Samsung Washer Code dC1 / dE1: Door Lock After Closing

Medium · inspection needed

Code: dC1 / dE1
Appliance: Washer
Brand: Samsung
Warranty: 30-day workmanship

What dC1 / dE1 means

On Samsung WF45-series front-load washers, dC1 or dE1 sits in the door error group, and the model table describes dC1 as the door not being locked after the close-door operation. The WF45M5500A is one example that shows DC1. The cycle stops because the control cannot confirm the lock. The spelling dE1 appears in the owner-facing group of door errors, not in the table of the control itself.

Common causes of dC1 / dE1

Door lock switch terminal wiring
Door latch movement and alignment
Intermittent wiring contact
Main control board input for the lock

✓ One safe check you can try

1. Open the door and check for clutter, a sock, or anything caught at the latch. 2. Close the door firmly until you hear it latch. 3. Restart the cycle. 4. If dC1 or dE1 returns, book a visit and avoid forcing the door.

! Why to stop there

The code says the lock was not confirmed but not whether the latch, the switch, or the wiring is responsible.
We test the lock switch reading and look for an intermittent wire contact.
If the control input is the cause, you get the written price first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

dC1 / dE1dC1 / dE1 questions

What is the difference between dC and dC1?

The table lists dC for a door not opened after the open operation and dC1 for a door not locked after the close operation. dC1 is about the lock after you shut the door.

Does dE1 point to something other than dC1?

The owner-facing group lists dE1 among the door errors, while the control's own table uses dC1. We treat them as the same door lock concern.

Can a loose wire cause it?

Yes, an intermittent connection at the lock switch can drop out and trigger the code. That is one of the first things we check. We look at the wire ends and the switch terminals for signs of looseness.
