Washer does not fill with water or fills very slowly; no error code displayed.

Safety first: Unplug the washer and turn off both hot and cold water valves.

Check external supply:

• Verify that both supply valves are fully open.
• Disconnect hoses from the back of the washer and run them into a bucket to confirm strong water flow from the house plumbing.

Clean inlet screens:

• Inspect the small screens inside the washer's inlet valve ports. Remove debris with a soft brush; do not damage the screens.

Test inlet valve:

• With the washer unplugged, measure resistance across each valve coil. Replace the water inlet valve assembly if a coil is open or if the valve does not open when energized (live testing should be done only by trained personnel).
