8E2 FAULT CODE

repairman15,
For your model and that error it states that there is a communication error. You’ve already replaced the two ‘logical’ parts being the sensor and control. I would double check your harness plugs and connections and look for damage to the plugs/connectors on the control and sensor. If those look fine, next thing I’d check is the actual wire harness itself and look for any signs of damage. Finally if all of this passes the “eye” test, I would remove the harness from the sensor and the control board and ohm the wires out. I just returned from a Samsung training class, their rep stated that they’ve had issues with their wiring breaking inside the coated wires but not breaking completely for you to physically see it broken. They said that this type of failure is extremely difficult to find because in order to find it you must check the wires for continuity while flexing the wires in “just the right spot”. The rep said that in a circumstance such as yours that it would save sanity to just replace the harness entirely.
I hope this helps in some way
