You’ve loaded your Whirlpool dishwasher with dirty dishes, turned it on, and expected sparkling clean results. But when you open the door, you find the dishes still wet, dirty, and worse, no water seems to have sprayed inside at all. You’re left wondering why your dishwasher isn’t working like it should. This problem is more common than you think, and it’s super frustrating when your dishwasher stops spraying water. Don’t worry — I’m here to help you understand why this happens and how to fix it step-by-step.
Check the Dishwasher Door
One of the easiest things to check when your Whirlpool dishwasher isn’t spraying water is the door. It might seem too simple to be the problem, but if the dishwasher door isn’t fully closed or latched, the dishwasher won’t spray water or start correctly. The door has a safety switch that tells the machine if the door is closed. If this switch doesn’t get the right signal, the dishwasher will not run the spray arms, meaning no water sprays on your dishes.
First, make sure you close the dishwasher door fully. Sometimes dishes or racks stick out and keep the door from closing tightly. Look closely to see if anything is blocking the door seal. The rubber seal around the door helps water stay inside and also lets the door latch close firmly. If the seal is torn or dirty, it might stop the door from closing well.
If the door looks fine but the dishwasher still won’t spray water, check the latch itself. Over time, the latch can wear out or break. If you hear a click when closing the door, that’s a good sign the latch is working. But if the latch feels loose or won’t catch, it might need to be replaced. You can order a new latch from Whirlpool or a parts store, and replacing it is usually simple with a screwdriver.
Another thing to check is the door switch. This small part inside the door frame senses if the door is closed. If it’s broken or stuck, the dishwasher thinks the door is open and won’t spray water. You can test the switch with a multimeter if you have one, or simply replace it if you suspect it’s faulty.
Always make sure the dishwasher door is completely shut and latched before starting the cycle. This small step often fixes the issue of no water spraying inside your dishwasher.
Inspect the Spray Arms
The spray arms in your dishwasher are what push water around to clean your dishes. If your Whirlpool dishwasher isn’t spraying water, the spray arms might be clogged or stuck. These arms have tiny holes where water sprays out under pressure. Over time, bits of food, hard water deposits, or soap scum can clog these holes and stop water from flowing properly.
To check the spray arms, open the dishwasher and pull out the bottom and top racks to access the arms. The spray arms are usually plastic with many small holes around the edges. Remove them carefully by unscrewing or unclipping, depending on your model. Once removed, hold the spray arms under running water and look through each hole. Use a toothpick or small brush to clear out any clogs.
While you have the spray arms out, check if they spin freely. When water sprays inside, the arms should spin to spread water evenly. If they don’t move or are stuck, you might have food or debris caught in the arm’s center or the bearings. Clean the inside well, rinse with warm water, and try spinning them by hand.
If spray arms are cracked or broken, water won’t spray out correctly. In this case, you’ll need to replace the damaged arms with new ones designed for your Whirlpool dishwasher model.
Regular cleaning of spray arms helps keep your dishwasher spraying water correctly and your dishes sparkling clean. If you notice the spray arms are dirty or clogged, clean them right away.
Clean the Filter
A dirty or clogged filter is a common reason why your Whirlpool dishwasher doesn’t spray water well. The filter sits at the bottom of the dishwasher and catches food particles and debris. If it gets blocked, water flow slows down or stops, so the spray arms don’t get enough water pressure to spray dishes clean.
To clean the filter, first, remove the bottom rack of your dishwasher. You’ll see a round or rectangular filter near the base. Twist or lift it out carefully. Rinse the filter under running water and use a soft brush or sponge to scrub away stuck food, grease, or buildup. Avoid using harsh brushes that might damage the filter.
Make sure to clean both the fine mesh and coarse parts of the filter. A clogged filter can cause water to back up or stop flowing inside your dishwasher. Once clean, place the filter back securely. If it’s loose, small food particles can get past it and cause further blockages.
If your filter looks torn or damaged, replace it. A broken filter will not trap debris properly and can cause problems with water spraying.
Clean your dishwasher filter regularly—at least once a month if you use the dishwasher often. A clean filter keeps water flowing well and helps your dishwasher spray water properly on your dishes.
Check the Water Supply
Your dishwasher needs a good water supply to spray water inside. If the water supply is off or blocked, the dishwasher won’t fill or spray water at all. One of the first things to check if your Whirlpool dishwasher isn’t spraying water is the water supply valve.
The water supply valve is usually located under your kitchen sink or near the dishwasher. It looks like a small lever or knob connected to the water line going into the dishwasher. Make sure this valve is fully open so water can flow freely.
If the valve is closed or partly closed, not enough water will reach the dishwasher. Sometimes during plumbing work or cleaning, the valve might get accidentally turned off.
Check the water line itself for kinks or bends. A bent or pinched hose can block water flow. If you notice any damage to the hose, replace it with a new one.
Sometimes, mineral buildup inside the valve or water line can slow water flow. If you suspect this, you may need to call a plumber to clean or replace the parts.
If you turn on the dishwasher and don’t hear water filling, this is a good sign the water supply has an issue.
Make sure your home’s main water supply is on and has normal pressure too. Low water pressure can cause the dishwasher to not spray water properly.
Examine the Water Inlet Valve
The water inlet valve controls water entering your Whirlpool dishwasher. It opens when the dishwasher needs water and closes when it’s full. If this valve is broken or clogged, your dishwasher won’t fill with water, so the spray arms won’t spray anything.
The inlet valve is usually near the bottom of the dishwasher, where the water supply line connects. You might need to pull the dishwasher out from under the counter to see it.
If you suspect the inlet valve is the problem, unplug the dishwasher and turn off the water supply before checking. Inspect the valve for any obvious damage or leaks.
A common issue is that the valve’s filter screen gets clogged with dirt or minerals. You can clean this screen gently with a brush. But if the valve itself is broken or stuck, you’ll need to replace it.
To test if the valve is working, you can use a multimeter to check for electrical continuity. If the valve doesn’t get power or fails this test, it should be replaced.
Replacing the water inlet valve isn’t too hard, but if you’re unsure, ask a professional for help to avoid leaks or damage.
Test the Float Switch
The float switch is a small safety device inside your dishwasher that tells it when it has enough water. It looks like a little plastic dome or cylinder that floats on the dishwasher floor. When the water rises, the float lifts up and signals the dishwasher to stop filling.
If the float switch is stuck or broken, your dishwasher may think it’s already full of water and won’t fill or spray water during the wash cycle.
To check the float switch, open the dishwasher and find the float inside at the bottom. Make sure it moves up and down freely. If it’s stuck in the “up” position, gently lift and lower it several times to free it.
If the float looks damaged or won’t move, it needs to be replaced.
You can also test the float switch with a multimeter for electrical continuity. If it doesn’t work properly, replacing it usually solves the no-spray water problem.
Keep the float and its housing clean of debris. Sometimes small food pieces or buildup can trap the float, stopping it from working.
Inspect the Pump and Motor
The pump and motor work together to push water through the spray arms inside your Whirlpool dishwasher. If either part is broken or clogged, water won’t spray inside.
The pump is usually located at the bottom of the dishwasher. It pulls water in and pushes it out with pressure.
If you hear strange noises during the wash cycle or no water spraying, the pump or motor might be the problem.
First, unplug your dishwasher and remove the lower access panel to get to the pump.
Check if the pump impeller (a small fan inside the pump) is blocked by debris like glass, food bits, or broken pieces from dishes. Remove any blockage carefully.
If the pump motor fails electrically, the pump won’t work. Testing the motor with a multimeter can help confirm if it’s bad.
Replacing the pump or motor can be more complicated, so if you aren’t comfortable, it’s best to call a repair technician.
A clean pump and motor mean your dishwasher will spray water properly and clean dishes well.
Look for Blockages in the Spray System
Sometimes, water pipes or hoses inside your Whirlpool dishwasher get blocked. These blockages stop water from flowing through the spray arms.
Check the dishwasher’s water supply hose, the spray arms, and the drain hoses for any bends, kinks, or clogs.
You can detach the hoses carefully and flush them with water to clear blockages.
Also, check the dishwasher’s internal water channels where water flows from the pump to the spray arms. Food buildup or mineral deposits can clog these parts.
Using a dishwasher cleaner regularly can help prevent buildup inside pipes and spray parts.
If you find hard water deposits or mineral buildup, soak parts in vinegar or a dishwasher cleaning solution to dissolve the deposits.
Removing blockages in the spray system is important because even if everything else works, blocked pipes stop water from reaching your dishes.

Frequently Asked Questions (FAQs)
Is it normal for the dishwasher door to feel hard to close sometimes?
Yes, it’s normal for dishwasher doors to feel a bit tight when closing because of the door seal, which keeps water inside. However, if the door is very hard to close or won’t latch, it might mean the seal is dirty, warped, or the latch is broken. Dirt or food stuck in the seal can stop the door from closing fully, which can prevent the dishwasher from spraying water. Cleaning the seal and checking the latch can fix this issue. If the door remains hard to close, replacing the seal or latch might be necessary.
Can clogged spray arms cause the dishwasher to stop spraying water?
Absolutely! Spray arms have tiny holes that water sprays out of to clean your dishes. When these holes get clogged with food, grease, or hard water deposits, water can’t spray out properly. This means the dishwasher won’t clean dishes well or might seem like it’s not spraying water at all. Cleaning spray arms regularly by removing and rinsing them can prevent clogging. Using a toothpick or brush to clear holes is an easy fix that keeps the spray arms working perfectly.
Do I need to clean the dishwasher filter often?
Yes, cleaning the dishwasher filter often is important for good dishwasher performance. The filter catches food bits and debris to stop them from clogging the pump or spray arms. If the filter gets dirty or clogged, water flow slows, and the dishwasher may not spray water well. It’s a good habit to clean the filter every few weeks or at least once a month. Simply remove the filter, rinse it under running water, and scrub it gently with a soft brush to keep it clear and clean.
Is it easy to check if the water supply valve is open?
Yes, checking the water supply valve is usually easy. This valve is often under the kitchen sink or near the dishwasher. It looks like a small lever or knob. If the valve is turned off or partly closed, water won’t flow into your dishwasher. Simply turn the lever to the fully open position to allow water in. If you don’t see water coming in during a cycle, checking this valve is one of the first steps to fix the problem.
Can a faulty water inlet valve stop water from spraying?
Yes, a faulty water inlet valve can stop water from entering the dishwasher, which means no water will spray inside. This valve opens to let water in when the dishwasher starts and closes when it has enough water. If it’s broken, stuck, or clogged, the dishwasher won’t fill with water. You might not hear water filling sounds during the cycle. Testing or replacing the inlet valve can solve this issue, but if you’re not sure how, a repair technician can help.
Do I need special tools to test the float switch?
No special tools are needed to test if the float switch moves freely. You can open the dishwasher and gently lift and lower the float to see if it moves without sticking. However, if you want to test the electrical part of the float switch, a multimeter is needed to check for continuity. Most people don’t have this tool, so if you think the float switch is broken, replacing it might be easier than testing it yourself.
Is the pump easy to clean and check?
Cleaning and checking the pump is a bit harder than other parts because it’s inside the dishwasher base. You need to unplug the dishwasher and remove the bottom panel to reach the pump. Then, you can check for debris blocking the pump impeller. If the pump motor is bad, testing with a multimeter is needed, which may require a professional. While cleaning small blockages is something you can do, electrical or mechanical pump problems usually need expert help.
Can blockages inside pipes cause water not to spray?
Yes, blockages inside the dishwasher’s water pipes or hoses can stop water from reaching the spray arms. Food debris, mineral deposits, or kinks in hoses can block water flow. Flushing hoses and soaking parts in vinegar can clear blockages. Regular cleaning with dishwasher cleaners also helps prevent buildup inside pipes. Fixing these blockages restores water flow and helps your dishwasher spray water properly.
