Why Is My Washing Machine Pump Working But Not Draining? – The Ultimate Guide To Getting Your Washing Machine Working Again

A malfunctioning washing machine can be a frustrating experience, especially when its pump is running but the water refuses to drain. This peculiar issue can leave you wondering, “Why is my washing machine pump working but not draining?” In this comprehensive guide, we will delve into the potential causes behind this problem and provide practical solutions to restore your washing machine to its draining glory.

Clogged Drain Hose

The most common culprit behind a non-draining washing machine is a clogged drain hose. Over time, lint, hair, and other debris can accumulate in the hose, obstructing the flow of water.

Solution: Disconnect the drain hose from the washing machine and the drainpipe. Use a drain snake or a wire hanger to remove any visible clogs. Flush the hose with water to clear any remaining debris.

Faulty Drain Pump

The drain pump is responsible for pumping the water out of the washing machine. If the pump is malfunctioning, the water will not be able to drain properly.

Solution: Check if the drain pump is humming or making any unusual noises. If it is, it may be faulty and need to be replaced.

Blocked Drain Filter

Many washing machines have a drain filter that collects lint and other small objects. If the filter becomes blocked, it can prevent the water from draining.

Solution: Locate the drain filter, usually at the bottom of the washing machine, and remove it. Clean the filter thoroughly and replace it securely.

Kinked Drain Hose

A kinked or bent drain hose can restrict the flow of water.

Solution: Inspect the drain hose for any kinks or bends. Straighten the hose and ensure it is not crushed or obstructed.

Airlock in the Drain System

An airlock occurs when air gets trapped in the drain system, preventing the water from flowing out.

Solution: Fill a bucket with hot water and pour it down the drain. This can help break up the airlock and allow the water to drain.

Faulty Pressure Switch

The pressure switch detects the water level in the washing machine and signals the pump to start draining once the water has reached a certain level. If the pressure switch is faulty, it may not send the correct signal, resulting in the pump not draining the water.

Solution: Test the pressure switch using a multimeter. If it is faulty, it will need to be replaced.

Worn-Out Pump Belt

In some washing machines, the drain pump is driven by a belt. If the belt is worn or broken, it can prevent the pump from functioning properly.

Solution: Inspect the pump belt for any signs of wear or damage. If the belt is worn, replace it with a new one.

Final Thoughts: Reclaiming a Draining Washing Machine

By addressing the potential causes outlined above, you can effectively troubleshoot and resolve the issue of your washing machine pump working but not draining. Remember to exercise caution when working on electrical components and consult a professional if necessary. With a little patience and the right approach, you can restore your washing machine to its optimal draining performance, leaving you with clean clothes and a peace of mind.
