Why Won't My LG Washing Machine Start?
Press the door firmly shut until you hear a click, then press Start — a door that appears closed but hasn't latched properly is the most common reason an LG washing machine won't start (takes about 1 minute).
Fault description
When you press Start on your LG washing machine and nothing happens — no drum movement, no water filling, no sounds at all — it can feel alarming. In most cases, though, the cause is straightforward and something you can resolve yourself without any tools or specialist knowledge.
The fault usually lies with the door latch, the power supply, or a control setting that has been activated accidentally. LG machines are designed to refuse to start if the door is not fully secured, which is a safety feature rather than a malfunction. Related error codes such as dE, dE1, and dE2 all point specifically to a door that the machine does not recognise as properly closed.
Less commonly, a tripped circuit breaker, a Child Lock that has been switched on without the owner realising, or a fault with the control board can prevent the cycle from starting. Working through the checks below in order will help you identify the cause quickly.
Causes
- Door not fully latched — LG washing machines will not start unless the door is securely closed and the latch is engaged. If the door seal, a stray item of clothing, or a worn latch hook prevents a firm click, the machine stays locked out and may display dE, dE1, or dE2.
- Child Lock activated — The Child Lock feature disables all buttons on the control panel to prevent accidental operation. It is easy to switch on by accident, and when active the machine will appear completely unresponsive to the Start button.
- Power supply issue — A tripped circuit breaker, a loose plug, or a faulty wall socket can cut power to the machine entirely. The display may be blank or dim, and pressing any button will have no effect.
- Delay Start or Pause mode engaged — If Delay Start has been set, the machine will wait for the programmed time before beginning the cycle. Similarly, if the machine was paused mid-cycle and then the door was opened, it may need to be reset before it will start again.
- Faulty door latch assembly — Over time the plastic hooks and the microswitch inside the door latch can wear or break. Even if the door appears closed, the machine's control board receives no signal confirming it is safe to start, triggering dE error codes.
- Control board or wiring fault — In a small number of cases, a failed main control board or a loose wiring harness connection means the Start command is never processed. This is less common but more likely on older machines or those that have experienced a power surge.
Step-by-Step Fix
- 1
Check the power supply
Make sure the machine is plugged in firmly and that the wall socket is switched on. Go to your consumer unit (fuse box) and check that the circuit breaker for the washing machine has not tripped. Reset it if necessary, then try starting the machine again.

Close the door firmly
Open the door fully, check that no clothing is caught in the seal or hanging over the door rim, then push the door closed with a firm push until you hear or feel a definite click. If a dE, dE1, or dE2 code is showing, this is almost certainly the cause. Try pressing Start immediately after latching.
- 3
Deactivate Child Lock
Look for a padlock icon on the display or a key symbol. On most LG models, Child Lock is deactivated by pressing and holding the Child Lock button (sometimes labelled CL) for 3 seconds. Refer to your model's manual if you are unsure which button to hold, as it varies between models.

Cancel Delay Start and reset the programme
Press the Power button to turn the machine off, wait 10 seconds, then turn it back on. Select your wash programme fresh and press Start without setting a delay. This clears any lingering Delay Start or Pause state that may be blocking the cycle.

Inspect the door seal and latch for damage
With the machine unplugged, examine the rubber door seal for tears or objects lodged in the folds. Then check the plastic latch hook on the door itself — if it is cracked, bent, or broken, it will not engage the strike plate correctly. A damaged latch hook is a straightforward part to replace yourself.
- 6
Perform a hard reset
Unplug the washing machine from the wall socket and leave it unplugged for at least 5 minutes. This allows the control board's capacitors to discharge fully and can clear software errors. Plug back in, select a programme, and try to start the machine.

Test the door latch microswitch
If the steps above have not resolved the issue and dE codes persist, the door latch assembly likely needs replacing. The latch contains a small microswitch that tells the control board the door is shut. Replacement latch assemblies are available as spare parts and can be fitted by a confident DIYer using a screwdriver, though if you are unsure it is safer to call a service technician.
When to call a service technician
If you have worked through all the steps above and the machine still will not start, or if the control panel display is blank even though the machine is receiving power, it is time to contact a service technician. These symptoms can indicate a failed main control board or a broken wiring harness — repairs that require specialist diagnostic tools and safe handling of electrical components.
You should also call a service technician if you notice any burning smell, scorch marks around the plug or socket, or signs of water damage near the control panel. Attempting to open the machine's electronics in these circumstances carries a genuine safety risk.
Prevention
The parts most commonly replaced when an LG washing machine won't start are the door latch assembly (including the microswitch), the door strike plate that the latch hooks onto, and — less frequently — the main control board. Keeping the door seal clean and free of debris reduces wear on the latch and helps it engage reliably every time.

Frequently Asked Questions
What does the dE error code mean on my LG washing machine?
dE, dE1, and dE2 all indicate that the machine's control board cannot confirm the door is properly closed. dE1 and dE2 are more specific variants that can point to a wiring issue with the door latch sensor. Start by pushing the door firmly shut; if the code persists, the latch assembly likely needs replacing.
My LG washing machine display is on but it won't start — what should I check first?
If the display is active but the machine won't respond to Start, Child Lock is the most likely culprit. Look for a padlock or key icon on the display and hold the Child Lock button for 3 seconds to deactivate it. If that doesn't help, check whether a Delay Start time has been set accidentally.
Can a power surge stop my LG washing machine from starting?
Yes. A power surge can trip the circuit breaker or, in more serious cases, damage the main control board. Check your fuse box first and reset any tripped breaker. If the machine still won't start after a reset and a 5-minute unplug, the control board may need professional assessment.
How do I know if my LG washing machine door latch needs replacing?
Signs of a failing latch include the door feeling loose even when pushed shut, a dE error code that won't clear, or a latch hook that is visibly cracked or bent. You can also listen for the click when closing the door — if there is no audible click, the latch is not engaging and will need to be replaced.
Is it safe to force the door shut to get the machine to start?
No. Forcing the door risks breaking the latch hook or damaging the door seal, turning a simple fix into a more expensive repair. If the door won't latch normally, investigate why — a small item of clothing caught in the seal is often the cause and takes only a moment to clear.
