At random times, my Intelliflow VF shuts off for a couple minutes, then resumes automatic program.
This occurs totally at random and does not happen when observed for several hours (longest time I've been working on wall project near pump for 4 hours, it did not happen).
Today, for example, happened to be brushing pool and pump turned off, power was not lost and there was no voltage "blip" at house as I monitor power quality with a TED5000 unit (Low Voltage Today:234.4 V @ 11:34 AM)
The pump resumes normal program in one minute.
Filter is clean (rinsed off 2 days ago), all equipment is new, no blockage, PSI is at 0 when running, about 4 PSI when priming).
Pump runs 4 days a week 2 programs, one for 4 hours at 20 gpm, another at 6 hours at 15 gpm.
The other days pump runs 24 hours at about 10 gpm.
