What causes a door error on my Samsung WF42H5200AW?

A door error on your Samsung washer can arise from several issues. These include a switch contact error due to a deformed door hook, pulling the door with force, pressure differences from internal temperature changes during a boil wash, an incorrectly connected or broken door lock switch terminal, or an electric wire leakage. To resolve this, check and repair the door hook, avoid pulling the door with force, ensure the door can operate freely, reconnect or replace the door lock switch terminal, and inspect for and resolve any electric wire leakage. Also, the main PCB fault can lead to this error, in this case replace the main PCB.
