Unplug the washer for 1 minute, then plug it back in. If the error persists, fix the underlying water supply issue before using the washer again.

Turn off water supply, unplug the washer, disconnect the hoses, and remove the small mesh screens from the valve ports. Rinse them with water and scrub gently with a toothbrush.

If it's a simple fix (e.g., cleaning screens or turning on valves), it's free. Replacing the water inlet valve costs $20-$50 for the part plus $100-$200 for professional labor.
