Bosch Dishwasher Classix

I've had the same problem TWICE. It seems the natural vibration of the machine loosens wire nuts and leads to the problem. Soldering the connection and then placing a yellow wire nut over the soldered connection works fine to stop the problem. This machine has a electric water heater to sterilize the dishes and draws a lot of power, near the limit of the connection, more than a standard dishwasher. I called Bosch twice about this problem, only the second time when I stated that my lawyer might call them back did they admit that there is an issue with the vibration of the machine leading to the wire nut becoming loose and suggested I solder the connection. Great dishwasher, lousy customer service. They have know about this problem for years.

Had similar problem on my Siemens which is the same as Bosh. I started to take it apart to see what had gone wrong. Eventually I had to disconnect the cable going into the washer - its in a small box at the front at the bottom. The wire nut connectors had melted and shorted out. Unfortunately now it won't fill with water. The smell was not like wood so maybe a different problem.
