How to fix a button on a dishwasher?
I had this happen on two different machines. I was able to just use some crazy glue on the one because I had the parts. The other occasion I was missing the parts so I took the spring from a switch on the machine that I never used.. I think it was the "quick rinse" button. If you can't swap out the spring maybe you can swap out the switch or swap the connections. Last but not least, if it's just a simple toggle switch pick up a small one from a home or electrical supply company, hook it up and mount it on the door.
