Possible Meanings of error EF4:

• Flow meter issue: 
  • This is the most common meaning of the EF4 error code. It indicates that the flow meter, which measures the water entering the machine, is not detecting any water flow even though the water inlet valves are open.
• Inlet valve issue: 
  • In some cases, the EF4 error might signify a problem with the water inlet valves themselves, preventing water from entering the machine.
• Wiring or connection problem: 
  • Damaged or loose wiring between the flow meter, water inlet valves, and control board can disrupt communication and cause the EF4 error.
• Control board issue: 
  • In rare cases, the main control board might be malfunctioning and misinterpreting sensor readings, leading to the EF4 error.
