Bosch dishwasher smells burning rubber

Check the drain pump. First, manually initiate drain by pressing the second and fourth buttons on the keypad at the same time. If it pumps out, disregard the rest. If it doesn't at least hum, check for power at the motor.
Remove lower rack, lower spray arm, and screens in bottom, remove all water inside. Check for debris under pump cover in bottom of sump. The drain pump suction is through the hole on the left.
Behind the toe panel on the left is the drain motor, If no debris was found inside, the drain pump may have failed. Remove outer door panel (you may need to remove the two screws on the sides of the control panel.) Remove the metal panel across the top of the motor area , disconnect hose in front of pump, disconnect wires to pump, press tab at top of pump and rotate clockwise to remove pump. The impeller could be loose on the motor shaft, or the motor windings failed.

probably is, hit the breaker

The motor may be burned out or there may be another electrical issue which would also cause the symptoms you describe. Call around and try to get an estimate, and at the same time look at new ones on sale.............one question is how secure will u feel with that maching......now that it has acted up like this.

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.
