SunSun 704B Canister Filter Impeller Issue
I have a SunSun 704B canister filter and it is malfunctioning. The impeller will not work when I put the impeller cover on it. When I test just the filter top, I can get the impeller spinning but when I put the impeller cover on, it usually stops. Sometimes it will work after I put the impeller cover on but if I turn it off then on. it will not restart. I have to take the impeller cover off to try and restart it again. Any assistance in rectifying this problem would be greatly appreciated.
