When draining, the water is overflowing where the hose is going into the drain in the wall. Is the water draining too fast. It doesn't happen all the time,but a few times a week.

There is a fix for this that seals that pipe. Just look on the internet and you should be able to find it. Look at this: How to Fix Washing Machine Drain Pipe Overflow (http://virginialynne.hubpages.com/hub/How-to-Fix-Washing-Machine-Drain-Pipe-Backing-Up-and-Overflowing)
You may need a bigger drain or to clean out the drain you have now because lint builds up in a pipe and restricts it.
