Washing machine bearings are essential components that enable the drum to spin smoothly and efficiently, especially during the high-speed spin cycle. They allow the drum to rotate with minimal friction and support the significant weight and dynamic forces created by wet laundry.
Think of bearings as crucial pivot points. Without them, the drum would simply scrape against the machine's structure, making rotation impossible and quickly destroying the appliance.
Why Washing Machine Bearings Fail
When people ask "Why do bearings go on washing machines?", they typically mean "Why do washing machine bearings fail?". Bearings don't last forever; they are wear-and-tear parts that eventually degrade due to constant use and challenging operating conditions.
Several factors contribute to the wear and failure of washing machine bearings. Based on common knowledge and factors influencing lifespan:
- Usage: Just like any mechanical part, more frequent use leads to faster wear and tear. A machine used daily will likely see its bearings fail sooner than one used weekly.
- Load Size: Regularly overloading the machine puts extra strain on the bearings. The increased weight and imbalance during spinning significantly stress the components.
- Water Quality: Hard water can contribute to bearing corrosion. Mineral deposits can also build up, affecting the smooth operation and potentially damaging seals, leading to water ingress which is a major cause of bearing failure.
- Seals: Bearings are protected by seals that prevent water and detergent from reaching the metal parts and lubricant. If these seals fail, water ingress occurs, washing away lubricant and causing the bearings to rust and seize. This is perhaps the most common reason for premature bearing failure.
- Imbalance: Consistently washing unbalanced loads creates excessive vibration and shock on the bearings, accelerating their wear.
- Manufacturing Defects: Less commonly, a bearing might have a manufacturing flaw that causes it to fail prematurely.
Signs of Failing Bearings
Recognizing the signs of failing bearings is important to prevent further damage to the machine. Look out for:
- Loud rumbling or grinding noises during the spin cycle.
- The drum feeling loose or having excessive play when moved by hand.
- Water leaks (often indicates seal failure leading to bearing issues).
- The drum not spinning or spinning intermittently.
Replacing failing bearings is a common repair, although it can be complex depending on the washing machine model.
