Washer Keeps Filling with Water

Quick answer

Turn off the washer and water supply immediately. The most common causes are a faulty water valve, broken float switch, or clogged drain. Check these parts first.

Confirm the symptom

• Washer fills with water even when not in use
• Water continues to fill during or after the cycle
• Drain pump runs but water doesn't drain completely
• You hear water running when the washer is idle

Tools and prep

• Power off the washer at the circuit breaker
• Turn off the water supply valves under the washer
• Need a screwdriver, multimeter, and flashlight
• Have replacement parts ready if needed
• Wear rubber gloves and safety goggles

Step-by-step troubleshooting

1. Check Water Supply Valves
   Do: Ensure the valves under the washer are fully closed.
   Observe: Water should stop flowing into the washer.
   Means: Valves were left open or malfunctioning.
   Next: If water still flows, proceed to step 2.
2. Inspect Water Inlet Valve
   Do: Use a multimeter to test the water inlet valve for continuity.
   Observe: No continuity indicates a faulty valve.
   Means: The valve is not closing properly.
   Next: Replace the water inlet valve if faulty.
3. Check Float Switch
   Do: Locate and test the float switch inside the washer tub.
   Observe: Float switch should move freely and trigger when water level is high.
   Means: A stuck or broken float switch prevents the washer from recognizing full water level.
   Next: Replace the float switch if it's faulty.
4. Inspect Drain Pump
   Do: Check the drain pump for clogs or damage.
   Observe: Clogs or damaged pump impede water drainage.
   Means: Water cannot drain properly, causing the washer to refill.
   Next: Clean the drain pump or replace if damaged.
5. Test Pressure Switch
   Do: Use a multimeter to test the pressure switch for continuity.
   Observe: No continuity means the switch is faulty.
   Means: The pressure switch fails to signal the washer to stop filling.
   Next: Replace the pressure switch if faulty.
6. Check for Leaks
   Do: Inspect hoses and connections for leaks or cracks.
   Observe: Leaks or cracks allow water to escape and trigger refilling.
   Means: Water loss is causing the washer to refill unnecessarily.
   Next: Repair or replace damaged hoses and connections.
