What To Know
- The pressure switch monitors the water level in the washing machine and signals when the machine is full.
- If the drain hose is blocked, it can prevent water from draining from the washing machine, causing the machine to hum but not fill with water.
- If the water inlet valve is clogged or damaged, you may hear a humming sound but no water will enter the washing machine.
If your washing machine is humming but not filling with water, it can be a frustrating experience. This problem can stem from various reasons, ranging from simple fixes to more complex repairs. In this comprehensive guide, we will delve into the underlying causes of why your washing machine is humming but not filling with water and provide step-by-step troubleshooting solutions.
Causes of a Humming but Not Filling Washing Machine
1. Clogged Water Inlet Valve
The water inlet valve is responsible for controlling the flow of water into the washing machine. If it becomes clogged with debris or sediment, it can prevent water from entering the machine.
2. Faulty Water Pressure
Insufficient or excessive water pressure can cause the washing machine to hum but not fill with water. The ideal water pressure for most washing machines is between 40 and 60 psi.
3. Kinked or Crushed Inlet Hose
The inlet hose connects the water supply to the washing machine. If the hose is kinked or crushed, it can restrict the flow of water.
4. Defective Pressure Switch
The pressure switch monitors the water level in the washing machine and signals when the machine is full. If the pressure switch is faulty, it may not send the correct signal to the washing machine, preventing it from filling with water.
5. Malfunctioning Control Board
The control board is the brain of the washing machine. If it malfunctions, it can disrupt the communication between different components, including the water inlet valve and pressure switch.
6. Worn-Out Water Pump
The water pump is responsible for draining water from the washing machine. If the pump is worn out or damaged, it may interfere with the filling process.
7. Blocked Drain Hose
If the drain hose is blocked, it can prevent water from draining from the washing machine, causing the machine to hum but not fill with water.
Troubleshooting Steps
1. Check the Water Supply
Ensure that the water supply is turned on and that the water pressure is within the recommended range.
2. Inspect the Inlet Hose
Examine the inlet hose for any kinks, crushes, or damage. If the hose is damaged, replace it with a new one.
3. Clean the Water Inlet Valve
Remove the water inlet valve and clean it with a vinegar solution or a commercially available cleaning agent.
4. Test the Pressure Switch
Disconnect the pressure switch from the washing machine and use a multimeter to test its continuity. If the pressure switch is faulty, replace it.
5. Reset the Control Board
Unplug the washing machine from the power outlet for 30 minutes. This will reset the control board and may resolve the issue.
6. Inspect the Water Pump
Remove the water pump and check for any damage or wear. If the pump is faulty, replace it.
7. Unblock the Drain Hose
Disconnect the drain hose from the washing machine and remove any blockages.
The Bottom Line: Resolving the Humming Washing Machine
By following the troubleshooting steps outlined in this guide, you can identify the underlying cause of why your washing machine is humming but not filling with water. With a bit of patience and the right tools, you can resolve the issue and get your washing machine back to working order.
