Neptune ATK issue

[Intheflesh]

I'm wondering if anyone else has this problem.

So I noticed that both SWX in apex was stuck in a closed position, and ATK was never turning on. This resulted in me forcing ATK into "ON" from "AUTO" until the timer forces it back "OFF"

Eventually, I just replaced the optical sensors, and this seemed to fix the issue. Now I seem to be having a separate issue. When left in "AUTO" and both sensors are OPEN, the pump will kick on momentarily, then cycle on/off/on/off a couple times until it will run continuous for about 30 seconds then shut off, and then eventually will turn the mode to "OFF" in apex.

TL;DR version: When left in Auto mode, my ATK will cycle on/off a few times, run for a little bit continuously, then shut off, and turn the mode to "OFF" in Apex. I have it programmed to turn "OFF" after 5 minutes, but the pump is never running that long.

I'm wondering if there's something in my code that's doing this or if maybe I have a faulty FMM unit.
Here's my code, which I'm pretty sure is just the basic, preloaded code:

Fallback OFF
Set OFF
If Swx5_1 OPEN then ON
If Swx5_2 CLOSED then OFF
When on > 05:00 Then OFF
defer 000:10 Then ON
Defer 000:04 Then OFF

Where is the FMM’s external power adapter plugged in? If it’s in an EnergyBar output, be sure that output is configured for Always ON. Better yet, move the power adapter to a regular power strip.

If that’s not the issue, try the troubleshooting instructions in my ATK tutorial:

Yes, the FMM is plugged into external power. Its plugged into my Energybar into an outlet that is always ON

So I'm attributing this to a bad PMUP (its a V2). I had a spare V1 in the basement, and I switched the two out.
I tried manually controlling the pump in Apex by going through the cycles (ON/OFF/AUTO) and it seems to be functioning as normal. do'h! I do need to get a new pump however, as my spare is unbearably loud.
