Detach the pool pump from the filter by removing the hose clamps that are connecting the two. Also remove the hose that attaches the pump to the skimmer. Make sure that you have attached the plug to the skimmer wall before detaching the hoses, or you will lose the water in your pool.
Drain all of the water out of the pool pump. Tilt the pool pump upside down so that the water can drain out. It is also a good idea to tip all of the hoses so that they are void of water before storing.
Open the pump housing with a screwdriver. Use your hands to remove any hair or debris that may be tangled around the motor. A buildup of any type of debris inside the motor can cause it to burn out unexpectedly.
Wipe down the motor and common areas with a clean rag. You can use a damp rag, if necessary. It is important to remove all traces of sand, earth or gunk that may have built up around the motor over the swimming season.
Replace the pump housing and screws. Store the pool pump in a dry, out-of-the-way area for the winter. This could be in a shed, basement or garage, where the pump will be protected from the freezing weather.
