A humming sound during the water filling cycle of your washing machine is usually caused by the water inlet valve. This valve controls the flow of water into the machine, and a faulty valve can create a humming noise.
Here are some potential reasons why your washing machine hums when filling with water:
1. Clogged Water Inlet Valve:
- The water inlet valve can become clogged with debris, such as sediment or mineral deposits. This blockage can restrict water flow, causing the valve to hum.
- Solution: Try cleaning the water inlet valve. You can find instructions on how to do this in your washing machine's manual or online.
2. Worn-Out Water Inlet Valve:
- Over time, the water inlet valve's internal components can wear out, leading to a humming sound.
- Solution: Replacing the water inlet valve is usually the best solution in this case.
3. Faulty Water Pressure:
- Low water pressure can cause the water inlet valve to work harder, resulting in a humming noise.
- Solution: Check your home's water pressure. If it's too low, you might need to adjust your plumbing or contact a plumber.
4. Electrical Issues:
- In rare cases, electrical issues with the water inlet valve or the washing machine's control board can cause a humming sound.
- Solution: It's best to consult a qualified appliance technician for this issue.
It's important to note that these are just some common reasons for a washing machine humming during water filling. If you're unsure about the cause, it's always best to contact a qualified appliance repair technician for professional diagnosis and repair.
