A washing machine that won't start at all can range from a trivially simple fix (child lock, tripped outlet) to a significant repair (failed control board). The key is working through the causes in order of likelihood before spending money. This guide covers six causes for both front-load and top-load washers, with brand-specific notes for Samsung, LG, and Whirlpool.
5 Quick Checks Before Diagnosing Any Part
Do These First — All Are Free
Cause 1: Faulty Lid Switch (Top-Loaders)
1 Bad Lid Switch Maybe DIY
The lid switch is a safety device that prevents the washer from running when the lid is open. It's located under the lid, in the machine body. When you close the lid, a plastic actuator tab presses into the switch. If the tab breaks off, or the switch mechanism fails electrically, the machine never receives the "lid closed" signal and refuses to start.
Symptoms: Washer doesn't respond to Start at all with the lid closed, but otherwise shows power normally. You may hear no click when the lid closes.
Test: Open the lid and locate the small plastic switch mounted in the machine body near the lid opening. Look for the actuator tab (the plastic piece on the underside of the lid that presses the switch). If it's broken, the switch is never activated. You can also test by manually pressing the switch plunger while pressing Start — if the washer starts, the switch or actuator is the problem.
Cause 2: Bad Door Latch / Door Lock (Front-Loaders)
2 Door Latch / Door Lock Solenoid Call a Tech
Front-loading washers require two things before starting: the door must be physically latched (you feel/hear a click) AND electrically locked (a solenoid engages). If the door latch mechanism is worn or the door lock solenoid fails, the machine gets no "door secure" signal and won't begin a cycle.
Symptoms: Display shows a door error (dE, dL, F-Door depending on brand), or pressing Start causes nothing to happen with no error shown.
LG tip: LG front-loaders frequently show a dE1 or dE2 error for door latch issues. Try closing the door with firmer pressure — the latch hook must seat fully. If the error persists, the latch assembly needs replacement. Samsung tip: Samsung shows a dC or dE error. Check that the door seal gasket isn't bunched up preventing the door from closing fully.
Repair: Door latch/lock assemblies cost $30–$80 for parts. Total repair $100–$180 all-in with labour.
Cause 3: Control Board Failure
3 Failed Control Board Call a Tech
The control board (main PCB) is the brain of the washer. It receives input from the door switch/lid switch and all other sensors, then controls motors, valves, and pumps. When it fails, the washer may show power (lights on) but not respond to any button, show random error codes, or complete some cycles but not others.
Before assuming control board: Try a factory reset. Unplug the washer for 3–5 minutes, then plug back in and try again. This clears temporary faults that can mimic control board failure. On Samsung, press and hold Start for 5 seconds after power-on for a soft reset.
The fix: Control board replacement is $180–$320 all-in for most brands. It's worth doing on newer machines (under 8 years) but consider replacement if your washer is over 10 years old, as other components may be approaching end of life.
Cause 4: Power Supply Issues
4 Power Supply Problem DIY Fix
Washers require a dedicated 15–20A circuit. If the circuit is shared with another high-draw appliance (a dryer on the same circuit is a common mistake), the breaker may trip repeatedly. Additionally, GFCI-protected outlets in laundry rooms can trip and cut power to the washer without showing obvious signs.
Check for a tripped GFCI: Some laundry rooms have a GFCI outlet — look for a reset button on the outlet face. Press Reset firmly. Also check the main panel for a tripped breaker in the laundry circuit position.
Surge damage: After a lightning strike or power surge, the washer's internal fuse or control board may blow. Unplug for 5 minutes and retry. If still no response, a technician needs to check internal fuses before condemning the control board.
Cause 5: Child Lock Engaged
5 Child Lock Active DIY Fix
Child lock is the cause of more "my washer stopped working" calls than any other single non-mechanical issue. When active, all control panel buttons are disabled. The machine has power and looks functional but pressing any button including Start does absolutely nothing.
How to deactivate by brand:
- Samsung: Hold the Child Lock button (may be labeled with a padlock icon) for 3 seconds
- LG: Hold the Child Lock button for 3 seconds; some models require holding two buttons simultaneously
- Whirlpool/Maytag: Press and hold the Control Lock button for 3 seconds
- GE: Hold the Lock button for 3 seconds
- Bosch: Hold the Start button for 3 seconds while in standby mode
If you're unsure, unplug the washer for 60 seconds — some models reset child lock on power cycle.
Cause 6: Motor Overheating (Thermal Overload)
6 Motor Overheating DIY First
Washing machine motors have a thermal overload protector that trips and cuts power to the motor when it overheats — typically after running a heavy load, an off-balance cycle with excessive agitation, or an unusually long cycle. After tripping, the motor needs 20–30 minutes to cool before the protector resets automatically.
Symptoms: Washer stopped mid-cycle and now won't restart. Machine has power and display works, but pressing Start causes a brief hum then nothing, or nothing at all.
Fix: Unplug the washer, wait 30 minutes, then try again. If the washer starts normally, the thermal overload reset successfully. If it trips again repeatedly under normal loads, the motor or a bearing is working harder than it should — a technician should inspect it.
Front-Load vs Top-Load: Key Differences
Top-load: Relies on the lid switch as the primary safety interlock. No start without lid closed signal. Simpler door mechanism — no lock solenoid. Top-loaders can also have a water level pressure switch that prevents starting if it reads incorrectly (usually causes filling but not agitation rather than total failure).
Front-load: Uses a two-stage door lock (mechanical latch + electrical lock solenoid). Must sense door closed AND locked before starting. Front-loaders also require water in the drum to be fully drained from a previous cycle before starting a new one — if you interrupted a cycle with water still inside, it may show a door lock error until the drum is drained.

Frequently Asked Questions
A washing machine that won't turn on is usually caused by a power supply issue (tripped outlet or GFCI), a faulty door latch or lid switch, child lock engaged, or a failed control board. Check the power outlet first — plug in another device to confirm power is reaching the outlet. If power is confirmed, check whether the door is fully closed and the lock mechanism clicks into place.
On a top-loading washer, the lid switch is a safety device under the lid that must be activated (pressed down) when the lid closes. If the plastic actuator tab on the lid is broken, or the switch itself has failed, the machine thinks the lid is always open and refuses to run. Test by pressing the switch plunger manually — you should hear a click. Lid switch replacement costs $80–$160 all-in.
Child lock (also called control lock) disables all buttons on the washer to prevent accidental cycle changes. When activated, pressing Start does nothing. On most Samsung washers, hold the Child Lock button for 3 seconds. On LG, hold the Child Lock button. On Whirlpool, press and hold two specific buttons simultaneously (varies by model — check your manual). The control panel usually shows a lock icon when child lock is on.
If the display is on and shows settings but pressing Start does nothing, the most common causes are: child lock engaged, door latch not fully seated, an unbalanced or overloaded drum, or a delayed start timer set accidentally. Confirm the door clicks shut, check for a lock indicator on the display, and try pressing and holding the Start button for 3 seconds on Samsung/LG models.
Yes. Modern front-loading and HE top-loading washers have sensors that detect drum weight and balance. An overloaded drum may trigger a protection mode where the machine refuses to start until items are removed. Additionally, if a previous cycle ended with an off-balance load and the drum is still unbalanced, the machine may not begin a new cycle. Remove some items and redistribute the load before restarting.
Yes. Front-loaders use a door latch with a door lock solenoid — the door must be physically latched AND electrically locked before the cycle starts. If the lock mechanism is faulty, the machine shows a door error and won't start. Top-loaders use a simpler lid switch. Top-loaders also sometimes have a water level pressure switch that prevents starting if it reads incorrectly.
Repair costs depend on the cause. Lid switch or door latch replacement: $80–$180. Control board: $180–$320. Motor overheating/thermal overload reset: $0 (wait 30 minutes) to $150 for motor replacement if damaged. Nick's Appliance Repair charges an $89 diagnostic fee waived when you proceed with the repair.
