When Do These Error Codes Occur

9E1 and 9E2 Error Codes:

1. Occurs When: The 9E1 and 9E2 error codes typically occur when there is a water supply issue during the washing machine's operation.
2. Possible Causes:
   • Insufficient water supply (potential causes include low water pressure from the source, partially closed water supply valves, kinks or restrictions in the water supply lines).
   • Water inlet valve problems (potential causes include blockage or debris in the water inlet valve or valve failure due to wear or electrical issues).
   • Water pressure issues (potential causes include sensor failure to accurately detect water pressure or problems with the communication circuit between the sensor and the control board).
3. What parts of the washing machine are responsible for these error codes?

Understanding the specific components tied to each error code is essential for effective diagnosis and resolution.
