| Motor hums but tub won't turn |
⚠️ Possible |
Failed capacitor, broken belt, seized bearings, jammed pump, motor coupler |
Test the capacitor first (most common); inspect belt; then motor |
| Tub won't turn and no hum |
⚠️ Possible |
Control board not sending power, timer fault, wiring fault, thermal fuse |
Test voltage at motor terminals during a cycle — no voltage = motor is fine |
| Tub spins freely by hand but nothing happens when powered |
✅ Possible |
Motor windings open, motor coupler broken (direct-drive), board output stage |
Test motor winding continuity |
| Tub won't spin freely by hand |
❌ Not the motor |
Tub bearings seized, foreign object in tub, jammed pump |
Look for foreign objects; then test the bearings |
| Motor runs but tub doesn't move (belt is intact) |
❌ Not the motor |
Motor coupler broken (direct-drive), stripped belt pulley, worn clutch |
Inspect the coupler and pulley |
| Motor turns weakly / spin is slow |
⚠️ Possible |
Worn capacitor, worn brushes (universal motors), degraded windings |
Test the capacitor; then test the motor |
| Burning smell during spin |
⚠️ Possible |
Belt slipping, wiring fault, burned motor, failed capacitor |
Unplug immediately. Check the belt first, then the motor |
| Washer trips the breaker at spin start |
⚠️ Possible |
Motor short, wiring fault, capacitor short, control board |
Stop using. Electrical hazard. Professional diagnosis required. |
| Grinding or roaring noise during spin |
❌ Usually not the motor |
Worn tub bearings, foreign object in tub, loose counterweight |
Inspect tub and bearings — motor noise is rare |
| Motor overheats and stops after 10–20 min |
⚠️ Possible |
Overload, degraded windings, failed capacitor, control board |
Reduce load; test capacitor; then motor |
| Error code pointing at motor (LG LE, Samsung 8E, Bosch E21, Whirlpool F7E1) |
⚠️ Possible |
Motor, capacitor, wiring, or control board |
Test capacitor first; then motor; then board |
| Washer works intermittently — sometimes spins, sometimes not |
⚠️ Possible |
Wiring fault, intermittent control board, degraded motor brushes |
Test motor brushes (universal motors) |
| Washer stops mid-cycle with no specific code |
❌ Usually not the motor |
Drain fault, pressure switch, control board |
Check the filter, drain hose, then the board |
| Washer is completely dead — no lights, no display |
❌ Not the motor |
Outlet, breaker, thermal fuse, control board |
See the Not Turning On page |
| Unbalanced load error code (LG UE, Samsung UE/Ub) |
❌ Not the motor |
Unbalanced load, worn suspension, faulty balance sensor |
Redistribute load; check suspension |
| Motor runs but tub slips (grinding + spinning) |
❌ Not the motor |
Worn belt, worn pulley, failing clutch |
Inspect the belt and pulley |
