Samsung WW80K5410UX stops after start attempt with flashing door lock symbol

The problem

Samsung WW80K5410UX front-loading washer would not continue a cycle. On start-up, the AddWash door lock clicked around six times, the machine then began its normal start-up noise, stopped after about 10 seconds, and flashed the red door lock/key symbol.

Likely cause

Most strongly supported diagnosis is a door latch/door lock actuation issue, a wiring/connection problem to the lock, or a control board fault. The exact failed part was not confirmed. The original poster had already replaced the main door lock without curing the fault. A capacitor on the board was noted to have softened surrounding silicone, but no confirmed link to the fault was given.

What fixed it

Recommended action was to check that the door latch was intact and correctly operating the door lock. If the latch, lock and associated connections were sound, the accepted reply indicated the fault most likely lay on the control board. Exact repair was not confirmed in the thread.
