Why Won't My Samsung Washing Machine Start?
Check that the door is firmly closed until it clicks — a door that isn't fully latched is the most common reason a Samsung washing machine refuses to start, and pressing it shut properly will usually allow the cycle to begin immediately (takes about 1 minute).
Fault description
When you press Start on your Samsung washing machine and nothing happens, it can be frustrating — especially when there's no obvious sign of what's wrong. The machine may sit completely silent, display a blinking light, or show an error code such as dE (door error). In some cases the display lights up normally but the drum simply never begins to turn.
Most of the time, a Samsung washing machine that won't start is being prevented from doing so by a built-in safety system. These systems are designed to protect both the machine and your home, so the appliance is doing exactly what it's supposed to — it just needs a small issue resolved before it will run. The fault is rarely serious, and the majority of cases can be sorted without any tools or specialist knowledge.
The areas most commonly involved are the door latch, the power supply, the control settings, and the water supply. Working through these in order is the quickest way to get your machine running again.
Causes
- Door not fully closed or door latch faulty — Samsung machines will not start a cycle unless the door is securely latched. If the door seal, a stray item of clothing, or a worn latch is preventing a proper close, the machine interprets this as an open door and refuses to run — often displaying a dE error code.
- Child lock or control lock is active — Samsung washing machines have a child lock feature that disables all buttons to prevent accidental operation. If this has been switched on — sometimes accidentally — pressing Start will have no effect and a small lock icon may appear on the display.
- Power supply issue — A tripped circuit breaker, a loose plug, or a faulty wall socket can all prevent the machine from receiving power. The machine may appear completely dead or may lose power mid-cycle.
- Water supply not connected or tap turned off — Samsung machines check for a water supply before starting. If the inlet tap is closed, the hose is kinked, or the water pressure is too low, the machine may refuse to begin filling and therefore won't start the cycle.
- Delay Start or demo mode is active — If Delay Start has been set, the machine will wait until the programmed time before running. Similarly, if the machine has been placed into demo or retail mode, it will appear to function but will not actually start a wash.
- Control board or start button fault — In less common cases, the main control board or the start button itself may have failed. This is more likely on older machines or after a power surge, and usually requires a service technician to diagnose properly.
Step-by-Step Fix
- 1
Check the door is properly closed
Open the door fully and close it again firmly until you hear a clear click. Inspect the door seal for any clothing or debris caught in the rim that might be preventing a full close. If the machine shows a dE error code, this is almost certainly the cause.
- 2
Disable child lock if it is active
Look for a padlock icon on the display. On most Samsung models, child lock is deactivated by pressing and holding two specific buttons simultaneously for three seconds — check your model's user manual for the exact combination, as it varies. Once deactivated, try starting the cycle again.
- 3
Check the power supply
Make sure the plug is fully inserted into the socket and that the socket is switched on. Try plugging a different appliance into the same socket to confirm it is working. Check your home's fuse box for any tripped breakers and reset if necessary.
- 4
Check the water supply
Locate the hot and cold inlet taps behind the machine and confirm both are fully open. Inspect the inlet hoses for kinks or tight bends that could restrict flow. If you have low water pressure in your home generally, this may also be a contributing factor.
- 5
Cancel any Delay Start setting
Press the Delay Start button repeatedly to cycle through and cancel any programmed delay, or press and hold the Start/Pause button for several seconds to reset the current programme. Check the display to confirm no delay timer is showing before pressing Start again.
- 6
Perform a reset on the machine
Turn the machine off at the wall socket, wait 60 seconds, then switch it back on. This clears any temporary software glitches that may be preventing the machine from responding. Select your programme fresh and press Start — do not carry over any previous settings.
- 7
Inspect the door latch mechanism for visible damage
With the machine unplugged, examine the plastic door latch hook and the strike plate on the machine body. If either part is cracked, bent, or visibly worn, the latch will not engage correctly even when the door appears closed. A replacement door latch is a straightforward part to fit and is available for most Samsung models.
When to call a service technician
If you have worked through all the steps above and the machine still will not start, it is time to contact a service technician. Specific signs that point to a more serious fault include: the machine is completely dead with no display even though the socket is confirmed working; the Start button feels unresponsive or physically damaged; or the machine trips your home's circuit breaker when plugged in.
A persistent dE error code that remains even after confirming the door closes properly can indicate a failed door latch assembly or a wiring fault between the latch and the control board — both of which are best diagnosed with the right test equipment. A service technician can also identify control board faults safely, which should not be attempted without experience.
Prevention
The parts most commonly replaced when a Samsung washing machine won't start are the door latch assembly (also called the door lock or interlock), the door handle (which can break and prevent the door closing properly), and the main control board PCB in cases where the electronics have failed. Of these, the door latch is by far the most frequent replacement and is straightforward for a confident homeowner to fit using basic tools.
To avoid repeat issues, make a habit of not overloading the drum — excess laundry can press against the door seal and prevent a clean close. Check the door seal periodically for small items such as coins or clips that can lodge in the rim and interfere with the latch over time.

Frequently Asked Questions
What does the dE error code mean on a Samsung washing machine?
The dE code stands for Door Error and means the machine cannot confirm the door is properly closed and locked. This is one of the most common reasons a Samsung washing machine won't start. Check for obstructions around the door seal and press the door firmly shut. If the code persists with the door properly closed, the door latch may need replacing.
My Samsung washing machine has power but won't start — what should I check first?
If the display is on but the machine won't begin a cycle, the most likely culprits are an active child lock, a Delay Start setting, or a door that isn't fully latched. Check for a padlock icon on the display and look for any timer countdown. These are all quick to resolve without any tools.
Can a Samsung washing machine refuse to start because of low water pressure?
Yes. Samsung machines carry out a basic check before filling and may not proceed if water pressure is too low or if no water is detected. Make sure both inlet taps are fully open and the hoses are not kinked. If your home has generally low water pressure, this can occasionally cause intermittent starting problems.
How do I turn off child lock on a Samsung washing machine?
The method varies slightly by model, but on most Samsung machines you press and hold two buttons simultaneously for around three seconds — common combinations include Temp + Spin or Rinse + Spin. Refer to your model's user manual for the exact buttons. A padlock icon disappearing from the display confirms it has been deactivated.
Is it safe to keep using my Samsung washing machine if it sometimes won't start?
Intermittent starting problems are worth investigating promptly rather than ignoring. If the issue is a worn door latch, continued use can put strain on the door wiring and eventually cause a more expensive fault. If the machine is tripping your electrics when it tries to start, stop using it immediately and call a service technician.
