Dishwasher Not Going Into Wash Cycle

Quick answer

If your dishwasher won't start the wash cycle, first check the door latch and power supply. Then inspect the control panel and water inlet valve. Reset the dishwasher and test for basic issues before replacing parts.

Confirm the symptom

• Dishwasher fills with water but doesn't start washing
• Control panel shows no error but cycle doesn't advance
• Dishwasher starts but stops before wash phase
• Washer runs rinse cycle but skips wash
• No water sprays during the wash cycle

Tools and prep

• Screwdrivers (flathead and Phillips)
• Multimeter (for testing electrical components)
• Flashlight
• Rubber gloves
• Plumber's tape
• Empty dishwasher to access components
• Turn off power at circuit breaker
• Shut off water supply to dishwasher

Step-by-step troubleshooting

1. Check Door Latch
   Do: Inspect the door latch mechanism for damage or misalignment.
   Observe: Door should close securely and trigger the latch switch.
   Means: A faulty latch prevents the dishwasher from starting.
   Next: If latch is damaged, replace it.
2. Verify Power Supply
   Do: Check the circuit breaker and ensure the dishwasher is receiving power.
   Observe: Power indicator lights or control panel should be active.
   Means: A tripped breaker or power outage stops operation.
   Next: Reset the breaker if tripped.
3. Inspect Control Panel
   Do: Look for error codes or unresponsive buttons on the control panel.
   Observe: Control panel should display normal operation indicators.
   Means: A malfunctioning control board can halt the wash cycle.
   Next: Reset the dishwasher using the manufacturer's instructions.
4. Test Water Inlet Valve
   Do: Use a multimeter to test the water inlet valve for continuity.
   Observe: Valve should have continuity; no reading indicates a failure.
   Means: A faulty valve prevents water from entering during the wash cycle.
   Next: Replace the water inlet valve if it's defective.
5. Check Water Supply
   Do: Ensure the water supply valve under the sink is fully open.
   Observe: Water should flow freely when the valve is open.
   Means: A closed or partially closed valve restricts water flow.
   Next: Open the valve fully and test the dishwasher.
6. Examine Float Switch
   Do: Check the float switch for proper movement and cleanliness.
   Observe: Float should move freely without obstruction.
   Means: A stuck float switch can prevent the dishwasher from starting.
   Next: Clean or replace the float switch if necessary.
7. Reset Dishwasher
   Do: Unplug the dishwasher for 1–2 minutes, then plug it back in.
   Observe: Dishwasher should reset and resume normal operation.
   Means: A power reset can clear minor electrical glitches.
   Next: Run a test cycle to see if the issue is resolved.
8. Inspect Motor and Pump
   Do: Listen for unusual noises or check for motor/pump failure.
   Observe: Motor should run smoothly without grinding or humming.
   Means: A failed motor or pump stops the wash cycle.
   Next: Replace the motor or pump if they're not working.
