Hello, my ~8 year old Pentair Intelliflo is showing a Alarm! Priming Dry error. The pump doesn't sound like it's trying to prime at all. It doesn't make a sound. The rpms and watts will rise until it times out, but no sound. I'm running it via a Pentair EasyTouch control system. I can manually move the impeller by reaching in past the skimmer basket. Any ideas on what else to try?
