The Whirlpool Company has been servicing homes for more than 100 years with home appliances like dishwashers. With their vast experience, the Whirlpool dishwasher has become a household favorite for its efficiency. However, some owners experience a problem with their washer not filling.

The most common reason why your Whirlpool dishwasher doesn’t fill with water is a broken inlet valve. If the valve is defective or clogged, your dishwasher will experience several issues, including overflowing and low water pressure. To solve this issue, replace the valve.

In this article, I explain what is causing your dishwasher to malfunction, and the steps needed to repair these problems at home. Let’s get started so you can go back to doing your dishes.

Whirlpool Dishwasher Doesn’t Fill With Water

If your Whirlpool dishwasher does not fill with water, your water inlet valve likely needs to be replaced. However, there are other reasons why your washer may not be producing water, including:

  • Clogged water supply
  • Blocked float area
  • Poorly placed drain hose

How To Fix a Clogged Water Supply

Over time, debris and calcium deposits build up around the water valve and can block your valve, stopping the water from moving. The debris can also cake up the water filter and stop the water from flowing.

To remove this debris and restore your dishwasher to normal functions:

  1. Turn off the water supply to the dishwasher.
  2. Locate the valve at the back of your machine.
  3. Remove the valve and inspect it for obstructions.
  4. Use a stick to remove large pieces.
  5. Clean the valve with a mix of baking powder and water. Alternatively, you can use warm water.
  6. Replace the valve and secure it in the dishwasher.

After doing this, ensure that the water supply valve is on, or the washer will not fill.

How To Remove a Blockage in the Float Area

The overfill protection float keeps the dishwasher from overflowing. When this part is out of place, the dishwasher will not fill. Usually, the float is in the front right corner of the dishwasher’s tub. You must first find the part and check for obstructions and if you notice any, remove them.

Next, you’ll need to adjust the float so that it is seated correctly in the dishwasher. Check if the float can move up and down freely, which will confirm that the float is in the right place.

Afterward, check to see if your dishwasher begins to fill. If this repair does not help, it is time to schedule a service.

How To Adjust a Poorly Placed Drain Hose

The drain hose releases the water after the wash cycle is completed. However, when the drain hose is too low, the water will begin siphoning. Therefore, if you’ve noticed that your brand new Whirlpool dishwasher is not filling, check your plumbing.

Ideally, a plumber should connect your drain hose to the disposal inlet and above other house plumbing. It is recommended that your hose is at least 20 in. (50 cm.) off of the ground.

Once your plumbing has been established, it isn’t easy to make adjustments unless you have experience. Therefore, if your pipe is too low, contact your local appliance store to find a specialist who can adjust it.

Whirlpool Dishwasher Doesn’t Spray Water

When your dishwasher doesn’t spray water, the spray arms need cleaning. To service your spray arms at home, you will need the following tools:

  • Wire or toothpick
  • Vinegar
  • Toothbrush

To remove the arms and clean them:

  1. Remove the bottom tray of your dishwasher.
  2. Locate the water filter and remove it.
  3. Detach the lower spray arm from the center of the dishwasher, which can be removed by hand.
  4. Scrub with the toothbrush to remove large debris.
  5. Use a wire or toothpick to remove any trash clogging the holes of the spray arm.
  6. Soak the spray arm in warm water and vinegar for at least ten minutes.
  7. Rinse the arm and position it in the dishwasher.
  8. Test that the spray arm moves freely.
  9. Repeat these steps on the upper spray arm.

These steps can remove tough grime from the spray holes in your arm and allow the water to flow freely. If you checked both spray arms and have determined that they are not dirty, consider measuring the water pressure in your home.

How To Know if My Water Pressure Is Too Low for My Whirlpool Dishwasher

Whirlpool dishwashers need at least 20 PSI to function. If your house’s supply is lower than that, your device will not spray or fill correctly. It will help if you test your water supply for issues. To begin, make sure there are no bends in the dishwasher’s hose. If there are kinks, manually straighten them out.

Next, you will have to check your home’s water pressure. Plug a pressure gauge into an outdoor hose and turn the hose to full blast. Afterward, observe the reading on your meter.

Generally, anything under 40 PSI is considered low water pressure. Still, if your reading is above 20 PSI, keep the shower and other utilities off while using the dishwasher, which can improve the water flow to your washer and encourage spraying.

However, for a pressure reading that is under twenty, consider contacting a maintenance specialist to boost your water supply.

Whirlpool Dishwasher Keeps Filling With Water

If you’ve noticed your dishwasher leaking when it’s off or continuously filling when it’s done washing, you have a broken or clogged water inlet valve.

Calcium deposits can build up and keep the valve open. If this happens, water will escape the valve despite the dishwasher being in the off position. Locate the valve and clean it if necessary.

Also, if your inlet valve has malfunctioned, it will keep filling with water, so you must replace the valve to stop the device from overflowing. This project requires the following tools:

  • Screwdriver
  • Plyers
  • Adjustable wrench

To change a faulty inlet valve:

  1. Turn off the power to the dishwasher.
  2. Shut down the water supply.
  3. Remove the four screws securing the toe kick panel at the front of the dishwasher.
  4. Unscrew the inner access panel and set it aside.
  5. Remove the two screws securing the water inlet bracket. The bracket is a silver knob with two screws on opposite ends.
  6. Detach the bracket. Lift from the rear of the metal part to remove it.
  7. Disconnect the two blue wires from their terminals. Pull the plastic tabs instead of the cables to prevent damage.
  8. Release the pinch clamp securing the hose with pliers.
  9. Pull off the hose.
  10. Use an adjustable wrench to unfasten the water supply line from the elbow fitting.
  11. Detach the inlet valve from the elbow fitting.
  12. Thread the fitting into the new valve and make sure it is secure.
  13. Reattach the water supply line to the fitting.
  14. Slide the clamp onto the outlet hose.
  15. Attach the hose to the water inlet valve port.
  16. Secure the hose with the pliers and fasten the clamp.
  17. Connect the wires to the inlet valve terminals.
  18. Replace the metal tab into its slot and mount the new inlet valve.
  19. Fasten the two screws.
  20. Position the inner access panel and toe kick panel and replace the screws.

Whirlpool Dishwasher Fills With Water But Won’t Start

If your Whirlpool dishwasher fills but does not start afterward, your washer may have the “Delay Wash” feature set. There are two ways to deactivate this setting:

  • Press “Cancel” to shut off the delay.
  • Press “Start” or “Resume” to continue the cycle.

If these steps fail, your washer needs to be cycled with a hard reset. Try resetting your dishwasher by unplugging it from its wall outlet for one minute. If your dishwasher connects to your breaker, you need to shut down the power supply temporarily. After you restore the power, your washer will start.

Whirlpool Dishwasher Not Heating Water

When your Whirlpool device stops heating the water, there is a broken heating assembly. Before attempting a repair, test the heating element with a multimeter to confirm that it has malfunctioned.

If it is broken, purchase a replacement from a certified supplier to ensure you get a high-quality piece.

To replace the heating element:

  1. Turn off the power supply.
  2. Shut off the water supply to your dishwasher.
  3. Use a screwdriver to release the lower access panels at the front of your dishwasher.
  4. Use a wrench to disconnect the water supply line.
  5. Remove the screws on the terminal block cover plate. Note the locations on the wires.
  6. Unfasten the screw securing the grounding wire.
  7. Use a flat head screwdriver to remove the strain-relief nut.
  8. Remove the wires from the junction box.
  9. Disconnect the drain hose.
  10. Remove the dishwasher from the wall and lie it flat on its back.
  11. Disconnect the wires to the heating element.
  12. Set the dishwasher upright.
  13. Detach the heating element from its position.
  14. Add the replacement.
  15. Return the dishwasher to its back.

  17. Stand the dishwasher upright.
  18. Replace the screw in the grounding wire.
  19. Secure the terminal block plate.
  20. Reconnect the water supply line.
