I was just having the same problem with my filter and after the help I received from this great forum , I filled my pool to above the skimmer and vacuumed to waste. You have alot of dirt/debris in the pool and that is causing your problem. Also after you finally have clear water, take powdered dish washing detergent and make a soapy solution to soak your filter in. Then recharge and you should be good to go , just keep an eye on all your levels.
