I have a bwm 50 washing machine displaying e2

The e2 error is a generic error that the machine shows if it's been overloaded or if the load becomes unbalanced during a wash cycle.

To fix you must do a master reset of the washing machine.

1. Close the door and make sure the dial is pointing to the "OFF" function
2. Hold the Start/Pause button and turn the dial anti clockwise (to the left) to the "express 15 min" program at the same time.
3. Hold the Start/Pause button for a minute (the e2 message is meant to start flashing after a minute of holding the button down however with my washing machine this didn't happen) (and neither with mine)
4. Release the button and turn the dial back to the "Off" function.
5. Select any program and the message should not be appearing

Hope this helps
Bob
