If you’ve noticed that the upper rack of your dishwasher not cleaning properly, you’re not alone. This is a common issue that many homeowners face, but the good news is that it’s usually easy to fix. In this guide, we’ll walk you through step-by-step solutions to get your dishwasher back in top shape.

Why Is the Upper Rack of Your Dishwasher Not Cleaning?
Before diving into the solutions, it’s important to understand why this problem occurs. The most common reasons include clogged spray arms, a malfunctioning water inlet valve, or even just incorrect loading of dishes.
Step 1: Check the Spray Arms
The spray arms are crucial for effective cleaning. If they’re clogged, the water won’t reach the dishes properly.
- Turn off and unplug your dishwasher.
- Open the dishwasher and pull out the upper rack.
- Locate the spray arms and inspect them for clogs.
- If you find any debris, use a toothpick to carefully remove it.
- Run water through the spray arms to ensure they’re clear.
- Reassemble and test your dishwasher.
Step 2: Examine the Water Inlet Valve
The water inlet valve controls the water supply to your dishwasher. If it’s faulty, the upper rack may not get enough water for cleaning.
- Turn off the water supply to your dishwasher.
- Locate the water inlet valve, usually found at the bottom of the machine.
- Inspect it for any visible damage.
- If damaged, you may need to replace it. Consult your dishwasher’s manual for specific instructions.
Step 3: Correct Dish Loading
Incorrectly loaded dishes can also be a culprit. Make sure you’re not overcrowding the upper rack or blocking the spray arms.
- Refer to your dishwasher’s manual for proper loading instructions.
- Ensure that smaller items are not blocking the spray arms.
- Reorganize the dishes and run a test cycle.
Step 4: Clean the Filters
Dirty filters can reduce water flow, affecting the cleaning efficiency of the upper rack.
- Locate the filters at the bottom of your dishwasher.
- Remove and clean them with warm soapy water.
- Replace the filters and run a test cycle.
