Understanding the Problem
A leaking dual water inlet valve (the valve that feeds both the ice maker and the water dispenser) will drip water under or behind the refrigerator, cause puddles on the floor, and can lead to no/slow water flow for the dispenser or ice maker. The valve can leak from a cracked plastic body, failed internal seals, loose fittings, or a corroded inlet connection. Below are step-by-step diagnostics and repair instructions you can follow. 1) Identify and confirm the leak location - Look for water pooling under or behind the fridge. Place paper towels or cardboard beneath the back left/right corner and run a test dispense/ice harvest to see if fresh drips appear. If water is coming from the valve area at the back bottom of the fridge, the inlet valve is the likely culprit. 2) Shut off power and water - Unplug the refrigerator or switch off its breaker. Locate the water shutoff valve (usually at the wall or under the sink) and turn it off. Leave the refrigerator unplugged while you work. 3) Access the inlet valve - Pull the fridge out from the wall and remove the lower rear access cover (usually held by screws). The dual inlet valve is mounted near the bottom rear with two plastic solenoids and 1/4" water fittings. 4) Inspect visually - Look for cracks, mineral buildup, corrosion, or water pooled around the valve body, fittings, and tubing. Check compression fittings or quick-connects for looseness. 5) Test the solenoids electrically - Disconnect the wiring harness from the valve. Use a multimeter to measure continuity across each solenoid coil. Typical coil readings are in the hundreds to low thousands of ohms (model-dependent). If a coil is open (infinite ohms) the solenoid has failed. 6) Isolate supply and check fittings - With water still off, place a towel under the valve and loosen the compression fittings or push-fit tubing to see if a leak is from a hose/connection rather than the valve body. A leaking fitting may be fixed by reseating or replacing the ferrule/insert and tightening properly. 7) Replace the valve if necessary (how to fix) - Tools: pliers, adjustable wrench, nut driver/screwdriver, bucket, replacement valve, towels. - Steps: a) Turn off water and power (again) and place a bucket under the valve. b) Disconnect wiring harness from valve and label wires if needed. c) Loosen and remove the inlet water tubing (1/4" compression or quick-connect) and the outlet lines to ice maker/dispenser. d) Remove mounting screws and pull the old valve out. e) Install the new valve: mount it in place, reconnect tubing (hand-tighten compression nuts then 1/4 turn with wrench — don’t overtighten), reconnect quick-connect tubing fully, and plug the harness back in. f) Turn water back on slowly and check for leaks at all connections. If compression fittings leak, tighten a little more. If quick-connects leak, remove and re-seat tubing with a clean square cut. g) Plug the refrigerator back in and run a dispenser/ice maker test to confirm proper flow and no leaks. 8) Final checks - Monitor for 30 minutes after repair for any slow leaks. Run a few dispenser cycles to purge air and check water clarity. Safety note: Always disconnect power before working on electrical components. Turn off the water supply to avoid flooding. If you are not comfortable working with water lines or electrical testing, call a qualified appliance technician.
Common Symptoms
Puddles under or behind fridge, dripping at the rear bottom, reduced or no water from dispenser or ice maker, intermittent operation, or loud buzzing at the valve.
Common Causes
- Cracked or brittle plastic valve body allowing water to leak
- Worn or damaged internal seals/diaphragms in the valve
- Loose or damaged compression/quick-connect fittings
- Sediment/debris clogging valve seat or causing a seal failure
- Corroded inlet connection or freeze damage to supply line

Helpful Repair Tip
Turn off water and remove the outlet tubing from the valve into a bucket—if the valve body still leaks when tubing is removed, the valve body itself is failing. Also check solenoid coil continuity with a multimeter; open coils mean replace the valve.
Frequently Asked Questions
Can I repair the leak without replacing the entire valve?
Sometimes: if the leak is from a loose compression fitting or a damaged tubing seat, reseating the tubing, replacing the ferrule/nut, or replacing the small O-ring (if serviceable) can stop the leak. However, most leaks are caused by cracked valve bodies or failed internal seals, and in those cases replacing the entire valve assembly is the reliable fix.
How long does replacement take and how much will it cost?
A DIY replacement typically takes 20–60 minutes. Parts cost for an OEM-style dual inlet valve usually ranges $40–$120 depending on model and supplier. If you hire a technician, add labor (often $75–$150). Always verify the correct replacement part for your refrigerator model number before purchasing.
