Needed help identifying the cause and solution to a problem that occurred with my dishwasher plug. I noticed that the dishwasher was not turning on. Upon inspection of the plug connection it looked like the plug from the dishwasher had melted in a way that now was preventing the pins from inserting fully into the receptacle plug.
I have shaved off some of the melted area with a utility knife but have stopped using the dishwasher.

And this is why dishwashers are required to be hard-wired in Michigan. They use a lot of power, so they are subject to this kind of thing happening if one of the prongs fits loosely in the receptacle, creating high resistance and heat. Run a separate 20A circuit from the breaker directly to the dishwasher, and hook it up in the built-in junction box.

Michigan is probably in the minority of states that require dishwashers to be wired in directly. Most states now require them to be connected with a plug so that there is a local disconnect when working on the appliance.

OK, well, if you must use a cord, then use at least a 14AWG one and a higher quality receptacle. That is, use a $3 one, and not a standard 50-cent one. Those will hold the plugs in more securely.

Was the cord on the dishwasher new? Maybe someone put an undersized cord that is overheating. As others have said hardwire a receptacle close to dishwasher on a dedicated circuit. Use a commercial grade receptacle not the cheap ones. They have better connections. Then ensure at least 14AWG stranded wire in the cord and put a commercial grade plug on it.
