Michael Thompson Key Takeaways
- Direct drive removed the belt and transmission, so the usual suspects on an older washer simply are not there.
- A machine that fills and drains but never turns the drum is often the rotor position sensor rather than the motor.
- The drum bearing is an inexpensive part with expensive labour, because reaching it means separating the outer tub.
- Turn the drum by hand: smooth with slight resistance is healthy, and grinding or knocking points at the bearing or the spider.
- A machine abandoning a spin it cannot balance is behaving correctly — redistribute the load before calling it a fault.
The Bottom Line
Ask specifically whether the motor tested bad or the position sensing did — they cost very different amounts and look identical from the laundry room. A bearing on a machine past ten years is where most people replace, and reasonably.
A washer that fills and drains but will not turn the drum is the complaint that most often ends in a new machine, and quite often it should not. An LG direct drive motor is bolted to the back of the drum with no belt and no transmission between them, which removes the two parts that used to fail most — and concentrates attention on a small number of things that are, individually, not expensive. Deciding well starts with knowing which of them you have.
| What it does | Likely cause | Lean toward |
|---|---|---|
| Fills and drains, drum never turns | Rotor position sensor, or the motor | Diagnose — different prices |
| Turns freely by hand with a grinding feel | Bearing | The genuinely expensive one |
| Attempts to spin, stops, retries | Unbalanced load, or the sensor | Redistribute first, then diagnose |
| Loud metallic noise on spin only | Bearing, or something in the outer tub | Diagnose before running it again |
| Washes fine, will not reach high spin | Control, sensor, or suspension | Repair |
| Drum has dropped or rubs the cabinet | Spider or bearing housing | Usually replace |
What Direct Drive Removed, and What It Did Not
On a belt-driven washer the belt and the transmission were the usual suspects, and both were wear items. A direct drive machine has neither: the rotor is attached to the drum shaft and the stator is fixed to the tub behind it. Fewer moving parts, less to wear, and a quieter machine.
What did not go away is the bearing the drum turns on, and that is the part that decides most of these conversations. A bearing is not expensive as a part; replacing it means separating the outer tub, which on many designs is most of a day's work. That labour, not the component, is what makes a bearing job the line where repairing a washer stops being obvious.
The Sensor People Mistake for the Motor
The control needs to know exactly where the rotor is to drive it, and a small sensor on the motor tells it. When that sensor fails, the control cannot drive the motor safely and simply does not — producing a machine that fills, drains, and never turns the drum. From the laundry room that is indistinguishable from a dead motor.
It is a fraction of the price, and it is common enough to be worth asking about specifically. A technician confirming a direct drive fault should be able to say whether the motor tested bad or the position sensing did.
The Free Test
- Empty the machine and turn the drum by hand. It should turn smoothly with slight resistance and no grinding.
- Lift and push the drum gently at the front. Noticeable movement or a knocking feel points at the bearing or the spider.
- Listen on spin, if it will spin. A bearing noise rises and falls with speed; something loose in the tub is intermittent and irregular.
- Check for a small object. Coins and underwire migrate between the inner and outer tubs and produce alarming noises on a perfectly sound machine.
- Redistribute the load before treating a failure to reach high spin as a fault. Modern machines abandon a spin they cannot balance, correctly.
Our guide on an LG washer not spinning covers the rest of that list.
Noise Is the Most Useful Symptom Here
On a washer, noise carries more diagnostic information than almost anything else, and describing it well shortens an appointment considerably:
- A rumble that rises and falls with drum speed and is worst on spin points at the bearing.
- A rhythmic knock at low speed that disappears at high speed is usually a load that has not distributed.
- An irregular clatter that comes and goes is something loose between the tubs — coins, buttons, underwire.
- A hum with no movement is the motor being told to turn and not doing it, which is the sensor-or-motor question above.
- A grinding that you can also feel turning the drum by hand is the bearing, confirmed.
The Line
- Position sensor, control, or suspension: repair, at almost any age.
- Motor itself, machine under eight years: usually repair.
- Bearing, machine under six or seven years: worth a written estimate — the labour is significant and the machine has life left.
- Bearing, machine past ten years: this is where most people replace, and reasonably.
- Drum dropped, spider corroded: replace.
Unlike built-in kitchen appliances, a washer is genuinely replaceable — it slides out and another slides in — so no cabinetry argument keeps the ceiling artificially high. The exception is a stacked or closet-fitted set, where matching the footprint brings some of that premium back. Our washer decision guide takes that further.
Getting a Number
Diagnostic visits start from $89, with the final price confirmed after the on-site diagnosis and a written estimate before any work begins. Do the hand test before booking and describe what you felt — a drum that turns smoothly and a drum that grinds lead to entirely different appointments.
Our LG washer repair service covers the direct drive motor, the position sensing, the suspension, and the controls. Book a visit rather than running a machine that is making a new metallic noise — whatever is loose is getting worse each cycle.
