Washer displays F20 or F-20, will not fill properly, may time out with little or no water in drum.

Safety first: Turn off water supply and unplug the washer before disconnecting hoses.

Step-by-step:

• Check supply valves: Ensure both hot and cold valves at the wall are fully open. Verify other fixtures in the home have normal pressure.
• Inspect hoses: Turn off valves, remove hoses from the back of the washer, and check for kinks or internal collapse. Replace if damaged.
• Clean inlet screens: Look inside the water inlet valve ports on the washer for small screens. Remove debris with a small brush; do not puncture the screens.
• Verify temperature selection: Make sure the selected cycle uses the available water supplies (e.g., if hot water is off, avoid hot-only fills).
• Test fill: Reconnect hoses, turn on water, plug in the washer, and run a fill test. If valves click but no water enters, the inlet valve assembly may be faulty.
• Replace inlet valve: If cleaning screens and verifying supply does not restore fill, replace the water inlet valve assembly with the correct Maytag part.
