Dishwasher Not Cleaning Dishes Properly – Troubleshooting Guide

1. Check the Spray Arms

• The upper and lower spray arms may be clogged or not rotating.

• Large food particles or limescale buildup can block water flow.

Solution: Remove the spray arms and clean them. Make sure all holes are clear.

2. Clean the Filter

• There is a filter at the bottom of the dishwasher.

• A clogged or dirty filter prevents proper water circulation and cleaning.

Solution: Remove the filter, rinse it under running water, and reattach it.

3. Proper Loading of Dishes

• Plates, pots, and glasses may be too close or stacked.

• Water and detergent cannot reach all surfaces.

Solution: Load dishes according to the manufacturer’s instructions.

4. Detergent and Dishwasher Salt

• Use high-quality detergent and, if necessary, dishwasher salt.

• Detergent tablets or powder should be placed correctly and protected from moisture.

Solution: Check the detergent dispenser and use salt suitable for your water hardness.

5. Check Water Temperature

• If the water isn’t hot enough, grease and food residues won’t be removed effectively.

• Usually, 50–60°C (122–140°F) gives good results.

Solution: Check the temperature setting and change the program if necessary.

6. Regular Cleaning and Maintenance

• Lack of regular maintenance reduces machine performance.

Solution: Clean the filter and spray arms monthly, and run a short maintenance cycle with an empty machine.

7. Electronic or Pump Issues

• If the circulation pump or electronic system is faulty, water may not circulate properly.

Solution: Contact a service technician for repair.

? Summary:

• First, check simple things: filter, spray arms, dish arrangement, detergent, and water temperature.

• If the problem persists, the pump or electronic components may be defective.

• Regular cleaning and maintenance ensure dishes come out fully clean.
