Why Is My Dishwasher Only Draining? Here’s The Answer!

If your dishwasher is only draining and not completing its wash cycle, you’re not alone. This common issue can be frustrating and leave you with a sink full of dirty dishes. In this comprehensive guide, we’ll explore the potential causes and provide step-by-step solutions to get your dishwasher back in tip-top shape.

Common Causes of a Draining Dishwasher

• Clogged Drain Hose: Food particles, grease, and detergent buildup can accumulate in the drain hose, obstructing water flow.
• Faulty Drain Pump: The drain pump is responsible for pumping water out of the dishwasher. If it fails, the water will not drain properly.
• Blocked Air Gap: The air gap is a device installed above the sink that prevents dirty water from flowing back into the dishwasher. If it becomes clogged, it can impede drainage.
• Kinked Drain Line: A kink or bend in the drain line can restrict water flow and prevent proper drainage.
• Overloaded Dishwasher: Packing your dishwasher too tightly can block the spray arms and prevent water from reaching the dishes, resulting in poor drainage.
• Malfunctioning Door Latch: A faulty door latch can prevent the dishwasher from starting its wash cycle, including the drainage process.
• Electrical Issues: Electrical problems, such as a blown fuse or tripped circuit breaker, can disrupt the dishwasher’s functionality and hinder drainage.

Troubleshooting Tips

1. Check the Drain Hose

• Disconnect the drain hose from the dishwasher and sink.

• Clean any debris using a pipe cleaner or wire.

2. Test the Drain Pump

• Disconnect the drain pump from the dishwasher.
• Pour a cup of water into the pump.
• If the water drains out quickly, the pump is functioning correctly.

3. Inspect the Air Gap

• Locate the air gap above the sink.
• Remove the cover and check for clogs or debris.
• Clean the air gap with a sponge or brush.

4. Straighten the Drain Line

• Check the drain line for kinks or bends.
• Straighten any kinks or bends to ensure smooth water flow.

5. Reduce Dishwasher Load

• Avoid overloading your dishwasher.
• Load dishes in a way that allows water to reach all surfaces.

6. Check the Door Latch

• Open and close the dishwasher door several times.
• Listen for a clicking sound that indicates the latch is engaging.
• If the latch does not engage, it may need to be replaced.

7. Inspect Electrical Connections

• Check the fuse box or circuit breaker panel for blown fuses or tripped circuit breakers.
• Reset any tripped breakers or replace blown fuses.
