How to Fix F23 Error (Step-by-Step)

Turn off the water supply and unplug the washer from the electrical outlet to ensure safety.
Carefully pull the washer away from the wall to access the back panel and water connections.
Locate the Aquastop valve, which is the blue or grey box attached directly to the water faucet.
Inspect the hose and the Aquastop valve for any visible signs of leaks, cracks, or damage.
If a leak is confirmed, the entire Aquastop hose and valve assembly needs to be replaced as it is a single sealed unit.
Unscrew the old Aquastop valve from the faucet and detach the other end of the hose from the washer’s water inlet valve.
Install the new Aquastop hose and valve, ensuring all connections are tight to prevent further leaks.
Turn the appliance off, wait about 2 minutes, then turn it back on.
