Why Does My Dishwasher Drain All the Time?

If the dishwasher drains all the time or runs constantly, it may be in overflow protection. It will then be necessary to check and test the components which may be the cause of this failure. If it is a leak, it will therefore be necessary to know which side it is on.

It will therefore be necessary to check several points:

• overflow protection
• organs on the side
• the elements under the tank

If your dishwasher seems to be stuck in a constant draining cycle, it can be a perplexing and inconvenient problem. The dishwasher should only drain when necessary, such as at the end of a wash cycle. If it continues to drain continuously, there may be an underlying issue that needs attention. In this article, we will explore some common reasons why a dishwasher may drain all the time and provide guidance on how to address them.

1. Clogged or Blocked Drain Hose

A clogged or blocked drain hose can prevent proper water drainage and cause the dishwasher to continuously drain. Here’s what you can do:

1. Inspect the Drain Hose: Check the drain hose, which is usually located at the back of the dishwasher, for any kinks, twists, or obstructions. Ensure that it is properly connected and free from debris.
2. Clear the Drain Hose: If you notice any blockages in the drain hose, carefully remove them using a long brush or by flushing water through the hose. Take care not to damage or dislodge any connections.

2. Clogged Filter or Pump

A clogged filter or pump can impede water flow and cause the dishwasher to drain continuously. Consider the following steps:

1. Check the Filter: Locate the dishwasher’s filter, typically at the bottom of the dishwasher, and inspect it for any debris or buildup. Clean or replace the filter if necessary.
2. Examine the Pump: The dishwasher’s pump may also become clogged with food particles or other objects. Refer to the dishwasher’s manual to locate the pump and clear any obstructions if needed.

3. Faulty Float Switch or Water Inlet Valve

The float switch and water inlet valve work together to regulate the water level inside the dishwasher. If either of these components malfunctions, it can cause the dishwasher to continuously drain. Consider the following steps:

1. Check the Float Switch: The float switch is typically located at the bottom of the dishwasher, near the front. Ensure that it moves freely and is not stuck in the raised position. Clean the float switch if there is any debris or residue.
2. Inspect the Water Inlet Valve: The water inlet valve controls the water flow into the dishwasher. If it is faulty or stuck open, it can cause continuous draining. Consult your dishwasher’s manual or a professional technician to inspect and replace the water inlet valve if necessary.

4. Drain Pump Issues

A malfunctioning drain pump can also cause the dishwasher to continuously drain. Here’s what you can do:

1. Test the Drain Pump: Refer to the dishwasher’s manual for instructions on how to test the drain pump for proper functionality. If the drain pump is not working correctly, it may need to be replaced.
2. Consult a Professional: If you are unsure about testing or replacing the drain pump, it is advisable to seek the assistance of a professional technician. They will have the expertise to diagnose and repair the issue effectively.

5. Control Board Malfunction

A malfunctioning control board can cause various issues in a dishwasher, including continuous draining. If you suspect a control board problem, it is best to contact a professional technician for diagnosis and repair.

CHECK OVERFLOW PROTECTION

If your dishwasher is running all the time, it may be in overflow protection mode. Most dishwashers are equipped with a sheet under the tank to collect water in case of a leak.

In this case, the safety float is triggered, the drain pump runs continuously and the program is interrupted. Make sure the float is not damaged.

CHECK THE SIDES OF THE DISHWASHER.

To locate the leak, you will need to remove the top and sides of the dishwasher. This will allow you to check the tightness of the tank, water box and water pipes.

• After removing the top and sides of the unit, inspect both sides with a lamp for leaks.
• Run the program with remote parties, if necessary.
• Determine which element is defective and replace it.

OBSERVE THE ORGANS UNDER THE TANK

Now you will have to look under the device to identify the leak responsible for the presence of stagnant water. To do this, remove the receiving plate, it is usually screwed on at four ends. Also don’t forget to remove the float attached to it.

You will need to check if the following organs are damaged. If so, they will need to be changed:

• hoses and clamps
• drain pump
• circulation pump
• pressure switch
• flow meter
• changeover valve

In conclusion, a dishwasher that drains continuously can be caused by several factors, including a clogged or blocked drain hose, a clogged filter or pump, a faulty float switch or water inlet valve, drain pump issues, or a control board malfunction. By following the troubleshooting steps outlined in this article, you can identify and resolve many of these issues. However, if the problem persists or you are uncertain about performing any repairs yourself, it is best to consult a professional technician for further assistance. They will be able to diagnose the underlying cause of the continuous draining and provide the appropriate repair solution, ensuring your dishwasher operates as it should.
