Because I felt overran with laundry I packed a bit too much into the washer and boy was that a bad idea. It shut itself off and would not run the reason: the washer was overloaded
In order to make sure this does not happen (something that I all ready knew but relearned) I learned to pile clothes loosely. Stuffing clothes into the washer not only does not allow them to get clean but may overload the washer (which it did)
What did you learn or in my case relearn?
