How should I troubleshoot and address noise or vibration in my washing machine?

Troubleshooting and addressing noise or vibration in my washing machine

1. Check the installation environment and levelness
Make sure the washing machine is placed on a hard, flat, and clean surface to avoid tilting or uneven surfaces that could cause resonance.
Adjust the four corner feet to ensure even load on all four legs and prevent shaking.
2. Check the internal load and clothing distribution
Unnecessary or uneven clothing can cause the drum to become unbalanced, leading to severe vibration.
Add clothing or rearrange the load appropriately to evenly distribute the weight inside the drum.
3. Check for wear or looseness in key components
Shock absorber springs and elastic supports: Aging springs or failed supports can amplify noise.
Drive belts and bearings: Loose belts or worn bearings can cause unusual noise and require tightening or replacement.
Drain pump and filter: Obstructed foreign objects or loose filters can also cause noise and vibration.
4. Check the water inlet and drainage systems
Check whether the water inlet valve is open too far. Excessive water pressure can cause noise; reduce the valve opening if necessary. Make sure the drain hose is not flattened or blocked to prevent water flow obstruction and pounding sounds.

How is washing machine capacity calculated, and how can I avoid overloading?

1. Definition of Rated Washing Capacity
Rated capacity refers to the maximum weight of dry laundry that can be washed in one cycle, measured in kilograms

For example, a washing machine with a rated capacity of 5.5 kg can handle a maximum of 5.5 kg of dry laundry.
2. Capacity Calculation Formula
According to GB/T4288-2003, the ratio of rated wash water volume to rated washing capacity satisfies the formula:
C=V/m
C: The amount of water required per kilogram of laundry, measured in L/kg. A lower value indicates a more water-efficient washing machine.
V: The rated wash water volume indicated in the manual, measured in L, refers to the total amount of water used in a standard wash cycle.
m: The rated wash capacity, measured in kg, refers to the maximum weight of laundry that the washing machine can wash in one cycle (e.g., 8 kg).

3. Key Operational Tips to Avoid Overloading

Adhere to the weight limit: Before loading laundry, estimate the weight of dry laundry to ensure it does not exceed the rated capacity.

Wash in batches: Wash large or heavy items (such as blankets and down jackets) in batches or use the high-load mode to avoid overloading at once.

Observe the machine's operating status: If unusual vibrations or noises occur, the load may be approaching or exceeding the maximum load limit. Reduce the load immediately.

4. Impact of Overloading on the Machine

Overloading can cause drum imbalance, increase bearing wear, and shorten its service life.

It also increases the load on the motor, leading to increased energy consumption and even triggering a power outage.
