WP21366 Whirlpool Spanner Nut

The Spanner Nut is a genuine OEM (Original Equipment Manufacturer) component designed for use in Whirlpool washing machines. This part plays a vital role in attaching the washer tub firmly to the drive shaft, which is essential for the stability of the tub during both washing and spinning processes. Maintaining this stability is important not only for the machine's efficient operation but also for its durability, as it helps to minimize vibrations and maintain balance.

It is advisable to replace the spanner nut if you notice it has become loose or shows signs of stripping. Common reasons for deterioration of the spanner nut include over-tightening, normal wear and tear, or damage due to excessively heavy loads. Additionally, prolonged exposure to moisture and detergent can cause the nut to corrode, which may affect its effectiveness in securing the tub.

Indications that the spanner nut may need to be replaced include:

- Unusual vibration or shaking during the wash cycle
- Noticeable banging or knocking sounds
- The washer tub appearing loose or misaligned
- Water leaking around the tub area

This component is compatible with a range of models from Whirlpool and its affiliated brands, including Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore.
