How to fix Whirlpool Dishwasher not spraying water Problem?

Whirlpool Dishwasher not spraying water

There are different ways to fix the spraying issue on the dishwasher depending upon the issues.

First, you should figure out the issue, and then you can easily fix the spraying water problem on the dishwasher.

Therefore, here we will look at different problem and solution that causes the spraying water problem on your Whirlpool dishwasher.

Inlet valve Defect

A water inlet valve is part of the dishwasher that helps your dishwasher connect the water hose to the machine.

Besides this, the water inlet valve regulates water intake for both hot and cold water.

Similarly, when there is a problem with the dishwasher water inlet valve, you will see the problem with spraying arms. 

You will see different problems like slow water filing, higher or lower water temperature, or dishwasher stops working.

Similarly, you won’t hear any sound when your inlet valve is defective.

If you see any of these problems, you should consider changing the dishwasher inlet valve. 


The solution to a defective inlet valve is replacing the existing valve with a new valve.

The Inlet valve gets damaged when there is a short circuit or overuse.

To replace the inlet valve, you should have the proper tools and device to change from your dishwasher. Therefore, I suggest you call technicians to fix this issue.

Spray Arm problem

Sometimes the spray arms may be releasing water at a lower pressure which is very hard to notice.

In this case, there is a problem in your spray. The problem can be anything from damaged.

A broken or clogged spray arm is one of the major problems that you could see in Spray arms.

Therefore, it is suggested you make a proper inspection before concluding any problem. 

If you live in a place with hard water, there is a high chance of calcium or minerals building upon the dishwasher spray arms.

Besides this, sometimes, the food particles or debris can also clog spray arms.

If you have not cleaned your dishwasher for a while, consider cleaning your dishwasher spray arms with a soft brush. 


The solution to this problem is cleaning food particles and debris present on the dishwasher spray arms.

If you have not cleaned your dishwasher spray arms for a long time, then food and debris build could stop spray arms from working. So, I recommend you inspect the dishwasher spray arms. 

If the spray arms do not have food or debris clog, then make sure that there is no crack or faulty on the spray arms.

When the spray arms get cracked, it can cause water flow or leakage issues on the dishwasher.

If there are any cracks, then you should replace the spray arms. You can fix this issue temporarily by using duct tape on the broken parts.

Overloaded Dishwasher

Overloading is another problem that could cause a problem with the dishwasher spray arms.

Too many dishes during the cycle can create a load on the dishwasher, leaving dirty dishes on the dishwasher.

If your dishwasher is leaving dishes dirty, it doesn’t mean there is a problem with dishwasher spray arms. 

When you overload the dishwasher, it will block spray water to other dishes and leave dishes dirty.

Therefore, always load the dishes recommended by your manufacturer.

Overloading dishes can cause various issues on dishwashers like water leakage, dirty dishes, and damaged spray arms. 


There are three different types of racks on every dishwasher. You should always put the dishes according to dish racks.

In the first racks, it is recommended to keep cups, mugs, drinking glasses and plastic items. 

Similarly, in bottom racks, you should keep Trays, boards, and plates if there is space.

You can store lightweight utensils like a plate on middle racks. It is better to wash dishes in two cycles than to overload. So, avoid overloading of dishes on your dishwasher. 

Water valve defect

A defective water valve could stop water from getting into the dishwasher.

Spray arm gets affected in rare cases when the main water valve is damaged it cannot pass water through the spray arms.

The water inlet valve on the dishwasher fills water inside the dishwasher from the inlet hose. 

If you are not able to hear a water filling sound inside the dishwasher, then there is a problem with the water valve.

Similarly, if you can hear a water filling sound inside the dishwasher tanks, there is no problem with the water valve.

There should be another issue causing the spray arms problem on the dishwasher. 


If you think your dishwasher water inlet valve is defective or malfunctions, then you need to change that.

The water inlet valve is located just behind the dishwasher. You need to remove the dishwasher from the cabinet and open up a screw. Then you can access the inlet valve. 

But, I won’t recommend you remove and replace the dishwasher cabinet and panel.

You can increase the problem with the dishwasher. Therefore, it is suggested you call dishwasher technicians to fix the issue. 

Chopper blade clogged

The Whirlpool dishwasher has advanced features besides spray arms and drains pump.

There is also a chopper blade on the dishwasher, which helps the dishwasher cut food into smaller pieces.

This chopper blade cuts all the food particles into smaller pieces, making draining easy for the dishwasher.

Chopper blades are very sharp as they need to cut every food particle piece.

But, the problem arises when the chopper blade stop cutting food and stops spray arms from spraying water. When the blade gets jammed, the wash pump will stop spinning.


The problem can be fixed by cleaning food particles or debris, stopping the blade from rotating.

When it comes to cleaning debris, it is not as easy as it sounds. The chopper blade is located beneath the dishwasher, and the process can be daunting.

You need to remove the filter from the dishwasher; then, inside the pump inlet valve, you will find access to the chopper system. 

After this, you can easily see food particles and debris that could be stopping the chopper blade from rotating.

Clear all the food debris from the chopper, and then restart your dishwasher to see if the problem is fixed or not. If the problem is still not fixed, go to the next solution. 

Water supply issue

Sometimes users can unknowingly stop water coming from the pipe into the dishwasher.

When water can’t flow from the source, you cannot start the dishwasher.

So, makes sure that the water is properly coming from the tap to the dishwasher. If there is any blockage or calcium or mineral buildup, clean it up. 

Furthermore, it is necessary to use the dishwasher on recommended water pressure and temperature.

If there is low water pressure inside the dishwasher, water cannot pass through spray arms.

Similarly, high water pressure is also not good on the dishwasher. 


If you have changed the dishwasher water pressure and a temperature setting, forget to set the pressure on the recommended level.

See the user manual to know more about water pressure and temperature. Besides this, ensure that the water is properly from the tap to the dishwasher.

Float Switch Problem 

Float switch helps dishwasher from flooding. When too much water on dishwasher tanks, it turns off water from entering into the tank.

The float switch sends a signal to the dishwasher control panel, and then the control panel will instruct the switch from loading water into the dishwasher.

If the switch gets bad, it could send wrong information about water inside the tank and stop loading water inside dishwasher tanks.

When there is no water left on dishwasher tanks, spray arms will stop throwing water.

Sometimes the control panel chip can get damaged, which could misinform the float switch on loading water inside the dishwasher.


We discussed how a faulty switch could affect water loading onto the dishwasher tanks.

The solution to this problem is replacing the float switch with a new one.

But, before replacing, you need to make a proper inspection of the float switch and control board.

When the control panel starts to malfunction, it can misinform the float switch on loading water inside the dishwasher.

Therefore, I recommend you to make a proper inspection on both the float switch and control panel.

If you don’t have an idea about the float switch and control board I recommend you to call Whirlpool customer service or technicians.
