Why Your GE Dishwasher Isn’t Washing Properly – Troubleshooting & Repair Steps

Is your GE dishwasher running but your dishes still come out dirty? This is a common issue we see at American Appliance Repair, and fortunately, it's often fixable with a few key steps. Below, we’ll walk you through the process we use to diagnose and repair dishwashers that aren’t cleaning properly.
Dishwasher Repair
Step 1: Check for Clogged Spray Arms
Over time, food debris and mineral deposits can block the tiny holes in your dishwasher’s spray arms.
What to do:
Remove the spray arms.
Rinse them under warm water.
Use a toothpick or small brush to clear any clogs.
Step 2: Inspect the Filter
A dirty or clogged filter prevents water from circulating properly and can leave food particles on your dishes.
What to do:
Remove the bottom rack.
Unscrew and lift out the filter (usually located at the bottom center).
Rinse it thoroughly under hot water and scrub if needed.
Step 3: Check Water Temperature
GE dishwashers work best with water that’s at least 120°F (49°C). If the water is too cool, the dishwasher may not clean effectively.
What to do:
Run your hot water tap for 30 seconds before starting the dishwasher.
Use a thermometer to check the water temperature.
If it’s too low, consider adjusting your water heater.
Step 4: Use the Right Detergent
Old, clumpy, or cheap detergents can reduce cleaning performance.
What to do:
Make sure you’re using fresh, high-quality detergent recommended for GE models.
If you have hard water, use detergent with a built-in rinse aid or add rinse aid separately.
Step 5: Inspect the Inlet Valve
The inlet valve controls how much water enters the dishwasher. If it’s failing, the dishwasher won’t have enough water to clean properly.
What to do:
Listen during the fill cycle – if it sounds weak or short, the valve may be faulty.
This part usually requires professional testing and replacement.
Step 6: Run a Diagnostic Cycle
Many GE dishwashers have a diagnostic mode to test components.
What to do:
Refer to your model’s manual for how to start diagnostics.
If any error codes appear, contact a technician with the code information.
