Hello
I am having a very similar issue to what is referenced here:
www.troublefreepool.com
I am getting random breaks in communication between the intelliflo pump and easy touch controller. The pump display goes back to showing the rpm and I can not control it via the app or panel. If everything is power cycled operation returns.
This happens in random time intervals. I performed the service mode check and the pump stays on switching from display not available to the rpm display.
I also tried various combinations of the pump breaker off or controller off to see if the communication would not re-establish but I could not reproduce the issue.
It seems like the rs485 transceivers are locking up or going into an error induced time out.
Any help would be greatly appreciated.

Hello All, I have been reading and searching for the solution to my problem and have tried most of the fixes to no avail. So... here's the problem, recent history, and what I've done to date. My Intelliflo VS pump from the original build in fall of 2016 started to get noisier and noisier...
