Possible causes of err8 error code:

• Faulty pressure sensor: 
  • The sensor responsible for measuring water level might be malfunctioning, leading to inaccurate readings and the machine overfilling.
• Blocked drain hose or filter: 
  • If the drain is clogged, water might not be properly pumped out, causing the machine to keep filling and triggering the error.
• Faulty inlet valve: 
  • In rare cases, the valve that controls water flow into the machine might be malfunctioning, leading to overfilling.
• Control board issue: 
  • Less commonly, the error could indicate a problem with the control board itself, misinterpreting signals from the pressure sensor or sending incorrect commands to the inlet valve.
