What the F23 Error Code Means
The F23 error code indicates a fault with the pressure sensor (also known as the water level sensor or FWL sensor). This sensor monitors the water level in the drum by detecting air pressure in a small chamber connected to the drum. When the sensor readings fall outside the expected range, the machine stops the programme and displays F23.
Common Reasons This Error Appears
Blocked or kinked pressure sensor hose
The small air hose connecting the pressure sensor to the drum can become blocked with detergent residue or kinked, causing inaccurate pressure readings.
Faulty pressure sensor
The pressure sensor itself may have failed and is no longer providing accurate water level readings to the control board.
Blocked air chamber
The air chamber connected to the pressure sensor can become partially blocked with detergent residue or debris, affecting pressure readings.
Wiring fault
A loose or damaged connection between the pressure sensor and the control board can disrupt signal transmission and trigger this error.
Safe Checks You Can Try
Check the pressure sensor hose
Locate the small rubber hose running from the pressure sensor to the drum. Check it for any kinks, blockages or detachment. Clear any blockages by blowing gently through the hose or replacing it if damaged.
Check the drain hose position
Ensure the drain hose end is positioned correctly — between 60cm and 100cm above floor level. An incorrectly positioned drain hose can cause siphoning that affects pressure sensor readings.
Restart the washing machine
Switch the machine off at the mains and leave it unplugged for a few minutes. Reconnect the power, switch back on and restart the programme. A power reset can sometimes clear a temporary sensor fault.
