Understanding the Problem
Brief explanation: The WPW10238100 is the water inlet valve assembly used on many Whirlpool/KitchenAid/Maytag refrigerators. It opens and closes electrically to let household water into the ice maker and water dispenser. When it fails, you’ll lose water flow, have slow fill times, get no ice, or see leaks. Step-by-step diagnostic and repair instructions: 1) Confirm symptoms: Try the water dispenser and initiate a harvest or fill cycle on the ice maker. Note whether there is any water flow, a clicking sound from the valve, or visible leaks at the valve. 2) Turn off power and water: Unplug the refrigerator (or flip the breaker) and shut off the water supply to the fridge before any inspection or repair. 3) Access the valve: Move the fridge away from the wall. The valve is usually mounted at the rear lower-left or -right behind an access panel. Remove the panel screws and set the panel aside. 4) Inspect visually: Look for leaking connections, cracked plastic, or mineral buildup on the inlet screens. Check that the tubing is seated and not pinched or frozen. 5) Check electrical: With the power off, unplug the electrical connector from the valve and inspect for corrosion or melted plastic. With a multimeter set to continuity/ohms, check each solenoid coil for continuity (both coils should show continuity). A completely open coil indicates a failed solenoid. 6) Check water supply: Ensure the water shutoff valve at the house is open and there is water pressure. Disconnect the inlet tube from the valve into a bucket briefly (after turning water back on) to confirm actual water supply to the valve (do this only if you re-energize water and keep power off). 7) Replace the valve if faulty: If the valve is cracked, leaking, or a solenoid coil has failed (no continuity), replace the WPW10238100 valve. If the valve clicks but no water flows, screens may be clogged or inlet supply is blocked — consider cleaning or replacing the filter/screen and checking home water pressure. 8) Replacement steps (high level): a) Turn off power and water. b) Remove access panel and note tubing/electrical connections. c) Label and disconnect electrical connectors. d) Loosen or remove the water tubing (have rag/bucket ready). e) Remove mounting screws and swap valves. f) Reconnect tubing (use new ferrules/washer if provided) and electrical connectors. g) Turn water back on slowly and check for leaks. h) Restore power and run dispenser/ice maker to verify operation. Safety note: Always disconnect power before doing electrical tests or replacing the valve. If you must apply live voltage to test the valve, only do so if you’re experienced and take appropriate precautions; applying mains voltage incorrectly can be dangerous. If unsure, hire a qualified technician.
Common Symptoms
No water from the dispenser, ice maker not filling or making ice, slow fill of ice maker or dispenser, water leaking at or under the fridge, or the valve clicks but water does not flow.
Common Causes
- Failed solenoid coil (electrical failure) inside the inlet valve
- Clogged inlet screens or sediment blocking flow
- Cracked plastic valve body or leaking connections
- No/low household water pressure or closed supply valve
- Frozen water line in the refrigerator door or inlet tube

Helpful Repair Tip
Listen for a faint click when you activate the dispenser or ice maker—no click plus no continuity on a multimeter usually means a bad solenoid valve. Also test water supply by briefly disconnecting the inlet tube and opening the house valve to confirm pressure.
Frequently Asked Questions
How do I test if WPW10238100 is bad?
First, verify the water supply is on and there’s no frozen line. Unplug power and remove the valve access panel. Use a multimeter to check each solenoid coil for continuity—an open coil (infinite resistance) usually means failure. Reapply power only if you’re experienced: when the dispenser or ice maker calls for water you should hear the valve click. If it clicks but no water flows and the supply is good, the valve or internal screens may be clogged or damaged and require replacement.
Can I replace the WPW10238100 myself and how hard is it?
Yes—this is a common DIY repair and is moderate in difficulty. You’ll need basic tools: screwdriver, pliers, and possibly a wrench for the water line. Key steps: shut off power and water, remove the rear access panel, label and disconnect electrical connections and tubing, remove mounting screws, install the new valve, reconnect tubing and electrical plugs, turn water on and check for leaks, then restore power and test. If you’re uncomfortable working with water lines or electrical connections, call a professional.
