
The controller will reduce the rpm to protect against excessive amperage.
So, maybe the impeller was being restricted by debris and causing the amperage to go too high.
The problem with the previous pump still points to a possible problem with the power supply, in my opinion.

I feel pretty sure that the problem with the old pump was pine needles getting between the impeller and the diffuser and opening up the plastic to prevent good suction/push.
Ok, hopefully, the problem is resolved.
If it continues, I would rig up a voltage and amperage meter that can log the readings over time to see what's happening.

Also can’t hurt to make sure all the screws are tight where the wire slides in while it’s off

They were. So not sure why that error popped up.
Pentair is sending a new diffuser and sealplate (along with their seals, presumably that means the o-rings). I'll put those in once they arrive.

Parts came in yesterday. I swapped out the sealplate and the diffuser. Now it seems to be working well.
Pool was a bit hazy when I removed the solar cover, but it’s been on all week. Took FC to slam level, gave the whole thing a nice vacuum and brushing. By tomorrow it should be better. If not I’ll keep up the SLAM.

Pool is clear. Pump is working great. Skimmer is really skimming...I emptied it last night around 7pm. After 13-14 hours, I had this in the basket completely restricting flow.
