Is there anything else you need to do after cleaning cartridge filters and putting everything back together before turning the pump back on after 5 minutes there was still no water moving?
You must purge the air out of the line that sucks the water out of your pool(inlet to pump side).This is usally done by opening a bleeder valve on top of the filter cover. #1 Shut inlet and outlet valve to pool. #2 Clean or change filter and re-install lid. #3 Open pool line valve on inlet to pump side. #4 Open bleeder valve on top of pump until only water comes out,then close bleeder valve. #5 Open pool valve from (pump to pool side) outlet to pool side. #6 Turn pump back on. Running your pump without water for more than a few seconds can damage or burn up your pump.
