Defy Washing Machine Door Interlock - Get Your Machine Locking and Running Again
Is your Defy washing machine refusing to start because the door will not lock, or are you getting a door or lock fault every time you try to run a cycle? The door interlock is the safety switch that locks the door and tells the machine it is safe to run, so when it fails the machine simply will not start, or will not release the door at the end of the wash.
This genuine Defy door interlock (Part No. 2847740400) is a direct-fit replacement that restores safe, reliable door locking, getting your machine back to normal operation. It is the correct repair for a lock fault, and it saves the cost of replacing a machine that is otherwise in good order.

Why Choose a Genuine Part:
Genuine Defy parts match the original connectors and mounting points of your appliance, which means the interlock bolts up correctly, plugs in cleanly, and locks and releases in step with the machine's controls. Generic copies often misfit, connect incorrectly, or fail again quickly, leaving you back where you started with a machine that will not start. Fitting the genuine part restores your washer to the way it was engineered to work and gives you safe, dependable door locking for the long term. For a safety-related part like this, correct fit and specification are what make the repair worthwhile.
Installation and Care:
- Always unplug the machine and turn off the water supply before starting the repair.
- Note the connector position and mounting screws before removing the old interlock, so the new one goes back the same way.
- Fit the new interlock using the existing mounting points and reconnect the wiring connector securely.
- Make sure the door catches and the lock engages properly before running the machine.
- Run a cycle to confirm the door locks at the start, stays locked during the wash, and releases at the end.
A faulty door interlock stops your machine before it can even start, and the genuine 2847740400 part is the safe, reliable way to restore proper door locking and normal operation to your Defy washing machine.
