My washer is not draining water pretty sure its clogged. Not 100% though how do I fix this problem thanks

What kind of washer? Top load take off and flip backwards the selector board. It should expose some screws to lift top up and of the washer off. There are also some screws that should be on the sides that allow you to remove the front of the washer. That will get you to the plumbing of the washer. Just look for the line coming out of the bottom connected to the water pump/motor. Just depends on what style of washer you have.
Front load washer... post again if you have a front load washer that is a bit more involved but I'll do my best if you need help with that... I've owned both.
