The WW01A00813 is a genuine OEM GE top load washer tub assembly designed for GE, General Electric, Westinghouse, Monogram, Café, Moffat, Profile, Sears, McClary, Hotpoint, and Kenmore (GE-made) top load washing machines. This critical component is the primary container that holds water and clothes during the wash cycle. The tub assembly is essential for proper washer function—without a functioning tub, the washer cannot hold water or clothes, causing complete washing failure. The WW01A00813 is a complete tub assembly that includes the inner tub, outer tub, transmission, motor, belt, and all assembly components necessary for installation. The washer top load tub assembly is constructed from premium materials including a stainless steel inner tub (provides durability, corrosion resistance, and long service life), stainless steel outer tub (provides structural support and water containment), transmission assembly (converts motor power to agitation and spinning), direct drive motor (provides power for agitation and spinning), serpentine belt (drives the transmission), sealed bearings (support the tub and provide smooth rotation), water inlet ports (allow water to enter the tub), drain port (allows water to exit the tub), and mounting bracket assembly (secures the tub to the washer cabinet). The WW01A00813 features a one-piece stainless steel construction that provides superior durability and corrosion resistance compared to older plastic or porcelain tubs. The inner tub is perforated with small holes that allow water to drain while retaining clothes. The outer tub surrounds the inner tub and contains the water. The transmission is mounted to the bottom of the tub assembly and converts the motor's rotational motion into agitation and spinning actions. The motor is mounted directly to the transmission, providing direct drive operation. The serpentine belt connects the motor to the transmission pulley. The tub assembly mounts to the washer cabinet using a mounting bracket assembly. The WW01A00813 replaces older tub assembly part numbers including WW01A00735, WW01A00816, AP5809535, PS5809535, 280000, and similar assemblies and features improved stainless steel construction for better durability and corrosion resistance (50% longer lifespan than previous generation), enhanced transmission design for better agitation and spinning performance, upgraded direct drive motor for higher efficiency and quieter operation, improved bearing design for smoother operation and reduced vibration, optimized water inlet and drain ports for better water flow, and reinforced mounting bracket for better stability across all compatible washer models. The washer top load tub assembly operates through integrated mechanical and hydraulic systems: when the washer wash cycle begins, the control board sends power to the motor; the motor rotates the transmission; the transmission converts the motor rotation into agitation motion; the agitator moves back and forth, agitating clothes; water fills the tub through the inlet ports; the agitator continues agitating clothes throughout the wash cycle; when the wash cycle ends, the control board changes the transmission to spin mode; the transmission converts the motor rotation into high-speed spinning motion; the inner tub spins at high speed, extracting water from clothes; water drains through the drain port; when the spin cycle ends, the control board turns off the motor; the tub stops spinning. Common failure causes include normal wear from age and repeated wash cycles (typical tub lifespan 15-20 years with average use), tub cracking or perforation from physical impact or thermal stress (most common failure), bearing failure from wear or lack of lubrication, transmission failure from wear or damage, motor failure from electrical stress or water damage, belt wear or breakage from age and use, water leakage from cracks or seal failure, manufacturing defects, or premature failure from low-quality replacement tubs. When the washer tub assembly fails, symptoms include water leaking from the tub (crack or seal failure, most common symptom), washer not agitating (transmission or motor failure), washer not spinning (transmission or motor failure), loud grinding or squealing noise from tub (bearing or transmission failure), visible cracks or damage to tub (physical damage), washer displaying error codes related to tub or motor (varies by model), or complete washing failure (tub unable to function). The WW01A00813 is a direct replacement tub assembly that provides reliable, efficient washing performance and long service life. IMPORTANT: This is a complete tub assembly that includes the transmission, motor, and belt—verify all components are included in the package before installation. CRITICAL: This is a major repair that requires complete washer disassembly and reassembly. If uncomfortable with this repair, hire a qualified appliance technician.
