Thanks for contacting
. I understand how frustrating it is having trouble with your appliance not working.
With the e04 error code the washer stops and keeps the door locked because the unit is over suds or overfilled. If you break the door lock the washer may flood your wash area with the water trapped in the basket. The release of the door lock is such that the top and the control board panel will need to be removed to get to the release line that is attached to the drain pump hose. I understand you problem but the chances of a major spill are present and I would recommend you wait for the technician out to check the washer.
Please feel free to let me know if you need further assistance. We are always here to help.
