Error Code dE

Door switch abnormal

Also displayed as: dE

How to Fix

1. 1

   Enter diagnostic mode and press START/PAUSE once; dryer tumbles without heat.

2. 2

   Open door; dE should display and chime should sound 7 times if sound is on; drum light (if equipped) should come on.

3. 3

   If dE displays and light comes on, door switch is working properly — problem is elsewhere.

4. 4

   If dE does not display, disconnect WH1 and BL3 connector from main PCB.

5. 5

   Measure resistance between WH6 pin (GN) and chassis ground screw; should be less than 1Ω.

6. 6

   If greater than 1Ω, check all wiring harness connections and ground screws.

7. 7

   If less than 1Ω, disconnect BL2 and WH4 connectors from main PCB.

8. 8

   Measure resistance between BL2 (WH) and WH4 (YL); should be less than 1Ω with door closed and open circuit (∞) with door open.

9. 9

   If incorrect, replace door switch.

10. 10

    Also check WH4 (YL) and WH4 (BK); if resistance is not less than 1Ω with door open and ∞ with door closed, replace light bulb or socket.

11. 11

    If all mechanical checks pass but error persists, replace the main PCB.
