Soapy water leaking from bottom of dishwasher door

The dishwasher was running perfectly, but over time it leaked more and more. We were ready to throw it out, when I searched the internet and saw stories about a tiny gasket commonly failing. I couldn't believe that could be the trouble, but ordered the $3.75 part. Unscrewed the door, slipped out the old gasket and slipped on the new one. Screwed the door back. And the result? THE LEAK IS FIXED! Unbelievable. The old gasket had gotten stiff, probably exposure to soap, and it wasn't sealing properly. That $3.75 part saved us hundreds and hundreds of dollars and will give us extra years of use from our dishwasher.
