Uncover The Mystery: Why Is My Dishwasher Constantly Trying To Drain?

If your dishwasher is relentlessly attempting to drain, leaving you puzzled and frustrated, it’s time to delve into the underlying causes. This comprehensive guide will shed light on the potential culprits behind this persistent issue and provide practical solutions to restore your dishwasher to optimal performance.

Clogged Drain Hose

A clogged drain hose is a common cause of continuous draining. Food particles, grease, and other debris can accumulate in the hose, obstructing the flow of water. To resolve this issue:

• Disconnect the dishwasher from the water supply.
• Locate the drain hose and inspect it for kinks or blockages.
• Use a drain snake or a pair of pliers to clear any obstructions.

Faulty Drain Pump

The drain pump is responsible for pumping water out of the dishwasher. A faulty drain pump can lead to constant draining attempts. To test the drain pump:

• Listen for a humming noise when the dishwasher is draining.
• If there is no humming noise, the drain pump may be faulty.
• Contact a qualified appliance repair technician to replace the drain pump.

Malfunctioning Float Switch

The float switch detects the water level in the dishwasher. If the float switch malfunctions, it may send false signals to the control board, causing the dishwasher to drain continuously. To troubleshoot the float switch:

• Locate the float switch in the bottom of the dishwasher.
• Check if the float is stuck or damaged.
• If the float is faulty, replace it with a new one.

Blocked Air Gap

The air gap is a small device installed in the drain line that prevents backflow of water into the dishwasher. A blocked air gap can cause the dishwasher to drain constantly. To clean the air gap:

• Remove the air gap from the drain line.
• Clean the air gap with vinegar or a commercial cleaning solution.
• Reinstall the air gap and ensure it is securely connected.

Worn-Out Door Gasket

The door gasket seals the dishwasher door to prevent water from leaking out. A worn-out door gasket can allow water to escape, triggering the dishwasher to drain continuously. To inspect the door gasket:

• Open the dishwasher door and examine the gasket for tears or gaps.
• If the gasket is damaged, replace it with a new one.

Faulty Control Board

The control board is the brain of the dishwasher. A faulty control board can send incorrect signals to the dishwasher, causing it to drain constantly. To troubleshoot the control board:

• Reset the dishwasher by unplugging it from the power outlet for a few minutes.
• If the problem persists, contact a qualified appliance repair technician to diagnose and repair the control board.

Final Note

Understanding the underlying causes of why your dishwasher is constantly trying to drain is crucial for finding an effective solution. By following the troubleshooting steps outlined in this guide, you can identify and resolve the issue, restoring your dishwasher to its optimal functionality.
