I had an appliance repair person come out to fix our dishwasher ($$$), he told me this would happen again if I repaired it, and I should just buy a new one. Instead, I bought the component online and DIY'd the fix instead of paying him another $200. The component failed a month later, just like he predicted. I bought a new dishwasher, after spending hundreds to repair my existing one.

Moral of the story: hubris is expensive.
