Eventually, your submersible pump is going to drop in performance as you'll generally notice when the waterfall flow begins to lessen. For the most part, it's not a direct issue with the pump itself but rather debris blocking the intake.
Below we'll breakdown in a few easy steps how to disassemble and clean your submersible mag-drive/asynchronous pump.
Before anything, check your power supply. An obvious statement, but make sure the pump is still plugged in. If it is, make sure the GFI is not tripped and test the pump on another outlet. Move down the power cord and check for cuts or tests.
Unplug the pump, disconnect tubing from discharge and remove from the water. Obstructions can stem in few areas but generally they're found on the suction end. On most pumps you'll find a removeable prefilter and on some you'll even find the pump is encased in a 2-piece outer cage. Remove these and let's get started.
After prefiltration is set aside, we need to remove the impeller cover. Some twist off, most are held onto the body of the pump with a few Philips head screws. After the cover is off, carefully slide out the impeller/rotor.
With everything laid out, using a soft bristle brush, clean all components thoroughly using a diluted solution of white vinegar or CLR. After cleaning, go ahead and reassemble.
Afterwards, don't connect the pump to your tubing just yet. Submerge alone, plug in and test for a few minutes. This way we can eliminate the variable of any obstructions in the tubing or inline filtration. We recommend doing these cleanings at least twice a year to extend the life of your pump.
