When you go to start your pump, you may run into the issue of it simply humming and not starting. Do not worry; you are not the only owner in the world who will (or already has) experienced this issue. Thankfully, there are some quick troubleshooting tips that you can perform that should fix the issue. Probably the most common, though, is there may be debris that is clogged within the impeller.
To see if this is indeed the issue, begin by removing the screws in the body of the pump to gain access to it. From there, pull the assembly out of the housing and then also remove the gasket. You should now have access to the impeller and now you can remove any debris that is caught inside. After you have removed it all, go ahead and re-assemble the unit and try to start it again.
