Identifying and resolving these issues can effectively reinstate the dishwasher's ability to spray water.

Within this guide, each of these problems will be addressed, accompanied by recommended solutions. It's important to note that the solutions provided are geared towards do-it-yourself remedies. If you find yourself on a tight budget or unable to afford professional technician services at the moment, this guide offers practical steps to resolve the issue from the convenience of your home.

Why Is My KitchenAid Dishwasher Not Spraying Water?

1. Problem with the Float Switch

The float switch in a KitchenAid dishwasher serves the purpose of safeguarding against flooding during the dishwashing process. This switch operates by automatically shutting off once a sufficient amount of water has entered the dishwasher, preventing any further water from entering the unit.

In the event that the float switch becomes defective, your KitchenAid dishwasher may erroneously believe that it is already filled with water, causing it to shut down entirely.

To diagnose and address this issue, you can employ a digital multimeter electrical test kit with the reading set to 1 ohm. Use this kit to test the microchip associated with the float switch. If the test reveals a fault in the float switch, it should be replaced. Additionally, if you observe any signs of wear and tear on the float itself, it is advisable to replace the float as well.

2. Clogged Water Inlet Valve

The water inlet valve plays a crucial role in regulating the flow of water from its source into the dishwasher. This component operates by opening and closing periodically to ensure an appropriate amount of water enters the dishwasher.

Furthermore, it serves the essential function of closing to prevent excessive water from filling the dishwasher, thereby averting potential leaks that could lead to flooding the kitchen floor.

When the water inlet valve becomes obstructed, it prevents water from entering the dishwasher, resulting in the unit's inability to spray water during operation. This obstruction is typically caused by foreign objects and debris. Consequently, this issue can explain why you occasionally end up with dishes that are stained, emit unpleasant odours, or remain dirty even after a washing cycle.

In certain instances, the water inlet valve can become damaged either due to a short circuit or as a result of excessive use of the dishwasher.

To resolve this problem, follow these steps:

  1. Disconnect your dishwasher from both the power and water sources.
  2. Open the dishwasher and locate the water inlet valve.
  3. Thoroughly clean any obstructions or debris that may be present.

3. Clogged Chopper Blade

The chopper blade in your KitchenAid dishwasher serves a vital function by effectively reducing significant food particles into smaller pieces. This enables the dishwasher to easily expel these finer food remnants during each washing cycle.

Regrettably, the chopper blades can become dull, obstructed, or clogged when solid objects interfere with their operation. Over time, this hinders the appliance's ability to finely chop food particles, ultimately preventing the wash pump from spinning, thereby halting the dishwasher's entire operation.

When addressing this issue, exercise caution as you are dealing with sharp blades. Here are the steps to resolve the problem:

  1. Safely disconnect both the water and power supply to the dishwasher.
  2. Remove the access panel and anything obstructing your access to the chopper blade.
  3. Carefully clear any obstructions or clogs from the chopper blade.
  4. Attempt to manually rotate the blade to ensure it moves freely. Be cautious to avoid any contact with the sharp edges during this process.

If the chopper blade in your dishwasher is blunt, consider replacing it with a new one. Reinstall the part in the dishwasher, reconnect the water and power supply, and initiate a new wash cycle to verify if the issue has been resolved.

4. Clogged Spray Arms

Dishwashers, depending on their brand and model, can be equipped with one or more spray arms. These arms are perforated with holes that enable pressurized water to spray and effectively clean the dishes within the appliance.

These spray arms rotate to distribute water evenly over your dishes, but they may cease to function correctly if obstructed by food particles, dirt, or debris.

Food particles tend to obstruct the spray arms due to damaged filters, which can hinder the dishwasher's ability to remove debris from the circulating water inside the appliance.

Thankfully, resolving a clogged spray arm is a straightforward process:

  1. Utilize a Torx tool to unscrew the screws or bolts that secure the spray arm in place. Once removed, rinse the arm with water to dislodge the particles causing the blockage.
  2. Employ a soft-bristled brush to clear any dirt from each hole on the spray arm. You can also use a toothpick to unclog the holes or consider using a bottle brush for this purpose.
  3. Finish by giving the spray arm a thorough rinse with white vinegar.
  4. Reattach the spray arm to the dishwasher, reconnect the water supply and power, start a dishwasher cycle, and observe if the problem has been resolved.

5. Clogged Circulation Pump

The circulation pump in your KitchenAid dishwasher plays a crucial role in moving water throughout the appliance, facilitating the washing of dishes by directing water through components like the spray arm.

However, the pump can experience a malfunction if it becomes clogged, even when it's in good working condition. Similar to many other dishwasher parts, the circulation pump can get obstructed due to the presence of food scraps and other small debris carried by the circulating water within the unit.

The responsibility of the filter is to eliminate such contaminants from the system. Nevertheless, if the filter is soiled or damaged, it cannot perform its task effectively, leading to a clogged circulation pump. Consequently, certain components like the spray arm may be unable to spray water onto the dishes due to this blockage.

To resolve this issue, follow these steps:

  1. Remove the access panel, electrical connections, and hoses to gain access to the circulation pump.
  2. Take out the circulation pump and thoroughly clean any obstructions, including dirt, solid foreign objects, and debris.
  3. Clear away any dirt or debris that may be stuck on the impeller.
  4. Use your finger to manually spin the impeller, ensuring it rotates freely like a propeller.
  5. Reinstall the circulation pump, reconnect the water supply, and plug it back into the power source.
  6. Start the dishwasher and initiate a cycle to check if the dishwasher is now successfully spraying water.
