When you open your dishwasher after a cycle and find that there is standing water at the bottom, it can be quite alarming. After all, you expect your dishwasher to clean your dishes and remove all the water, leaving them sparkling and dry. So, is standing water in the dishwasher normal?
The answer is not a simple yes or no. While it is common for a small amount of water to remain in the dishwasher after a cycle, excessive standing water can be a sign of a problem. It is important to understand the reasons behind this issue and take appropriate action to prevent any further damage to your dishwasher.
One possible reason for standing water in the dishwasher is a clogged drain or filter. If the water cannot properly drain out, it will accumulate at the bottom of the machine. In this case, you can try cleaning the drain and filter to remove any debris or food particles that may be causing the blockage.
What Causes Standing Water in the Dishwasher?
Standing water in the dishwasher can be a frustrating problem that affects the cleanliness and functionality of your appliance. There are several potential causes for standing water in the dishwasher, including:
Clogged Drainage System: If the dishwasher’s drainage system is clogged with food particles or debris, it can prevent water from draining properly and cause standing water. It is important to regularly clean the dishwasher’s filter and check the drain hose for any obstructions. |

Clogged Drainage System
A common cause of standing water in the dishwasher is a clogged drainage system. Over time, food particles, soap scum, and other debris can accumulate and block the dishwasher’s drain. This restricts the flow of water and prevents it from draining properly, resulting in water pooling at the bottom of the dishwasher.
To check if the drainage system is clogged, start by removing the bottom rack and inspecting the drain area. Look for any visible blockages, such as food or debris, and remove them using gloves or a paper towel. If the blockage is harder to reach or deeper within the drain, a plumber’s snake or a similar tool may be required.
It is also worth checking the dishwasher’s drain hose for any kinks or obstructions. A bent or clogged hose can prevent water from properly draining out of the dishwasher. Straighten any kinks and remove any blockages if necessary.
In some cases, a clogged drainage system may require professional assistance. If you have tried the above steps and the standing water issue persists, it may be best to contact a licensed plumber or dishwasher repair technician. They will have the necessary tools and expertise to diagnose and fix the problem.
Preventing a clogged drainage system
To prevent a clogged drainage system in your dishwasher, it is important to practice proper maintenance. Here are some measures you can take:

Faulty Water Inlet Valve
If you notice standing water in your dishwasher, it could be due to a faulty water inlet valve. The water inlet valve is responsible for controlling the flow of water into the dishwasher. If it is not functioning properly, it may not be allowing enough water to enter the dishwasher, resulting in standing water.
A faulty water inlet valve can be caused by a number of factors. It may be clogged with debris, preventing it from opening fully and allowing water to flow freely. Alternatively, it may be worn out or damaged, preventing it from sealing properly and causing water to leak into the dishwasher.
To determine if the water inlet valve is faulty, you can perform a simple test. Start by disconnecting the dishwasher from the power supply and shutting off the water supply. Next, remove the water inlet valve from the dishwasher and inspect it for any signs of damage or clogs. If necessary, clean or replace the valve. Reinstall the valve and reconnect the dishwasher to the power and water supply.
Once the dishwasher is back in operation, check if the issue of standing water has been resolved. If not, it may be necessary to call a professional technician to inspect the dishwasher further and determine the underlying cause of the problem.
In conclusion, a faulty water inlet valve can lead to standing water in the dishwasher. By troubleshooting and repairing or replacing the valve if necessary, you can restore proper water flow and prevent this issue from occurring.
Improper Loading of Dishes
One common reason for standing water in the dishwasher is improper loading of dishes. If the dishes are not arranged properly, it can obstruct the water flow and prevent proper drainage. Here are some common mistakes that can lead to standing water:
- Overloading: Putting too many dishes in the dishwasher can obstruct the spray arms, preventing them from spraying water effectively.
- Blocking the spray arms: Placing large pots, pans, or other dishes in a way that blocks the spray arms can restrict their movement and prevent them from reaching all areas of the dishwasher.
- Improperly positioned utensils: If utensils are placed too close together or are sticking through the utensil basket, they can interfere with the spinning motion of the spray arms, leading to inadequate water coverage.
- Using the wrong dishwasher cycle: Some dishwasher cycles are designed for specific types of dishes or soil levels. If you’re using the wrong cycle, it might not provide enough water or time for proper cleaning and rinsing.
To avoid standing water due to improper loading, make sure to follow the dishwasher loading instructions provided by the manufacturer. Arrange dishes in a way that allows proper water circulation and ensure that nothing is blocking the spray arms.
Note: If you continue to experience standing water in the dishwasher after properly loading the dishes, it may be a sign of a larger issue, such as a clogged drain or a malfunctioning pump. In that case, it is recommended to seek professional help to diagnose and fix the problem.
Malfunctioning Float Switch
If you consistently find standing water in your dishwasher after each cycle, it could be due to a malfunctioning float switch. The float switch is a small device located at the base of the dishwasher, usually near the front. Its main function is to control the water level inside the dishwasher tub.
When the dishwasher is operating normally, the float switch rises as the tub fills with water. Once the water reaches a certain level, the switch is triggered to stop the flow of water and signal to the dishwasher that it is time to start the washing process. However, if the float switch is malfunctioning, it may fail to detect the correct water level and not signal the dishwasher to stop filling with water.
There are a few reasons why the float switch may not be working properly. It could be that the switch is stuck in the “up” position, which gives a false signal to the dishwasher that the water level is high enough. This could be caused by debris or food particles that have become trapped in the switch mechanism. Another possible issue is that the float switch has become disconnected or damaged, preventing it from functioning correctly.
If you suspect that the float switch is malfunctioning, it is recommended to contact a professional dishwasher repair technician to diagnose and fix the problem. They will be able to examine the switch and determine if it needs to be repaired or replaced. Attempting to fix the float switch yourself could lead to further damage or even injury.
In conclusion, a malfunctioning float switch can cause standing water in the dishwasher after each cycle. If you notice this issue, it is best to seek professional help to properly diagnose and address the problem. Ignoring the issue may lead to further damage to the dishwasher or potential flooding in your kitchen.
Damaged Dishwasher Pump
If you notice standing water in your dishwasher, it could be an indication of a damaged dishwasher pump. The pump is responsible for draining the water from the dishwasher after each cycle. If the pump is not functioning properly, it may not be able to remove all the water, leaving some standing in the bottom of the dishwasher.
There are a few common reasons why a dishwasher pump may become damaged. One possibility is that foreign objects, such as pieces of broken glass or small utensils, have become lodged in the pump. These objects can cause the pump to become clogged or damaged, preventing it from efficiently draining the water.
Another possible cause of a damaged dishwasher pump is wear and tear over time. The pump may simply become worn out and less efficient at draining the water. In some cases, the pump may need to be replaced entirely if it is beyond repair.
If you suspect that the dishwasher pump is damaged, it is best to contact a professional technician to diagnose and repair the issue. They will be able to assess the situation and determine if the pump needs to be replaced or if it can be repaired.
To prevent damage to the dishwasher pump, it is important to properly clean and maintain the dishwasher. This includes regularly checking for and removing any debris or foreign objects from the pump area. Additionally, it is recommended to avoid overloading the dishwasher, as this can put extra strain on the pump.
In conclusion, standing water in the dishwasher can be a sign of a damaged dishwasher pump. It is important to address this issue promptly to prevent further damage and ensure that your dishwasher functions properly.
Overuse of Dishwashing Detergent
Using too much dishwashing detergent can contribute to standing water in the dishwasher. It may seem counterintuitive, but using more detergent than recommended can actually result in a buildup of soap residue and a lack of rinsing. This can lead to water not draining properly, leaving behind a pool of water at the bottom of the dishwasher.
When too much detergent is used, the excess soap can create excessive suds and foam. These suds can prevent the dishwasher from effectively rinsing away the soap and can also interfere with the drainage process. As a result, the water may not be able to fully drain and can pool at the bottom of the dishwasher.
To prevent this issue, it is important to follow the manufacturer’s guidelines for detergent usage. Typically, dishwasher detergents are highly concentrated and require only a small amount to be effective. Using the recommended amount will ensure proper cleaning and rinsing, allowing the water to drain without any standing water remaining.
In addition to using the correct amount of detergent, it is also crucial to choose the right type of detergent for the dishwasher. Different dishwashers have different requirements, and using the wrong type of detergent may contribute to standing water. Consult the dishwasher’s user manual or the manufacturer’s website to determine the most suitable detergent for your specific dishwasher model.
Regular maintenance of the dishwasher can also help prevent standing water. Cleaning the dishwasher filters and checking for any clogs or blockages in the drain can ensure proper water flow and drainage. If standing water continues to be a problem, it may be necessary to contact a professional for further inspection and repair.
