Whirlpool dishwasher Not Cleaning Top Rack

When your Whirlpool dishwasher is not cleaning the dishes in the top rack, do this: First clean the dishwasher filter. If this does not work, check the water supply line, remove some dishes, check the garbage disposer, and clean the dishwasher’s sprayer arms.

Don’t worry. I will expand on the above solutions in more detail below. However, before you proceed, here are some word of caution:

If your dishwasher is under warranty, the easiest solution would be to contact Whirlpool support and ask for advice. Unfortunately, opening your dishwasher will void its warranty in most cases, so leave it as a last option.

If this does not resolve the issue, try the additional fixes detailed below:

Check your Dishwasher Filter

On Whirlpool dishwashers, the filter is usually located at the bottom. If you are unsure how to access it, refer to your dishwasher’s manual.

Remove the filter, clean it with compressed air or water, and rerun the wash cycle on your Whirlpool dishwasher.

Check the Water Supply Line

There is also the possibility that the supply line has a blockage, preventing proper water supply to the dishwasher.

Remove it from your dishwasher and circulate pressurized water through it to remove any debris from it.

I’d also recommended to pour baking soda and vinegar solution through it and then passing hot water.

Remove some Dishes

If you put excessive dishes in your dishwasher, it won’t correctly clean. The reason is that each dishwasher has a maximum capacity beyond which it cannot clean the dishes.

Secondly, adding too many dishes can block the water sprayer from reaching other dishes.

I never recommend fully loading your dishwasher and leaving a quarter of room for better cleaning and optimal performance.

Check the Garbage Disposer

Ensure that the garbage disposer is properly installed on your Whirlpool dishwasher.

If you have just installed the garbage disposer, remember that the new disposer comes with a plug at the drain tube, which is to be removed before use.

Clean the Dishwasher Spray Arms

As its name suggests, the spray arms on the Whirlpool dishwasher are responsible for circulating and spraying the water on the dishes. They have small holes which does the spraying function.

If they are clogged, they won’t spray the water, thus leaving dishes in the top rack uncleaned.

Inspect the spray arm holes and see if they are clogged or not. You can clean them with a toothpick or small needle if they are clogged.


When your Whirlpool dishwasher leaves the dishes in the top rack uncleaned, try the following troubleshooting methods to fix it:

  • Check your dishwasher filter
  • Check the water supply/inlet line
  • Remove some dishes
  • Check the garbage disposer
  • Clean your dishwasher’s sprayer arms
  • Reset your Whirlpool dishwasher
