Most likely causes

  1. Laundry caught between the door and the rubber gasket, or a lid not fully shut
  2. Debris or an obstruction around the latch or strike
  3. Worn or cracked door lock switch (latch) assembly
  4. Latch not physically engaging, or the switch not confirming lock
  5. Loose wiring to the door lock or a control board fault
Before you start — unplug the appliance and turn off the water supply. You'll be working near water and electrical parts, and drained water can be hot. If a step involves the pump, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

3Clear the latch areaInspect the latch and strike for lint or debris and clean out anything blocking the lock.

Still showing dE?

If you’ve worked through every step and dE keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
