Did you know your washer has a built in nurse and your job to be the DR.?
What do I mean?
All washers created after 2012 have what's called a diagnostic mode which is a program inside the washer control board that can test itself for fault.
In other words: Your washer will tell you what's wrong so you can do the fixing!
NO GUESSING!
Before even getting tools run the self diagnostic & calibration mode mode so you know exactly what's wrong.
