Clean the Water Inlet Hose Mesh Filter

Safety Precautions: Ensure the appliance is powered off and the water supply faucet is completely closed before starting. Have a towel or small basin ready to catch residual water remaining in the hose.

Tools Needed: Pliers (if the coupling is overtightened) and a clean water source.

Steps:

1. Turn off the water supply at the household faucet.
2. Unscrew the water inlet hose coupling from the faucet connection.
3. Carefully remove the small mesh screen filter located inside the hose coupling, using pliers if necessary.
4. Rinse the mesh filter thoroughly under running water to remove all sediment, sand, and mineral deposits.
5. Reinsert the clean filter into the hose coupling.
6. Reconnect the hose to the faucet and tighten it securely by hand.
7. Turn the water supply back on and check for any leaks at the connection point.
8. Run a short cycle on the appliance to verify that the F12 error has been cleared.
