Our power surges caused our dishwasher failure. They have also taken out a range and two TVs. I am too cheap to put a surge protector in our main panel.
After the washer blew up I bought an outlet surge suppressor just for the washer.
The $40 dollars seemed like cheep insurance.
Then a few years later I had to replace the main breaker box after a tree falling took out the drop line on my house so I had a surge suppressor put on the new box.
