Direct answer: When a washer is not agitating, the most common causes are the wrong cycle selection, a load that is packed too tight, a lid or door lock that is not proving closed, or a worn washer drive belt on belt-driven models. If it fills and drains normally but the basket or agitator never does the wash stroke, narrow down whether the machine is skipping agitation entirely or just acting like it has no strength.
Most likely: Start with settings, load condition, and lid or door lock behavior. Those are more common than a major internal failure and they are easy to confirm without taking the washer apart.
Watch one full fill-to-wash transition. That moment tells you a lot. If the washer fills, clicks, and just sits there, think lid or door lock first. If you hear the motor trying but the tub does not do a wash stroke, think drive belt or a worn drive connection. Reality check: some modern cycles agitate in short bursts with long pauses, so a normal machine can look dead if you only watch it for a few seconds. Common wrong move: forcing the timer ahead or restarting the cycle over and over before you confirm the washer is actually supposed to be agitating at that point.
Don’t start with: Do not start by ordering a motor, transmission, or control board. On a lot of washers, the problem is a simple cycle choice, an overloaded tub, or a lid lock that never fully engages.
The tub fills to the normal level, then you hear a click or a short hum, but there is no back-and-forth wash motion.
Start here: Check the selected cycle first, then watch whether the lid or door lock actually engages.
You hear the washer trying to run, but the agitator or wash basket does not move normally or only twitches.
Start here: Unload part of the load and look for a slipping washer drive belt or worn drive connection.
A light load washes, but towels, jeans, or bedding make the washer stall or stop washing.
Start here: Rule out overloading and load tangling before assuming an internal part has failed.
The machine may drain and spin at the end, but the clothes come out barely washed because agitation never happened.
Start here: That pattern points away from a total power problem and toward settings, lid lock, or the wash-drive side of the machine.
Many washers use very short wash strokes on certain cycles, and some options hold the tub full of water for a while before real agitation starts.
Quick check: Run a normal wash cycle with a small towel load and wait through the full fill-to-wash transition for at least a minute.
An overloaded or badly tangled load can keep the washer from starting a proper wash stroke, especially with bulky items or mixed heavy fabrics.
Quick check: Stop the cycle, spread the load loosely, remove a few items, and test again.
If the control does not see a safe closed-lid signal, many washers will fill but refuse to agitate or will just click and wait.
Quick check: Close the lid or door firmly and listen for a solid lock sound. If it never locks, locks late, or unlocks itself, stay on this path.
A stretched or glazed belt can let the motor run without giving the washer enough grip to start agitation, especially under a normal load.
Quick check: If you hear the motor running during the wash portion but there is little or no movement, inspect the belt if your model uses one.
A lot of no-agitation calls turn out to be a cycle choice, a long programmed pause, or a machine that is still sensing the load.
Next move: If the washer begins a normal wash stroke on the test cycle, the machine was likely on a low-action cycle or reacting to the original load. If it fills and then just sits, clicks, or hums without any wash motion, move to the lid or door lock check next.
What to conclude: You want to separate a normal programmed pause from a real failure before opening the machine or buying parts.
Washers lose a lot of wash action when bedding, rugs, or heavy mixed items ball up and pin the basket or agitator.
Next move: If agitation comes back with a lighter, looser load, the washer was being overworked rather than suffering a hard part failure. If a small balanced load still will not agitate, keep going. The problem is likely in the lid lock or drive system.
What to conclude: This step separates a setup problem from a real machine problem. Differentiate load trouble from internal failure early so you do not chase parts you do not need.
On many washers, agitation will not start until the control sees a proper closed and locked signal. A weak or failing lock often shows up as fill-then-wait behavior.
Next move: If the washer starts agitating after you clean the strike area or close the lid or door more firmly, the lock was not making a reliable connection. If the washer still fills but never starts washing and the lock behavior is weak, delayed, or erratic, a washer lid lock assembly or washer door lock assembly is a strong suspect.
If the lock is working and the washer still will not agitate, the next common homeowner-level failure is a worn belt on belt-driven machines.
Next move: If a new belt restores normal wash motion, the old belt was slipping under load and not transferring enough force for agitation. If there is no belt on your design, or the belt looks sound and the washer still will not agitate, the problem is deeper in the drive system and usually not a guess-and-buy repair.
By this point you should know whether the problem was settings, load condition, lock behavior, or a clearly worn belt. If not, the remaining failures are usually model-specific drive parts or controls that need a tighter diagnosis.
A good result: If the washer completes a normal wash cycle and the clothes come out properly cleaned, you have likely solved the problem.
If not: If it still fills and skips agitation with no clear belt or lock failure, the next repair usually involves model-specific internal drive parts or electrical testing.
What to conclude: This is where you either make a supported repair or stop before the cost of guessing outruns the value of the fix.

The most common reasons are the wrong cycle, an overloaded or tangled load, or a lid or door lock that is not proving closed. If you hear the motor trying to run, a worn washer drive belt is also possible on belt-driven models.
Yes. Some washers can still drain or spin even when the wash portion never happens. That usually points away from a total power failure and more toward settings, the lock circuit, or the wash-drive side of the machine.
Watch for fill-then-wait behavior, repeated clicking, a lid that has to be pushed down or sideways to start, or a lock that never gives a solid engaged sound. If cleaning the strike area does not help, the washer lid lock assembly is a common fix.
Usually yes, if your washer uses a belt and the belt is clearly loose, cracked, glazed, or slipping. A belt is a reasonable DIY repair compared with guessing at deeper internal drive parts.
Not first. Motors are not the first thing to buy for this symptom. Confirm the cycle, load condition, lock behavior, and belt condition before you consider a deeper drive-system diagnosis.
Treat that as a different problem pattern. Hard banging points toward balance or suspension trouble, and a burning smell can mean a slipping belt, overheated motor, or wiring issue. Stop testing and address that symptom before running more cycles.
