Dishwashers are essential household appliances that help us save time and effort by automating the task of cleaning dirty dishes. However, just like any other appliance, dishwashers can also experience faults or issues that can hinder their functionality. In this section, we will discuss some common faults in dishwashers and how to troubleshoot them.

1. Dishwasher Not Turning on

If your dishwasher is not turning on, the first thing to check is the power supply. Sometimes, the plug may have become loose, or there may be a tripped circuit breaker. If that’s not the case, then you should check if the door is closed properly. Many dishwashers have safety switches that prevent them from turning on if the door is not closed securely.

If the power supply and door are not the issue, then there may be a problem with the control panel or wiring of your dishwasher. In this case, it’s best to call a professional technician for repairs.

2. Dishwasher Not Filling with Water

A common fault in dishwashers is when they fail to fill with water. This can be caused by a clogged filter or inlet valve. The filter usually needs to be cleaned regularly, and the inlet valve may need to be replaced if it’s faulty.
Another reason for this issue could be a faulty float switch, which is responsible for regulating the water level in the dishwasher. If this is the case, then it’s best to call a technician for repair.

3. Dishes Not Getting Clean

If your dishes are not coming out clean after a wash cycle, there could be a few reasons behind this issue. The most common one is using the wrong detergent or too little of it. Make sure to use a dishwasher-specific detergent and follow the manufacturer’s instructions for the right amount to use.

Another reason could be a blocked spray arm or clogged filters. Make sure to clean these regularly to prevent any buildup of debris and food particles that can affect the dishwasher’s performance.

4. The Dishwasher Making Strange Noises

Unusual noises coming from your dishwasher can be alarming. However, they are often caused by minor issues that can be easily fixed. Most commonly, this could be due to loose or worn-out spray arms, which can be tightened or replaced.
If the noise persists, then it’s best to check for any foreign objects that may have fallen into the dishwasher and are causing a disruption in its functioning. It’s also recommended to clean the dishwasher regularly to prevent such issues.
In some cases, a malfunctioning motor or pump may be the cause of strange noises. This would require the expertise of a professional technician for repair.

5. Dishes aren’t being cleaned properly

When it comes to appliances like dishwashers, it’s essential to perform regular maintenance and upkeep to prevent any major faults or breakdowns. Make sure to read the manufacturer’s manual for specific instructions on how to clean and maintain your dishwasher. By following these guidelines and troubleshooting common issues, you can ensure that your dishwasher continues to function smoothly for a long time. So, it’s always better to keep an eye on your dishwasher and address any minor faults before they turn into major problems.


These are just a few common faults that can occur in dishwashers. It’s important to regularly clean and maintain your dishwasher to prevent these issues from arising. If you encounter any major problems, it’s always best to seek the help of a professional for proper repair and maintenance. With proper care, your dishwasher can continue to efficiently clean your dishes for years to come.
