How do I fix error code DC on a Samsung washers?

1. undefined: 1. If DC/DC1 error occurs, check whether it occurs during the Boil cycle 2. undefined: 2. If it is detected that the door is open, close the door 3. undefined: 3. Check the door switch — 120V is connected directly to the door switch 4. undefined: 4. Check Reed S/W resistance: checking part White-Green wire, resistance approximately 0.2 ohms 5. undefined: 5. Check Door-Lock S/W terminal connections and contacts 6. undefined: 6. Bring probe of tester into contact with two terminals of Door-Lock S/W (checking part: Black-Brown wire) 7. undefined: 7. In state of door close (DC error): resistance should be 34 to 51 ohms 8. undefined: 8. Check Reed S/W resistance between terminals of Door-Lock S/W (DC1 error): checking part White-Green wire, resistance approximately 0.2 ohms 9. undefined: 9. Check Lock/Unlock motor resistance: checking part White-Red (Lock), White-Blue (Unlock), resistance approximately 0.2 ohms 10. undefined: 10. If resistance is satisfied with spec, replace the PBA

Error Code DC

Q: What does error code DC mean on a Samsung washers?

The washer door is not locking or unlocking properly Switch contact error because of a deformation of the door hook; Door is pulled by force; Door is pushed during Boil wash due to pressure difference from internal temperature changes; Door switch fault; Main PCB fault

The washer door is not locking or unlocking properly

Moderate

Address soon - your appliance may not work properly

Also displayed as: DC (upper) / DC (lower)

What This Means

Switch contact error because of a deformation of the door hook; Door is pulled by force; Door is pushed during Boil wash due to pressure difference from internal temperature changes; Door switch fault; Main PCB fault

What actually causes this:

The door was not pushed closed firmly enough, or the door latch mechanism is worn out

First Thing to Check

Push the door firmly closed until you hear it click — make sure nothing is blocking the door

1. If DC/DC1 error occurs, check whether it occurs during the Boil cycle
2
2. If it is detected that the door is open, close the door
3
3. Check the door switch — 120V is connected directly to the door switch
4
4. Check Reed S/W resistance: checking part White-Green wire, resistance approximately 0.2 ohms
5
5. Check Door-Lock S/W terminal connections and contacts
6
6. Bring probe of tester into contact with two terminals of Door-Lock S/W (checking part: Black-Brown wire)
7
7. In state of door close (DC error): resistance should be 34 to 51 ohms
8
8. Check Reed S/W resistance between terminals of Door-Lock S/W (DC1 error): checking part White-Green wire, resistance approximately 0.2 ohms
9
9. Check Lock/Unlock motor resistance: checking part White-Red (Lock), White-Blue (Unlock), resistance approximately 0.2 ohms
