How to Tell if Washing Machine Drain Pump Is Bad?

To determine if a washing machine drain pump is bad, there are several symptoms to look out for.

Common indicators include water not draining from the drum, the machine stopping mid-cycle with water still inside, and improper spinning or draining.

Location And Function Of Washing Machine Drain Pump

The drain pump in a washing machine is essential for removing wastewater after a wash cycle. Typically located on the bottom right of the front of the machine, behind the accessible filter, it allows for easy access and maintenance. The drain pump is responsible for expelling used water from the drum, preventing it from stagnating and causing operational issues.

Common Symptoms Of A Faulty Drain Pump

To determine if the washing machine drain pump is bad, you can look out for these common symptoms:

  1. Failure to drain: If water fails to drain from the drum at the end of the washing cycle, your laundry will remain wet and may require manual removal of the water.

  2. Mid-cycle stoppage: If the machine stops in the middle of a cycle with water still inside, it is a clear indication of a malfunctioning drain pump.

  3. Improper spinning or draining: If you notice that the machine is not spinning or draining properly during the wash cycle, it is likely that there are issues with the drain pump.

It is important to address these symptoms promptly to avoid further damage to your washing machine.

Always consult a professional technician if you are unsure about how to diagnose or repair any issues related to your washing machine’s drain pump.

Causes Of Drain Pump Issues

Drain pump issues can arise due to a variety of reasons. One common cause is foreign objects getting caught in the pump or filter. Items such as coins, hairpins, and cloth fibers have the potential to clog the pump, obstructing its ability to function properly. Another cause of drain pump problems is a blocked filter or pump due to the accumulation of debris and detergent buildup. Over time, these residues can impede water flow and cause the pump to malfunction. Damaged impeller blades are another possible cause. The impeller, responsible for pushing water through the drain pump, can become worn or broken, resulting in improper drainage.

Steps To Clean And Inspect The Drain Pump

To address drain pump issues, it is recommended to thoroughly clean the filter and pump. Begin by removing any visible debris from the filter. Then, inspect the filter and pump for any signs of damage or blockages. Carefully remove any foreign objects that may be trapped. It is essential to check the impeller blades for any signs of wear, such as cracks or missing pieces. Clean the pump and filter using warm water and soap, ensuring all residues are thoroughly washed away. Once cleaned, reattach the filter and pump securely.

Troubleshooting Possible Blockages In The Drain Hose

If cleaning the filter and pump does not resolve the issue, it is essential to check the drain hose for blockages. A blocked hose can prevent the pump from operating correctly, leading to drainage problems. To troubleshoot this, detach the drain hose and inspect it for any obstructions. A simple visual inspection may reveal any significant blockages. If the blockage is severe, manual removal may be necessary. In some cases, the use of drain unblocker chemicals or a plumbing snake can help dislodge and clear the blockage. It is crucial to follow the manufacturer’s instructions carefully to avoid any damage.

Replacing The Bad Drain Pump: Steps And Recommendations

If all troubleshooting efforts indicate a faulty drain pump, it is necessary to replace it. The replacement process can vary depending on the washing machine model, but there are some general steps to follow.

First, lay the washing machine on its back or remove the cabinet to access the pump from the front. Disconnect the large hoses attached to the pump and remove any clips securing it. Take note of any parts that may need to be reused, such as the mounting bracket.

Depending on the brand and model, it may be recommended to use a screw-type hose clamp instead of a pinch-style clamp, especially for Whirlpool and similar models. Tutorial videos available on platforms such as YouTube can provide step-by-step guidance on how to replace the drain pump.

Finally, make sure to purchase a replacement drain pump that is compatible with your specific washing machine brand and model. These replacements are often readily available on websites like Amazon, making it convenient to find the appropriate part.
