I've notice a problem within the last two weeks. My Ecostar pump has been shutting off with the LCD reading that it has lost prime. The pump is less than two years old. The only way I can get it to restart is to cut the power for a few seconds, open the lid, then closing it again. The problem though is that the pump is full of water when it shuts off. I would have though that if it lost prime, there would be very little water in it, or at least some air. But no, it's chock full of water. Any ideas on this? Thanks.
