Understanding the Problem
Brief explanation: The W10528947 is a basket-driven drive hub (wash plate hub) used on many Whirlpool/Maytag/KitchenAid top-load washers. It connects the gearcase output to the washplate/agitator. When the plastic hub cracks or the splines strip, the motor and gearcase turn but the washplate and agitator do not — causing no agitation, poor spin, or error codes like F7E1 / F7E5 / F0E5. Diagnostic & repair steps: 1) Safety first: Unplug the washer or switch off the breaker and turn off the water supply. Work with the machine empty and stabilized. 2) Confirm symptom: Run a short agitation or spin cycle with the lid open (if safe) or with a test load. Listen for the motor/gearcase running but the basket/agitator not turning, or feel excessive play between the washplate and outer tub. Note any error codes (F7E1, F7E5, F0E5 commonly indicate basket/hub/gearcase drive issues). 3) Remove agitator/washplate: Typically remove the fabric softener dispenser/cap on top of the agitator, then remove the agitator retaining bolt (common sockets are 9/16" / 14 mm depending on model). Pull the agitator straight up — use a rubber mallet or agitator puller if it’s stuck. 4) Expose the hub: Remove the washplate or the top basket cover to access the drive hub. Inspect the hub for cracked plastic, stripped splines, or missing clips. If the hub is broken it will be obvious — large cracks, chunks missing, or the splines will be rounded/worn. 5) Remove old hub: The hub kit often has a snap ring or retaining clip and a center nut/bolt. Remove any clips and slide the bad hub off the shaft. If it’s fused or fractured internally, you may need to cut and remove pieces carefully with pliers or a dremel. Take pictures before removal to help reassembly. 6) Inspect gearcase: With the hub removed, check the gearcase output shaft for wear or scoring. If the gearcase output is damaged, you may need a gearcase replacement (e.g., W11454734 / W11454372). Also inspect the washplate and agitator splines. 7) Install new hub (W10528947): Clean the shaft and apply a light coat of appliance grease where recommended. Slide the new hub onto the output shaft aligning splines. Reinstall the retaining clip/snap ring and the center bolt/nut per the kit instructions. Some kits include a new bolt or cap — use the supplied hardware. 8) Reassemble agitator/washplate: Reinstall the washplate and the agitator, making sure the splines line up. Tighten the agitator bolt snugly (hand tools), but do not over-torque — refer to your model’s service data for torque specs if available. 9) Test: Restore power, run a diagnostic or a normal cycle and verify agitation and spin. Check for unusual noises, wobble, or slipping. 10) Final checks: Make sure there are no leaks and that the agitator/basket turns smoothly under load. Practical fix tips: If the hub is broken but the gearcase output looks smooth and undamaged, replacing the W10528947 hub kit will typically restore operation. If you find metal shavings, grinding noise, or a worn output shaft, plan to replace the gearcase as well. Safety note: Always disconnect power before working on the washer. Support the tub/inner basket if you need to remove suspension components. If the job requires cutting or forceful removal, wear eye protection and proceed cautiously to avoid damaging the outer tub or electrical components.

Helpful Repair Tip
Manually rotate the washplate/agitator with the motor off — if you see significant play between the washplate and basket or the washplate slides freely on the shaft while the gearcase runs, the hub is likely failed.
Frequently Asked Questions
Will W10528947 fit my washer model?
W10528947 fits many Whirlpool, Maytag and KitchenAid top-load washers that use a basket-driven hub design. Compatibility depends on the exact model and production date. Check your washer’s model number against the part listing on the manufacturer’s parts site or retailer — or enter your model into a parts lookup. If your old hub looks like the same shape/spline count and mounting style, it’s likely the correct part.
How difficult is the replacement and how long will it take?
Difficulty: moderate for a handy DIYer. Typical time: 45–90 minutes. Tools: socket set (common 9/16" or 14 mm for the agitator bolt), pliers, flat screwdriver, rubber mallet, penetrating oil (if stuck), and safety gear. If the hub is corroded or the gearcase output is damaged, expect extra time or consider a pro.
