A Whirlpool dishwasher is one of the best brands for dishwashers. You can buy it. These machines have excellent warranties and high quality, but like any mechanical device, they can malfunction. Amongst the most common malfunctions for these dishwashers are ones in which the water does not spray out while in its cycle.

These machines have excellent warranties and high quality, but like any mechanical device, they can malfunction.

If your whirlpool dishwasher is not spraying water, then you are probably wondering what to do. This blog post will provide whirlpool dishwasher owners with a step-by-step guide on troubleshooting the problem and repairing their machine for it to work again.

Reasons Why Your Dishwasher Isn’t Spraying water

Here are some of the reasons why your Whirlpool dishwasher will not come on when triggered:
Mending water inlet valve issues

  • Improper Spraying
  • If your dishwasher is not spraying water, perform double-checks to ensure that the inlet water supply valve is accessible and open.
  • A dishwasher with too much detergent, sitting on a wet floor, or standing in water during the wash cycle can result in an appliance failure.
  • A dishwasher’s circulation pump is integral to the dishwashing process. If you have a faulty circulation pump, it may not adequately clean dishes after running in the cycle. The following steps can help identify and remedy a faulty circulation pump without having to call for professional assistance or take your unit apart.
  • If the dishwasher washes dishes but does not spray water, it can resolve this issue by removing and replacing the wash impeller.
  • Solution: Turn off power to the appliance before removing and replacing the wash impeller with a new one of the same size.
  • The dishwasher won’t spin and squirts with water.
  • Like most dishwasher brands, Whirlpool dishwashers come with several components that work together to keep them functioning correctly. When one part fails, it can throw the entire unit out of whack and result in various issues. This article will point you towards how to troubleshoot each issue by exploring common reasons for water spray.

Water Inlet Valve Issues

One reason dishes may not be getting clean is clogging in the valves that send water to the spray arms. The valve feeds hoses that distribute water to plumbing on both sides. Plumbing can become clogged with food particles and debris, blocking any water from entering the dishwasher.

Over time, continued blockages can cause the inlet valve to malfunction. If the inlet valve is clogged, it’s best to replace it and not try to clean it, as this can make it more susceptible to failure. New inlet valves for a Whirlpool dishwasher range from $20 – $60.

Spray Arm Issues

A clogged spray arm in your dishwasher can prevent water from spraying onto dishes, making them dirty. Food particles, grease, detergent, or mineral buildup usually block the small holes of the spray arms. To troubleshoot this problem, first, consult your owner’s manual to find a diagram and location for each component in your model dishwasher.

To determine if water is being sprayed adequately from your Whirlpool dishwasher, remove the racks and inspect its spray arms. Spin the arm to make sure there’s no restriction in movement.



To determine the problem, lay the spray arm on a hard surface and examine each hole. If the spray arm is clogged, you can use a fork or other object with small ends (such as a toothpick) to dislodge any debris or soak them in soapy water for ten minutes, then re-attach them to the dishwasher.

Water Supply Valve Issues

If your dishwasher doesn’t seem to be spraying water, there are two things you can do. The first is to check the inlet valve. In addition, it’s essential to ensure that water is getting from the shut-off valves and into the supply lines for acceptable use by your appliances.

You can check to see if a dishwasher leaks by locating the inlet hose under the sink or on the left side of the dishwasher. The inlet hose connects to a valve which should be turned on and not leaking.



If you find that it is leaking, there may need to call for maintenance assistance.

Overloaded Dishwasher

A whirlpool dishwasher not spraying water means the inlet hose is not connected correctly, or there’s a leak. Leaks can happen over time and need to be addressed by whirlpool maintenance assistance. Try to start the dishwasher again before removing any more dishes.

Clean dishes off both racks to make space for the spray arms to spin when it starts up again.

Circulation Pump Issues

One of the most pervasive issues with a dishwasher is its circulation pump. If this pump stops working due to clogs or everyday wear and tear, the motor will not continue to circulate any water out through the spray arms.
Whirlpool dishwashers typically fill with water and run the motor to pump out water during the rinse cycle. But if you turn on the dishwasher and there is no noise, it could be a problem with the power cord or burned-out motor.

To see if the pump is clogged:

  • Check under the dishwasher to ensure no debris is blocking it.
  • If so, remove the debris and put it in an appropriate bin.
  • Take off and test the water sprayer with a multimeter.

Wash Impeller Issues

All dishwashers have a central wash impeller to force water into the spray arms. The wash impeller, which can be damaged or lose fins from their everyday use, fails to create pressure that moves water into the spray arms.
The whirlpool dishwasher uses a diverter, which directs the water to the wash impeller. If you need only a repair kit for the pump or motor, you can also order the item individually.

When something goes wrong with the impeller, you can replace it with a new one. If the impellers are in good shape but just not creating enough pressure to operate correctly, you can buy most whirlpool dishwashers clean and dry for about $100-$200.

Faulty Water Pump Belt

Another possible reason for water not spraying out of your dishwasher may be because the pump belt has worn out. The water pump belt is an essential component that drives a high-pressure sprayer, and if it is old or needs replacing, you need to make sure this gets done before moving on with other troubleshooting steps. If you do have a belt, then it is replaceable.

One quick way to check if your water pump belt has worn out or not would be to pull the lower dish rack from inside of the machine and look at the bottom of those whirlpool dishes. If there are any gaps in between them, this could signify that something needs repairing.



How do you know when your dishwasher pump is no longer working?

A failed dishwasher pump can prevent a dishwasher from loading and draining water properly. When this happens, the spray arms on the dishwasher may also stop operating because there’s not enough water to reach them.

Ensure excess water drains from the dishwasher by pressing the “Cancel” button on your dishwasher control panel.

Listen for the motor of the pump to see if it’s running. If you hear a sound as soon as you press “cancel,” this means that the engine is working, but water isn’t draining through the unit. You may want to try a few things and the steps to fix the issue without calling in an expert or whirlpool dishwasher repair team. Some common whirlpool dishwasher problems associated with water flow include clogged sprayer heads (often caused by food debris) and dirty filters – which you might be able to clean yourself.

What is the cost of dishwasher pump replacement?

The cost of replacing your dishwasher’s water pump, depending on the brand and model, can range from $30 to $200. Installing the new part could take an hour or more, but it may only take a few minutes in some cases. Whether you’ve already called an appliance technician to inspect the problem or not, you mustn’t try to diagnose the dishwasher on your own.

Though a faulty pump can be detected and replaced relatively quickly, many other parts of the appliance could potentially require replacement should the dishwasher have an underlying issue.

How To Test A Circulation Pump On A Dishwasher?

To replace the circulation pump, locate the motor on your dishwasher. You can find it near the top of your appliance. Once you have discovered this, unscrew the bolts from around and remove the screws that hold down the motor cover. You should now see the whirlpool dishwasher not spraying the water pump by removing a few more pieces of plastic or metal.

To diagnose the problem, you will need a multimeter. If the voltage stays at 0 or near it, then the pump is good and does not require any repairs; if its reading shows up as high, you’ll want to repair it yourself before continuing with troubleshooting it.



What Is The Average Life Expectancy Of A Dishwasher?

Dishwashers typically last from five to ten years. But for those two years between when a new part is needed, only the defective part will replace an equally functioning one.
