Hi Christine
These are great machines when they work properly, when they don't, well they are very difficult to diagnose, so you may end up having to replace some parts on speculation.

Before doing anything like spending money I would say let's start by completely cleaning out the drain system. To do this you will need to lay the washer on its front to access the drain pump and hoses.

Here is the service manual which will show you how to do that, along with some info on your error codes and what they mean. After you drain out the system and check for any obstructions in the drain/pump/tub, put things back together and see how it does.
