Understanding the Problem
If your Whirlpool WTW5057LW0 is making loud grinding, rattling, or banging noises specifically during the agitation portion of the wash cycle (when the agitator moves back and forth), that indicates wear or failure in the parts that transfer motor torque into the agitator or in the agitator assembly itself. Agitation noise is usually different than spin noise — it’s lower speed and often sounds like grinding, knocking, or a repeated clicking as the agitator tries to reverse direction. Common faulty areas include the agitator’s internal components (directional cogs/dogs, cam, bolt/cap), the drive coupling between motor and transmission, or the transmission/gearcase itself. Less commonly, a foreign object lodged between the tub and outer tub or a loose basket/tub can cause noise. Proper diagnosis requires a few safe checks (listening with the cabinet off, feeling for play in the agitator, and inspecting removed parts for wear or metal debris).
Common Symptoms
Loud grinding, clicking, or knocking during the agitation portion of the cycle; agitation speed hesitation or shuddering; sometimes visible wobble or excessive play in the agitator; occasional burning smell if coupling or motor is slipping.
Common Causes
- Worn or broken agitator directional dogs/cogs or damaged agitator cam/bolt allowing slipping and loud repetitive clicking
- Failing drive components (motor coupling or coupler) that slip or tear under load, causing grinding or clunking
- Damaged or worn transmission/gearcase (wearing gears or bearings) producing grinding or heavy metallic noise during agitation

Helpful Repair Tip
Safely unplug the washer, remove the agitator cap and upper agitator, and inspect the plastic directional dogs/cogs and the agitator drive coupling for broken teeth or heavy wear — these are quick visual checks that often identify the noisy part.
Frequently Asked Questions
Can I safely diagnose and replace the noisy part myself?
Yes — basic diagnosis (listening, checking for play in the agitator, removing the upper agitator to inspect dogs/cogs and the bolt) is something a handy homeowner can do with basic tools. Always unplug the washer first and keep track of fasteners. Replacing agitator dogs, the cam, or the upper agitator is typically straightforward. Replacing the motor coupling or the transmission/gearcase is more involved and may require lifting the washer, removing panels and the drive motor; if you’re not comfortable with that, call a technician.
How much does it cost to repair a loud agitator noise?
Parts-only: agitator repair kits or directional dogs are usually inexpensive ($15–$60). Motor couplings are generally $10–$40. A replacement transmission/gearcase is substantially more ($150–$450+ depending on OEM vs aftermarket). Labor (if you hire a tech) typically adds $150–$300 depending on location and the complexity of the repair. Exact cost depends on which part is failing and local labor rates.
