Dishwasher Benefits and Drawbacks: What You Need to Know

If your dishwasher isn't distributing water, it's often due to issues with the circulation pump, spray arms, chopper blades, or the water inlet valve. Usually, a lack of water spray or pressure indicates that these components may have become obstructed or malfunctioned.

Reasons Why Dishwasher Won't Spray Water

Circulation Pump Failure

Description

Dishwashers rely on multiple pumps to operate effectively, with one of them being the circulation pump. This pump plays a critical role in recirculating water within the dishwasher, particularly by pushing it through components like the machine's spray arm.

When functioning correctly, the pump ensures that water is sprayed at the appropriate pressure to thoroughly clean items loaded into the dishwasher.

Causes of Failure

The circulation pump is susceptible to failure, especially after extended use. When this occurs, it initiates a cascade of issues. Firstly, water cannot circulate within the machine as it should, and any dishwasher detergent used may struggle to dissolve, leading to further blockages in components like the spray arm.

While this problem is increasingly common in newer Whirlpool and Maytag models, it's a universal issue that can affect almost any dishwasher brand and model over time.

Repair Procedure

Replacing a malfunctioning circulation pump is necessary. To do so, you'll need to access the inner workings of the dishwasher where the circulation pump is located.

Since dishwasher layouts can vary between brands, consulting the user manual or technical sheet is crucial to locate and identify the pump. Before starting the repair, remember to disconnect the dishwasher from its power and water sources.

This repair can be quite challenging, so don't hesitate to contact a qualified technician if needed. The process begins with removing the appropriate access panels and potentially disconnecting some hoses to reach the circulation pump.

Once you've accessed the pump, disconnect its electrical connectors and mounts, then install the new circulation pump in the same manner as the old one.

Differences Between Dishwashers and Refrigerators

Dishwasher

Dishwashers typically use more electricity and water during each cycle compared to refrigerators. However, they are used less frequently throughout the day.

Refrigerator

Refrigerators run continuously to maintain a low temperature, making them one of the most energy-consuming appliances in a household.

Alternative to Dishwasher

Dishwashing Basin or Tub

If you don't have a double sink, you can use a separate basin or tub for rinsing dishes. This conserves water and makes the process more efficient.

Circulation Pump Clogged

Description

As previously mentioned, the circulation pump plays a crucial role in recirculating water within the dishwasher. It accomplishes this by pumping water throughout the machine, including through the spray arm, to effectively clean the items placed inside the dishwasher.

Causes of Failure

Occasionally, a circulation pump can remain in good working condition but become clogged. Typically, these pumps become obstructed by small food particles and other debris that remain in the water as it circulates within the machine.

While some filters are designed to remove these items from the water supply, dirty or damaged filters may fail to perform this function, leading to foreign objects clogging the pump. Consequently, components like the spray arm may not be able to spray water with sufficient pressure to clean the dishes in the appliance.

Repair Procedure

Resolving this issue requires accessing the circulation pump. This involves removing access panels, hoses, and electrical connectors to allow the pump to be detached from its mounts and examined more closely. Once the circulation pump is removed from the machine, it becomes easier to remove any obstructions that are blocking it.

Clear away any dirt, debris, and especially any hard objects that may be stuck at the impeller. Before reinstalling the pump, ensure that you can freely rotate the impeller with your finger to verify its proper functioning.

Spray Arms Clogged

Description

Inside your dishwasher, you'll discover one or more spray arms, which are elongated plastic components featuring perforations that allow pressurized water to spray out and cleanse the dishes within the appliance. During this process, the spray arms rotate to ensure that all the contents inside the dishwasher receive an even spray.

Causes of Failure

The holes in the dishwasher's spray arms are relatively small, making them susceptible to clogging from smaller food particles, dirt, and debris. This issue is exacerbated when the appliance's filters are dirty or damaged, as they are unable to remove larger debris from the circulating water.

Repair Procedure

Fortunately, resolving a clogged spray arm is a straightforward process. Since the spray arms are situated in the dishwashing area and do not require the disassembly of access panels, they are easily accessible.

To address the issue, you will need to remove the bolt or screw that holds the spray arm in place. Once the clogged spray arm is removed from the machine, flush it with water to dislodge any items causing the blockage.

You can also use an old toothbrush to clear each of the small holes on the spray arm. Some individuals may prefer using other kitchen items, such as toothpicks or bottle brushes, for this purpose. It's essential to use whatever method effectively cleans the inside of each spray arm and eliminates any clogs.

Water Inlet Valve Clogged Or Burnt Out

Description

The water inlet valve plays a crucial role in regulating the flow of water from your home's water supply into the dishwasher. This valve opens and closes as necessary to ensure an adequate water supply while preventing over-filling and potential flooding of your kitchen floor.

Causes of Failure

If the water inlet valve becomes clogged with debris or foreign matter from your home water supply, it can disrupt the flow of water into the dishwasher. Additionally, the valve may become burnt out due to excessive use or a short circuit.

When this happens, the valve loses its ability to open and close properly, preventing water from entering the dishwasher. Even though the dishwasher may appear to be running, no water will spray because none has entered the appliance.

Repair Procedure

To access the water inlet valve, you typically need to open the top access panel on your dishwasher. The water inlet valve is the one directly connected to your home's water supply. After disconnecting the power and water supply, you can remove the valve for a closer inspection.

If the valve is clogged, you can remove any blockages and clean it thoroughly. If you detect burn marks or unusual smells, this is an indication that you should replace the valve entirely.

Replacing the valve is a relatively straightforward process: install the new valve in place of the faulty one and reconnect the electrical connector to the valve.

Conclusion

When your dishwasher won't spray water, it can be attributed to several potential issues, such as a malfunctioning circulation pump, clogged spray arms, or a faulty water inlet valve. Identifying and addressing the specific problem is essential to restore your dishwasher's functionality.

Whether it's cleaning out clogged components, replacing a malfunctioning part, or seeking professional assistance when needed, addressing the underlying causes of the issue can help ensure your dishwasher effectively cleans your dishes once again.

Regular maintenance and troubleshooting can go a long way in keeping your dishwasher running smoothly, ensuring it continues to provide the convenience and efficiency you rely on in your kitchen.
