Error Code dE

Door open or door switch abnormal. During normal operation displays when door is opened mid-cycle. In test mode indicates door switch fault.

What This Means

Door not fully latched; Door switch defective; Door switch wiring harness disconnected or damaged

How to Fix

1. 1

   Enter diagnostic mode (Power + More Time + Less Time simultaneously)

2. 2

   Press START/PAUSE once — dryer tumbles without heat

3. 3

   Open door — dE code and chime (7 times) should appear and drum light should come on

4. 4

   If dE does not appear and light does not come on, proceed to mechanical test

5. 5

   Disconnect WH1 and BL3 connectors from main PCB

6. 6

   Measure resistance between WH6 pin 6 (GN) and chassis ground screw — must be less than 1 Ohm

7. 7

   If resistance is not less than 1 Ohm, check all wiring harness connections and ground screws

8. 8

   If resistance is less than 1 Ohm, disconnect BL2 and WH4 connectors from main PCB

9. 9

   Measure resistance between BL2-1 (WH) and WH4-1 (YL): must be less than 1 Ohm with door closed and infinity (open) with door open

10. 10

    If readings are incorrect, replace door switch

11. 11

    If readings are correct, replace main PCB

12. 12

    For drum light check: measure resistance between WH4-2 (YL) and WH4-4 (BK) — less than 1 Ohm with door open, infinity with door closed; if not, replace light bulb or light socket
