If your dishwasher seems to be perpetually attempting to drain, causing a relentless humming or gurgling sound, you’re not alone. This perplexing issue can be a source of frustration and inconvenience. Understanding the underlying causes is crucial for effective troubleshooting and resolving the problem.
Common Culprits Behind Constant Dishwasher Drainage
1. Clogged Drain Hose:
A kinked, clogged, or crushed drain hose can impede the smooth flow of wastewater. Inspect the hose for any obstructions and ensure it’s properly connected to the drainpipe.
2. Clogged Drain Pump:
The drain pump is responsible for expelling water from the dishwasher. If it becomes clogged with food particles, grease, or other debris, it may struggle to drain effectively.
3. Faulty Drain Switch:
The drain switch signals the dishwasher to start and stop draining. A malfunctioning switch can cause the dishwasher to drain continuously or fail to drain at all.
4. Overfilled Dishwasher:
Overloading the dishwasher with too many dishes can hinder proper water circulation and drainage. Ensure you’re loading your dishwasher correctly, leaving adequate space between items.
5. Leaking Float Switch:
The float switch detects the water level in the dishwasher. If it leaks or becomes stuck, it can send false signals, causing the dishwasher to drain excessively.
6. Malfunctioning Drain Solenoid:
The drain solenoid opens and closes the drain valve. A faulty solenoid can lead to continuous drainage or difficulty draining.
7. Damaged Control Board:
The control board manages the dishwasher’s functions, including drainage. A damaged control board can disrupt the drainage cycle, resulting in constant draining.
Troubleshooting and Resolution
1. Check for Drain Hose Obstructions:
Unplug the dishwasher and disconnect the drain hose. Inspect it for kinks, clogs, or damage. Remove any obstructions and reconnect the hose securely.
2. Clean the Drain Pump:
Locate the drain pump at the bottom of the dishwasher. Remove any visible debris from the pump and its housing. Use a small brush or toothpick to gently remove any blockages.
3. Test the Drain Switch:
Use a multimeter to test the drain switch for continuity. If there’s no continuity, replace the switch.
4. Reduce Dishwasher Load:
Avoid overloading your dishwasher. Load dishes loosely, ensuring proper water circulation and drainage.
5. Inspect the Float Switch:
Check the float switch for any signs of damage or leaks. Replace the switch if necessary.
6. Test the Drain Solenoid:
Use a multimeter to test the drain solenoid for resistance. If the resistance is too high or too low, replace the solenoid.
7. Reset the Control Board:
If all other troubleshooting steps fail, try resetting the control board. Unplug the dishwasher for 30 seconds and then plug it back in.

If you’re unable to resolve the issue with the troubleshooting steps outlined above, it’s advisable to contact a qualified appliance repair technician. They can diagnose the problem accurately and perform any necessary repairs or replacements.
