Possible causes

• Water supply issues:
  • Closed water supply valve: Ensure the valve supplying water to the machine is fully open.
  • Kinked or blocked inlet hose: Inspect the hose connecting the water supply to the machine for any kinks, bends, or blockages.
  • Low water pressure: Check for adequate water pressure in your home's plumbing system.
• Faulty inlet valve: 
  • The valve that controls water entry into the machine might be faulty and need replacement.
• Door switch malfunction: 
  • A faulty door switch might prevent the machine from filling if it doesn't sense that the door is fully closed.
• Control board problems: 
  • In rare cases, the control board itself might be malfunctioning and unable to send correct signals to the inlet valve.

Troubleshooting the E4 Error Code

1. Check water supply:
   • Verify that the water supply valve is open and water pressure is sufficient.
   • Inspect the inlet hose for any kinks or blockages and straighten or clear them as needed.
2. Examine the door switch:
   • Ensure the door is properly closed and the switch is functioning correctly.
3. Test the inlet valve:
   • Use a multi-meter to test the inlet valve's resistance. If it's faulty, it'll need replacement.
4. Reset the machine:
   • Disconnect the power for a few minutes, then reconnect and try running a cycle.
5. Consult a technician:
   • If the issue persists, it's best to seek help from a qualified technician to diagnose the root cause and perform necessary repairs.

Additional Tips

• Refer to your user manual: 
  • Consult your model's specific manual for any additional troubleshooting advice or error code definitions.
• Consider the model: 
  • Some Beko models might have slightly different troubleshooting steps for the E4 error, so always refer to the manual for accurate guidance.
