Dishwasher Not Rinsing: Fix It Yourself

Quick answer

If your dishwasher isn't rinsing dishes properly, check the rinse aid dispenser and spray arms. Clean the filter and ensure the rinse aid is filled. If the issue persists, inspect the water inlet valve and heating element.

Confirm the symptom

• Dishes remain dirty after a full cycle
• Water droplets or suds remain on dishes
• Spray arms do not spin during the cycle
• Rinse aid light is blinking or flashing
• Water pressure seems low during the cycle

Tools and prep

• Screwdriver (flathead or Phillips, depending on model)
• Soft brush or toothbrush
• White vinegar or dishwasher cleaner
• Clean cloth or towel
• Safety gloves
• Turn off power to the dishwasher at the circuit breaker
• Shut off water supply if working on inlet valve

Step-by-step troubleshooting

1. Check Rinse Aid Level
   Do: Open the rinse aid dispenser and check if it's empty or low.
   Observe: Empty or low rinse aid level
   Means: Rinse aid helps water sheet off dishes. Low levels can cause suds or spots.
   Next: Refill the rinse aid container and run a test cycle.
2. Inspect Spray Arms
   Do: Remove the lower and upper spray arms (if applicable) and check for clogs.
   Observe: Clogged or blocked spray arm holes
   Means: Clogs prevent proper water distribution and rinsing.
   Next: Clean the spray arms with a brush and water. Reinstall and test.
3. Clean the Filter
   Do: Locate and remove the dishwasher filter (usually at the bottom of the tub).
   Observe: Dirty or clogged filter
   Means: A clogged filter restricts water flow and affects cleaning/rinsing.
   Next: Rinse the filter under running water and reinstall it.
4. Check Water Inlet Valve
   Do: Listen for the water inlet valve to activate at the start of the cycle.
   Observe: No sound or weak water flow into the dishwasher
   Means: A faulty valve prevents proper water intake for rinsing.
   Next: Test the valve with a multimeter or call a professional.
5. Test Heating Element
   Do: Check if the heating element turns on during the cycle.
   Observe: Heating element does not glow or heat water
   Means: A failed heating element can cause poor rinsing due to cold water.
   Next: Use a multimeter to test for continuity or replace the element.
6. Inspect Water Pressure
   Do: Check the home's water pressure or look for kinks in the inlet hose.
   Observe: Low water pressure or kinked hose
   Means: Inadequate water pressure affects spray arm performance.
   Next: Straighten the hose or adjust the home's water pressure.
