What the E23 / F23 Error Means
The Aquastop system is a built-in flood protection feature. When water collects in the base of the machine, a float switch is triggered which shuts off the water supply and stops the cycle. The E23 or F23 code is displayed to indicate this has happened.
Common Reasons This Error Appears
Water leak inside the machine
A leaking hose, pump seal, drum bearing or other internal component can allow water to drip into the base tray and trigger the float switch.
Overfilling
If the pressure sensor or water inlet valve is faulty, the machine may overfill and water can escape into the base.
Excessive foam
Using too much detergent or the wrong type can cause excessive foam which can seep into the base and activate the Aquastop.
Leaking door seal
A damaged or worn door seal can allow water to escape during the cycle and find its way into the base.
Safe Checks You Can Try
Check for visible leaks
Turn off the machine and carefully pull it forward. Inspect underneath and around the back for any signs of water or dampness.
Check detergent usage
Ensure you are using the correct type and amount of detergent. Avoid using standard detergent in machines that require low-foam HE detergent.
Allow the base to dry out
If water has collected in the base tray, tilting the machine slightly forward may help it drain away. Leave the machine for a period before attempting to restart.
