Sorry for you loss.
The washer problem could have several causes, more detective work will be required. I am not too familiar with this particular model so hopefully someone else will input here as well.
A couple of things you should check first...Open the door & lift the drum up & down to check if there is any slack. Check that the machine empties properly. Post new findings.
Other problems could be: friction dampers (shock absorbers) defective or a counterweight could have worked loose.
