Clogged drain pump filter (most common for Samsung, LG, Whirlpool, Bosch, etc)
All washing machines have a water drain pump that is designed to evacuate the water from the tub after cycles of washing and rinsing the clothes.
However, if during one of these draining cycles you hear that the pump appears to be running but water is either going down slow or not at all.
Chances are there might be a clog in the pump filter that is restricting or completely preventing the water from going through the pump.

So, the first thing you need to do is unplug the washer from the outlet and pull the washer away from the wall so that you can gain access to the back panel if the drain pump filter located behind the machine, but on the most of the front-loading machine filter located on the front.
Remove the access panel and locate the drain pump and remove the hose from the inlet side and check the filter for any debris that might be clogging it.
If you find any debris, clear it all away and reattach the hose.
Button up the back access panel and plug the washer back in and check to see if it drains properly.
