Possible causes of err5 error code:

• Closed or partially closed water tap: 
  • This is the most common culprit. Ensure both hot and cold water taps are fully open.
• Kinked or blocked water hose: 
  • Check for any bends or obstructions in the hoses connecting the machine to the water supply. Inspect for debris or limescale buildup that might restrict water flow.
• Low water pressure: 
  • If your home has low water pressure, the machine might not be able to fill properly. Check with your local water authority or plumber if you suspect this issue.
• Faulty inlet valve: 
  • In rare cases, the valve that controls water flow into the machine might be malfunctioning.
• Other potential causes: 
  • Less common possibilities include issues with the control board, pressure sensor, or drain hose (if it's connected incorrectly, causing water to siphon out).
