Error Code DC

The washer door is not locking or unlocking 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

First Thing to Check

Parts Involved

How to Fix

1. 1

   1. If DC/DC1 error occurs, check whether it occurs during the Boil cycle

2. 2

   2. If it is detected that the door is open, close the door

3. 3

   3. Check the door switch — 120V is connected directly to the door switch

4. 4

   4. Check Reed S/W resistance: checking part White-Green wire, resistance approximately 0.2 ohms

5. 5

   5. Check Door-Lock S/W terminal connections and contacts

6. 6

   6. Bring probe of tester into contact with two terminals of Door-Lock S/W (checking part: Black-Brown wire)

7. 7

   7. In state of door close (DC error): resistance should be 34 to 51 ohms

8. 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

   9. Check Lock/Unlock motor resistance: checking part White-Red (Lock), White-Blue (Unlock), resistance approximately 0.2 ohms

10. 10

    10. If resistance is satisfied with spec, replace the PBA
