Dishwasher Not Pumping Water Into Machine

Quick answer

If your dishwasher isn't pumping water, first check the water supply valve and filter. Ensure the float switch isn't stuck and the inlet valve is working. Clean or replace clogged parts as needed.

Confirm the symptom

• No water enters the dishwasher during fill cycle
• Dishes remain dirty after a complete cycle
• You hear the dishwasher run but no water flows in
• Water pressure seems low in the kitchen sink
• The dishwasher starts but immediately stops

Tools and prep

• Screwdrivers (flathead and Phillips)
• Adjustable wrench
• Flashlight
• Plumber's putty or Teflon tape
• Replacement water filter (if needed)
• Bucket (to catch water if needed)
• Turn off power at the circuit breaker
• Shut off the water supply to the dishwasher

Step-by-step troubleshooting

1. Check Water Supply Valve
   Do: Locate the shutoff valve near the dishwasher and ensure it is fully open.
   Observe: Valve handle is parallel to the pipe.
   Means: Valve is open if aligned with the pipe.
   Next: If closed, open it and run a test cycle.
2. Inspect Inlet Valve
   Do: Use a multimeter to test the inlet valve for continuity.
   Observe: No continuity indicates a faulty valve.
   Means: Valve is defective and needs replacement.
   Next: Replace the inlet valve if faulty.
3. Clean Water Filter
   Do: Remove the water filter from the bottom of the dishwasher and clean it under running water.
   Observe: Filter is free of debris and sediment.
   Means: Clogged filter was restricting water flow.
   Next: Reinstall the filter and test the dishwasher.
4. Check Float Switch
   Do: Look inside the dishwasher to see if the float switch is stuck in the up position.
   Observe: Float is stuck or debris is preventing movement.
   Means: Stuck float is preventing the fill cycle.
   Next: Clean the area around the float and reset it manually.
5. Test Water Pressure
   Do: Check the water pressure at the kitchen sink using a pressure gauge.
   Observe: Pressure is below 20 psi or fluctuates significantly.
   Means: Low water pressure is affecting the dishwasher.
   Next: Contact a plumber if pressure is consistently low.
6. Inspect Hoses and Connections
   Do: Check the inlet hose for kinks, cracks, or loose connections.
   Observe: Hose is damaged or connections are leaking.
   Means: Damaged hose or loose connections are blocking water flow.
   Next: Replace the hose or tighten connections.

Common causes

Parts matching

Common parts needed for a dishwasher not pumping water include:

• Water Filter – Clogs can restrict water flow.
• Inlet Valve – Controls water entry into the dishwasher.
• Inlet Hose – Connects the water supply to the machine.
• Float Switch – Prevents overfilling by sensing water level.
• Water Pump – Circulates water during the wash cycle.

Purchase OEM parts for compatibility and reliability.

When to call a professional

• The inlet valve test shows no continuity and you're uncomfortable replacing it yourself
• Water pressure is consistently below 20 psi despite checking the supply line
• The dishwasher still doesn't fill after replacing the filter, hose, and inlet valve
• You suspect a failed control board or water pump
• There are signs of water leakage or electrical issues
• You hear unusual noises during the fill cycle that persist after troubleshooting
