Does your washing machine sound like a plane taking off? Does your refrigerator make strange noises in the middle of the night? Excessive noise from appliances is one of the most common complaints in modern homes. While all appliances generate some level of sound during operation, unusual noise may indicate a lack of maintenance, incorrect installation, or even a developing technical failure.
In this article, we’ll share the most common causes of appliance noise and the best techniques to reduce or eliminate it entirely.
Why do appliances make noise?
Before applying solutions, it’s important to understand why an appliance may be louder than usual. The most common causes are:
- Loose or misaligned components.
- Worn parts (bearings, motors, fans).
- Vibrations due to poor installation.
- Internal obstructions.
- Lack of preventive maintenance.
Techniques to reduce noise at home
- Properly level the appliance
One of the main causes of vibration and noise in washers, dryers, and refrigerators is that they are not level.
Solution: Use a bubble level to ensure the appliance is stable on a flat surface. Adjust the legs or base as needed.
Tip: If the floor is uneven, place a non-slip rubber mat to absorb the vibrations.
- Install anti-vibration pads
These rubber or foam pads are placed underneath the appliance and help absorb movement.
Ideal for: Washing machines, dryers, dishwashers, and refrigerators.
Additional benefit: They also protect your floors from scratches.
- Perform regular maintenance
Noise may come from dust, lint, or grease buildup on internal components like fans, bearings, or filters.
Solution: Clean filters, inspect hoses, and ventilate the motors every 3 to 6 months.
Important: If the appliance is over a year old, annual preventive technical maintenance is recommended.
- Tighten loose screws and parts
With use, some screws, covers, or internal components may loosen and cause vibrating noises.
How to do it: Turn off and unplug the appliance. Use a wrench or screwdriver to check that all connections are secure—without overtightening.
- Avoid overloading the appliance
An overloaded washer or dryer can become unbalanced and cause loud banging or rattling.
Recommendation: Always follow the manufacturer’s guidelines on maximum load capacity.
- Consult a professional if the noise persists
If the noise continues or gets worse after applying these techniques, it may be due to:
- Worn bearings.
- Internal motor faults.
- Misaligned fans.
- Broken parts.
Do not attempt repairs on your own if you don’t have technical experience.
In summary…
Reducing appliance noise is possible with some maintenance and the right tools. However, persistent or unusual noise almost always means something is not working correctly. Paying attention in time can help you avoid major repairs and ensure a more comfortable and safe home environment.
