A washing machine is a vital part of any household, ensuring clean clothes with minimal effort. However, when it begins to make strange clicking sounds, it can quickly become a source of frustration and concern. Clicking noises are not uncommon, but they should never be ignored. They can indicate various underlying issues that, if left unresolved, could lead to costly repairs or even a complete appliance breakdown. Two of the most frequent culprits are debris caught in the pump or a damaged relay in the control system.
1. Understanding the Clicking Sound
When your washing machine starts producing a clicking noise during the cycle—especially when filling, draining, or spinning—it’s often an early warning sign of mechanical or electrical trouble. Identifying the sound’s origin is the first step toward fixing it.
Some clicks are normal—such as the door lock engaging or the timer advancing through cycles. However, repeated or irregular clicking throughout the wash, rinse, or spin stages suggests a malfunction that requires professional attention.
2. Debris Caught in the Pump
One of the most common mechanical causes of clicking sounds is debris trapped in the drain pump. During each wash cycle, lint, coins, buttons, and other small objects can accidentally find their way into the machine’s drainage system. Over time, these items may become lodged in the pump impeller, obstructing its movement and producing a rhythmic clicking or rattling sound.
Symptoms of a Clogged Pump
- Clicking or rattling sounds during the drain or spin cycles.
- Water not draining completely from the drum.
- Error codes on digital displays indicating drainage problems.
- A burning smell or overheating if the pump is struggling to operate.
How to Prevent Pump Blockages
- Always check clothing pockets before loading the washer.
- Use a mesh laundry bag for small items such as socks or baby clothes.
- Regularly clean the lint filter (if your model has one).
- Run a maintenance cycle with a cleaner to remove soap scum and debris buildup.
If you suspect debris in the pump, avoid running the machine repeatedly, as it can cause the motor to overheat or the pump to fail entirely. It’s best to call a qualified technician to inspect and clean the drainage system safely.
3. Damaged Relay in the Control Board
If the pump is clear and the clicking persists, the issue may be electrical—specifically, a damaged relay on the control board. The relay acts as an electronic switch, regulating power to different components such as the motor, heating element, and valves. When a relay fails or malfunctions, it may click repeatedly as it tries to activate but fails to maintain proper contact.
Signs of a Faulty Relay
- Continuous or irregular clicking even when the washer is idle.
- The machine fails to start certain cycles or stops unexpectedly.
- Inconsistent water filling, draining, or spinning.
- Burn marks or a smell of overheated electronics near the control panel.
A damaged relay can occur due to normal wear, voltage surges, or moisture exposure inside the control housing. Unlike debris in the pump, this is not something that can be fixed through cleaning or resetting. Replacing the control board or individual relay requires specialized tools and electrical knowledge—tasks best left to professionals.
4. Why You Should Act Quickly
Ignoring unusual sounds in your washing machine can result in more serious damage over time. A small piece of debris in the pump can destroy the impeller, leading to water leaks or motor burnout. Similarly, a faulty relay can cause intermittent power failures that damage other components.
Prompt diagnosis and repair not only save you money but also extend your washer’s lifespan and maintain its energy efficiency.
