Understanding the Problem
If your ATW4475 (top-load) washer fills, drains, or even hums but the drum doesn't spin or the agitator won't move, the machine is likely failing to transfer motor power to the tub. This problem can be caused by simple electrical failures (lid or lid switch), mechanical wear (broken or slipping drive belt), or drivetrain failures (motor coupling, clutch or transmission). Diagnosing the exact cause quickly narrows the repair to a single part in most cases. Start with basic safety: unplug the washer or switch off the breaker before inspecting. Many spin problems are straightforward to confirm and repair at home if you are comfortable removing the cabinet or access panel. If the motor runs (you hear humming or the motor attempts to turn) but the tub doesn't, the issue is typically mechanical; if the motor never gets power during the spin sequence, the problem is commonly a lid switch, door/sensor, or control/timer failure.
Common Symptoms
Drum does not rotate during spin; motor hums or tries to start; washer fills and drains normally; loud grinding or slipping noises; washer stops mid-cycle or displays no agitation.
Common Causes
- Faulty or broken lid/lid switch preventing spin motor power
- Worn, loose or broken drive belt (or belt has slipped off the pulley)
- Failed motor coupling, clutch, or transmission causing no power transfer from motor to tub

Helpful Repair Tip
Put the washer into a spin cycle and manually press the lid switch (or jump its connector with the power off) while listening: if the motor starts when the switch is engaged, replace the lid switch; if the motor hums but the tub doesn't turn, inspect the drive belt and motor coupling.
Frequently Asked Questions
Can I replace the lid switch or drive belt myself?
Yes — both are common DIY repairs on top-load machines if you have basic hand tools and follow safety precautions. Unplug the washer and follow a step-by-step guide: remove the top or control panel to access the lid switch, or tip the washer back/remove the cabinet to access the belt and motor area. Test the new part before reassembling fully. If you are uncomfortable removing panels or working near electrical components, hire a technician.
How much does it typically cost to repair a non-spinning ATW4475?
If the fix is a lid switch or belt, parts usually cost between $10–$60; a motor coupling kit may run $20–$50. Labor for a service call and repair typically adds $100–$250 depending on local rates. If the transmission or motor needs replacement, expect higher costs ($200–$600+). Always get a diagnosis first so you only replace the failed component.
