Replacing a 6601ER1004D? This is the part
If the lock you removed is marked 6601ER1004D, that number is no longer produced. LG replaced it with EBF49827803, which is this component. You do not need to keep searching for the old number, it has been superseded, and the replacement fits the same machines with the same mounting and the same wiring.
This is the single most common reason owners of older LG machines are told their part is unavailable. It is available. It just has a different number on it.

Commercial laundry
This part number is also listed for Primus commercial washing machines. If you run a laundromat, a hotel laundry or a labour-accommodation facility, this is the interlock your machines take — and we hold it in stock locally rather than ordering it in from overseas. Contact us for quantity pricing.
What this part does
The interlock tells the control board the door is shut and holds it shut while the drum turns. Nothing starts until its contacts close — no fill, no wash, no spin.
It works by a PTC thermal element rather than a solenoid. Power reaches the element, it heats and expands, and the latch drives home. At the end of the cycle the power is cut and the element must cool before the latch releases, which is why an LG front loader keeps the door shut for a short period after the programme ends. That delay is designed behaviour, not a fault.
Is the interlock actually the fault?
Points to the lock
- Door shuts and latches mechanically, but the machine will not start the programme
- No audible click from the lock when the cycle is started
- Machine fills but will not spin, with the door firmly shut
- Door stays locked indefinitely after the cycle, long after the drum has stopped
- Continuity test across the switched terminals shows an open circuit after the lock has been energised
Points to something else
- Door will not latch mechanically: Hinge, striker plate or door seal
- Machine dead, no display: Supply or main board
- Cycle completes and the door opens normally: The interlock is working
- Fault returns immediately with a new lock fitted: The wiring harness or the control board
Before you test or remove it: disconnect the machine from the mains. The interlock terminals carry 250 V during operation.
How to confirm this is your part
- Read the old lock. Look for DFF01 on the black face, with the ROLD article 46987.035 beside it.
- Check for 6601ER1004D. If that is the number on your old part, this is its replacement.
- Count the terminals. Three, numbered 3, 4 and 5. A different count is a different part.
- Check the mounting bracket. Two-hole black bracket with the actuator aperture on the upper face.
- Send us a photo of the old part on both faces. We confirm the fitment before you pay.

Frequently asked questions
Q1. My old lock says 6601ER1004D. Is this the right replacement?
Yes. LG superseded 6601ER1004D with EBF49827803, which is this part. Mounting, wiring and function are unchanged.
Q2. What is the difference between DFF01 and DFS03857?
They are two ROLD versions of the same LG part number. Both are supplied against EBF49827803. Compare your old lock against both before choosing, or send us a photo and we will tell you which one matches your mounting and connector.
Q3. My machine is old and has no error display. How do I know the lock has failed?
The signs are a door that latches mechanically but produces no click and no programme start, a machine that fills but will not spin with the door shut, or a door that will not release after the cycle ends. If the door will not latch at all, look at the hinge, the striker and the gasket instead.
Q4. Does it really last 30,000 cycles?
That is the endurance class marked on the body as 3E4. It is a manufacturer rating under test conditions, not a warranty. Real service life depends on load, moisture and how the machine is used.
Q5. Can I use this in a commercial washing machine?
LG part EBF49827803 is catalogued for Primus commercial machines as well as domestic LG front loaders. Check your machine’s part number against ours before ordering, and contact us for quantity pricing.
