I have a Hawyard wide mouth skimmer and the weir does not go down when the pump turns on, so I can not put my pump on auto mode until I fix this problem. The door does not seem to be really stuck, because when we swim, just gentle ripples cause it to open and close. I've searched old posts but I don't have a rock stuck in there, my foam seems to be in the right place, the only plastic that is touching the skimmer are the two hinge tabs that hold the weir in place, I don't have the door on backwards, so I'm still confused- please help.
