Step 1: Inspect and Clean the Spray Arm

The spray arm is crucial in the dishwasher’s cleaning process. If it’s clogged or damaged, it could be the reason your top dishwasher rack is not cleaning. Here’s how you can inspect it:

  1. Unplug the dishwasher to ensure safety.
  2. Locate the spray arm, typically situated at the bottom of the dishwasher.
  3. Check for visible clogs or damage. Small pieces of food or other debris can easily get stuck.
  4. Remove the spray arm, following your dishwasher’s specific model instructions.
  5. Once removed, clean the spray arm by running it under warm water and gently using a soft brush to dislodge any clogs.
  6. Once cleaned, reinstall the spray arm and plug the dishwasher back in.

Step 2: Examine the Filter

A dirty or damaged filter can affect water flow, causing the dishwasher not cleaning the top rack. To examine the filter, follow these steps:

  1. Unplug the dishwasher and remove the bottom dish rack to get to the filter.
  2. Inspect the filter for damage or excessive dirt. If it’s merely dirty, you can clean it.
  3. To clean, rinse the filter under warm water and use a soft brush to scrub off any debris.
  4. If the filter is damaged, replace it with a new one that is compatible with your dishwasher model.

Step 3: Check the Water Inlet Valve

The water inlet valve controls the water entering your dishwasher. If it’s defective, it might result in the top rack not being cleaned properly. Here’s how to inspect it:

  1. Unplug your dishwasher and locate the water inlet valve. This is usually situated at the bottom of the dishwasher.
  2. Check for any visible signs of damage. If it’s visibly damaged, you will need to replace it.
  3. If it’s not visibly damaged but you suspect it’s not working correctly, you may need a multimeter to test it for continuity. If the valve fails the test, it needs to be replaced.

Step 4: Examine the Detergent Dispenser

If the detergent dispenser is not working properly, this could lead to the dishwasher not cleaning the top rack. Here’s how you can check the detergent dispenser:

Run your dishwasher on a normal cycle and observe if the detergent dispenser opens. If it doesn’t open during the cycle, it needs to be replaced.
