Could a failing Door Lock Switch Assembly cause the SAMSUNG WF45R6100 to have symptom: Door Wont Unlock?

This electromechanical component uses a bi-metal heater or solenoid to engage a physical locking pin. Failure occurs when the internal PTC heater burns out or the mechanical slider binds, preventing the pin from retracting at the end of a cycle. It is the most frequent failure point for doors that remain physically locked despite the cycle ending.

Could a failing Drain Pump Motor cause the SAMSUNG WF45R6100 to have symptom: Door Wont Unlock?

The control board safety logic inhibits the door unlock sequence if water is detected in the tub. If the drain pump impeller is jammed or the motor has failed, the standing water keeps the pressure switch engaged, forcing the door to stay locked to prevent flooding. Replacing the pump restores the machine's ability to reach the 'dry' state required for unlocking.

Could a failing Door Latch Strike cause the SAMSUNG WF45R6100 to have symptom: Door Wont Unlock?

This is the plastic hook attached to the door itself. Over time, the hook can become misaligned or develop stress fractures, causing it to catch on the internal mechanism of the door lock assembly. If the strike is bent or broken, it will physically prevent the lock assembly's slider from moving to the 'open' position.
