Step-by-step troubleshooting

1. Check Water Supply Valve
   Do: Locate the shutoff valve near the dishwasher and ensure it’s fully open.
   Observe: Water flows freely through the supply line.
   Means: The valve was closed or partially closed.
   Next: Run a cycle to see if water fills.
2. Inspect Inlet Valve
   Do: Check the inlet valve for clogs or debris using a screwdriver and wrench.
   Observe: Debris or mineral buildup is present.
   Means: Clogged valve is preventing water flow.
   Next: Clean the valve or replace it if damaged.
3. Clean the Filter
   Do: Remove and clean the dishwasher’s filter under the lower rack.
   Observe: Filter is clogged with food particles or debris.
   Means: Clogged filter restricts water flow.
   Next: Rinse the filter and reinstall it.
4. Test Float Switch
   Do: Lift the float switch inside the dishwasher to see if it moves freely.
   Observe: Float is stuck in the raised position.
   Means: Stuck float prevents water from entering.
   Next: Clean or replace the float switch.
5. Check Water Inlet Hose
   Do: Inspect the inlet hose for kinks or blockages.
   Observe: Hose is kinked or has visible cracks.
   Means: Physical obstruction or damage is blocking water flow.
   Next: Straighten the hose or replace it.
6. Verify Power Supply
   Do: Ensure the dishwasher is receiving power by checking the circuit breaker.
   Observe: Breaker is tripped or outlet has no power.
   Means: Electrical issue is preventing the dishwasher from operating.
   Next: Reset the breaker or check the outlet.
