Hi! I'm hoping someone can help me, I've got a clog somewhere from vacuuming leaves....I know stupid! I've read all the posts I can find on this and have determined from them that the clog is before the filter since the psi is almost nothing. The pump chamber fills only about 1/2 way and the water from the main and skimmer comes in somewhat slower but not terrible. It fills up a little over half and then the pump sucks it up and then stops to let it fill again....kind of a pumping action. When I turn it off it fills almost full but I think there is water coming back from the filter. No suction from the skimmers, barely any output from the jets. The pump chamber's leaf basket had a small crack on the edge that I didn't know about. Leaves were jammed in the crack. I reached up and felt the ocillatior and it was clear. The 0 ring is fine, I lubed it just in case. No leaks in any of the connections. I was able to look at the tube from the motor to the filter and it was clear. Not sure if it can get stuck somehow in the valve on the filter or how to take that apart (sand filter). I plugged up the skimmer that I didn't vacuum out of and shut off the main and ran a garden hose into a funnel into the line to see if there was a jam there and water came out the supply line in the pump, so I don't think that's blocked. Where the heck else could it be??? Maybe I burned up the pump, but it sounds the same. Thanks so much!!
