E16
          The E16 error code on a Bosch washing machine indicates that the door is not properly closed. This could be due to a number of reasons, such as:
- The door is not shut all the way.
 - There is something obstructing the door from closing, such as clothing or debris.
 - The door lock is malfunctioning.
 
Here are the steps you can take to troubleshoot the E16 error code:
- Make sure the door is closed firmly. 
- Push the door shut until you hear it click.
 
 - Check for any obstructions in the door. 
- Remove any clothing or debris that may be preventing the door from closing properly.
 
 - Open and close the door again. 
- Sometimes, simply opening and closing the door can reset the lock and clear the error code.
 
 - If the error code persists, unplug the washing machine and wait for 30 seconds. 
- Then, plug it back in and try starting the cycle again.
 
 - If the error code still appears, consult your Bosch washing machine manual or contact Bosch customer service for further assistance.
 
Here are some additional things to keep in mind:
- The E16 error code is a relatively common problem with Bosch washing machines.
 - It is usually a simple fix, such as making sure the door is closed properly.
 - However, if the error code persists, it could be a sign of a more serious problem with the door lock or the control board.
 
I hope this helps!
