How To Fix Dishwasher Not Cleaning – Top Rack

If your dishwasher is not cleaning the top rack, then you need to read this article to the end because I will explain how you can solve this widespread problem, and your dishwasher will be able to work perfectly and effectively.

First, you must know why your dishwasher is not cleaning the top rack. 

Why Is My Dishwasher Not Cleaning The Top Rack?

Your dishwasher is not cleaning the top rack because there are several problems you need to identify so that you can solve them as soon as possible. 

These are common reasons why your dishwasher is not cleaning the top rack.

Upper Spray Arm is Obstructed

Immediately, when your dishwasher doesn’t clean the top rack, you need to check for obstructions. Very tall items in the bottom rack can block the spray arm from rotating.

The spray arm’s water will not reach the top rack dishes.

If you run the dishwasher with tall items, you need to ensure that the upper spray arm can spin freely. If it is blocked, you need to move the tall item.

Low Water Pressure

One of the common reasons why your dishwasher does not claim this property is because it has low water pressure.

Your dishwasher’s water should be distributed with high pressure between the bottom and upper racks. There won’t be enough for both racks if your water pressure is shallow. The dishwasher’s bottom rack will get clean, but the top will stay dirty.

Be careful of the activities that need water, like running the dishwasher while someone takes a shower or running your dishwasher when someone is taking a bath. This may be the cause of low water pressure.

If your dishwasher is not getting enough pressure, it may be due to a kink in the hose. The hose needs to run from the dishwasher to the fixture.

If you see a kink, unkink it by pulling it back and forth. It should help to return your normal pressure.

Low water pressure could be due to a clog in the bottom filter compartment, and it may be preventing water from getting into the circulation pump to provide you with the pressure you need.

Broken Spray Arm Seal

The seal on your dishwasher’s spray arm should prevent it from leaking, and if it breaks, you need to replace it immediately.

If your seal fails, water will leak out of the spray arm and away from the dishes in your top rack. 

Why Is My Dishwasher Not Cleaning My Cups?

These are common reasons your dishwasher is not cleaning your dish well, including your cups.

Broken Soap Dispenser

A broken Soap Dispenser may be one of the reasons why your dishwasher is not cleaning perfectly.

You need to check if your soap dispenser is not broken because the detergent target may not be able to reach your dishes or cups, or it may take a long time to reach your dishes, especially at the right time during the wash cycle.

It would be best to fix your dishwasher soap dispenser to solve the problem. 

Dirty Interior

Your dishwasher can never work perfectly and effectively if the interior is dirty. 

Many things are inside your dishwasher: grease, tiny food bits, mineral deposits from hard water, soap scum, and more.

So cleaning the interior of your dishwasher is very important, and it is an excellent first step when the dishwasher isn’t cleaning dishes.

Dirty Filter

Dirty filters can also cause the reason why you are dishwasher is not washing correctly and effectively.

Those old dishwashers, especially those made before 2010, are likely to have a self-cleaning filter that operates by grinding down foods and other particles until they are small enough to wash away.

You must clear your filter yourself if your dishwasher does not have a self-cleaning filter.
