A cracked or worn rear tub gasket fails to seal the drive shaft passage, allowing water to escape from the rear of the machine during wash and spin cycles.
Once the rear tub gasket fails, water and detergent enter the tub bearings (4280EN4001F / 4280EN4001G), causing bearing corrosion, loud noise, and eventual bearing failure.
A deteriorating gasket creates gaps where moisture accumulates, promoting mold and mildew buildup around the rear tub area and producing foul odors.
Over time, heat cycles and detergent exposure cause the plastic gasket to crack, warp, or lose its shape, breaking the watertight seal with the drive shaft.
💡 Pro Tip: Diagnosing a Failed Rear Tub Gasket
Your part is likely the culprit if you notice any of the following:
⚠️ Water leaking from the back or underneath the washing machine during wash or spin
⚠️ Visible cracks, tears, or deformation on the rubber/plastic gasket around the rear tub
⚠️ Mold or mildew buildup accumulating around the rear tub gasket area
⚠️ Loud grinding or rumbling noise during spin — a sign the gasket has failed and water has reached the tub bearings
⚠️ Important: Replacing this gasket requires full disassembly of the washing machine tub assembly. If you hear loud bearing noise in addition to leaking, inspect bearings 4280EN4001F and 4280EN4001G at the same time — these often fail together once the gasket seal is compromised.
