DIAGNOSUS A slow fill is almost always a problem with the water inlet valve screens being clogged with sediment or mineral deposits from your home’s water supply.
How to Fix It
Turn off the hot and cold water supply valves behind the machine. Disconnect both fill hoses from the back of the washer. Check the small mesh screens inside the hose connections on the machine’s valve inlets. You’ll see them. Use needle-nose pliers or tweezers to gently pull them out. Rinse them under water and scrub lightly with an old toothbrush to remove any gunk. Reinsert the screens, reconnect the hoses, and turn the water back on. The fill rate should be back to normal.
If That Didn't Work
If the screens were clean, the problem might be in the hoses themselves or the household water valves. Check that both supply valves are fully open. You can also detach the hoses from the wall valves and run them into a bucket to see if the flow is strong there, which would point to the machine’s valve as the culprit.
Heads Up
If you have particularly hard water, you’ll need to clean these screens every 6-12 months as part of regular maintenance. It’s the most common cause of fill issues on any washer.
