Unclog your dishwasher and restore drain flow: the ultimate guide

A malfunctioning dishwasher can be a major inconvenience, especially when it refuses to drain properly. If you’re facing this issue, don’t despair. With the right knowledge and tools, you can diagnose and fix the problem yourself. This comprehensive guide will provide you with step-by-step instructions on how to troubleshoot and repair a dishwasher that doesn’t drain.

Check the Drain Hose

One of the most common causes of a dishwasher not draining is a kinked or clogged drain hose. Inspect the hose for any bends or blockages that may be preventing water from flowing through. If you find a kink, straighten it out. If the hose is clogged, you can try using a drain snake or a wet/dry vacuum to clear the obstruction.

Clean the Drain Filter

Another common culprit is a clogged drain filter. This filter is located at the bottom of the dishwasher and traps food particles and other debris. Over time, these particles can accumulate and prevent water from draining properly. To clean the drain filter, remove it from the dishwasher and rinse it thoroughly with hot water.

Check the Drain Pump

If the drain hose and filter are clear, the next step is to check the drain pump. The drain pump is responsible for pumping water out of the dishwasher. If the pump is faulty, it may not be able to drain the water properly. To test the drain pump, listen for a humming sound when the dishwasher is running. If you don’t hear a humming sound, the pump may be faulty and need to be replaced.

Check the Air Gap

The air gap is a small device located on the countertop or sink that allows air to enter the drain hose. This air helps to prevent water from siphoning back into the dishwasher. If the air gap is clogged, it can prevent the dishwasher from draining properly. To clean the air gap, remove the cap and rinse it with hot water.

Check the Float Switch

The float switch is a safety device that prevents the dishwasher from overflowing. If the float switch is faulty, it may not be able to detect the water level in the dishwasher and may cause the dishwasher to stop draining. To test the float switch, manually lift the float up and down. If the switch is faulty, it will not click when you move it.

Reset the Dishwasher

If you have checked all of the above components and the dishwasher still doesn’t drain, you can try resetting it. To reset the dishwasher, unplug it from the power outlet for at least 30 seconds. Then, plug it back in and start a new cycle.
