Possible causes

• Faulty level sensor: 
  • The sensor itself might be damaged or malfunctioning, providing inaccurate readings.
• Wiring issues: 
  • Damaged or loose wiring connections to the sensor could be affecting its ability to communicate with the control board.
• Blocked pressure hose: 
  • The small hose that connects the sensor to the tub might be obstructed, preventing accurate water level readings.
• Control board problems: 
  • In rare cases, the control board might be faulty and unable to process sensor readings correctly.

Troubleshooting the E7 Error Code

1. Try a hard reset:
   • Disconnect the washing machine from power for at least 30 minutes. This can sometimes clear temporary glitches or errors.
   • Reconnect the power and try running a cycle. If the error persists, proceed to further troubleshooting.
2. Check the pressure hose:
   • Locate the small hose connecting the level sensor to the tub, usually found at the bottom rear of the machine.
   • Ensure it's clear of any blockages or kinks.
3. Inspect the sensor and wiring:
   • Disconnect power and carefully examine the sensor and its wiring for any signs of damage or loose connections.
4. Test the sensor (if you have electrical knowledge):
   • Use a multimeter to test the sensor's resistance. If it's faulty, it'll need replacement.
5. Seek professional help:
   • If the issue persists or you're not comfortable with electrical repairs, consult a qualified technician for diagnosis and repair.

Additional Tips

• Avoid overloading: Overloading can affect water levels and potentially strain the sensor.
• Ensure proper installation: Make sure the machine is leveled correctly, as tilting can also affect water level readings.
• Consult your user manual: Refer to your specific model's manual for any additional troubleshooting advice or error code definitions.
