LG Dishwasher Dishwasher Water Inlet Valve 5221DD1001F

🇺🇸 Matching U.S. Part Number: 5221DD1001F

Is This the Right Part?

Confirm the complete model number before ordering. Similar parts may use different connectors, dimensions, hose positions, electrical ratings, or mounting points.

• Dishwasher not filling with water — cycle runs but tub stays dry
• Dishwasher fills very slowly
• IE or water-inlet error code displayed
• Humming during fill phase without water entering the tub
• Water leaking around the valve body or connections
• Insufficient water for proper washing — dishes come out dirty or with detergent residue
• Water entering the dishwasher when the valve should be closed

• Confirm the household water shutoff valve under the sink is fully open
• Check that the supply hose is not kinked, pinched or blocked
• Inspect the mesh screen at the valve inlet for sediment or mineral buildup — a clogged screen can restrict flow and trigger the same error without valve failure
• Verify household water pressure is adequate — low pressure can prevent the valve from opening fully
• Check the float and overfill switch — a stuck float can prevent the fill cycle from starting
• Confirm the door latch is engaging fully — the control will not initiate a fill cycle without a confirmed door signal
• Inspect wiring and connector at the valve for corrosion, looseness or damage

1. Disconnect electrical power and shut off the household water supply before service.
2. Photograph the valve orientation, hose routing and wiring connections before disconnecting anything.
3. Compare the replacement valve with the original before installation — confirm mounting, hose connections and connector positions match.
4. Inspect the supply hose and inlet screen for damage or buildup while the valve is out.
5. Reconnect all water connections and check for leaks before reinstalling the access panel.
6. Restore power and run a short fill cycle to confirm correct operation and verify no leaks.

The LG 5221DD1001F is a genuine LG dishwasher water-inlet-valve assembly. It replaces discontinued LG part numbers 5221DD1001A and 5221DD1001B.

The electrically operated valve opens during the dishwasher fill phase to admit household water into the appliance. Published specifications identify it as a 120-volt, 60-hertz component. A failed, restricted or leaking valve may contribute to a dishwasher that will not fill, fills slowly, displays a water-inlet error, hums without admitting water, or leaks around the valve area.

Similar symptoms can also result from a closed household shutoff valve, low water pressure, kinked supply hose, restricted inlet screen, float-system problem, damaged wiring, door-latch fault or electronic-control failure. Confirm the valve diagnosis and exact dishwasher model before ordering.

Confirm the complete dishwasher model before ordering. Similar-looking valves may differ in mounting, hose connections, electrical connectors or flow characteristics.

Confirm the complete model number, including suffixes and revision digits, before ordering. Similar valves may use different mounting positions, hose diameters, connector types or flow ratings.
