How to Fix a Washing Machine That Is Over- or Under-Dispensing Detergent

Having a washing machine that over- or under-dispenses detergent can lead to less effective cleaning or wasted detergent. Here’s a guide on how to fix a washing machine that is experiencing these issues.

Understanding Detergent Dispensing Issues

Over-dispensing detergent can cause excess suds, leading to poor rinsing and potential residue on clothes. On the other hand, under-dispensing detergent can result in clothes not being cleaned thoroughly. Identifying the cause of these issues is the first step to fixing them.

Check the Detergent Drawer

1. Clean the Detergent Drawer: Over time, detergent residue can build up in the drawer, causing it to malfunction. Remove the drawer and clean it thoroughly with warm water. Make sure there are no blockages in the compartments.
2. Ensure Proper Loading: If the drawer is not seated correctly, it can affect detergent dispensing. Ensure it is properly aligned and inserted.

Inspect the Detergent Dispenser

1. Check for Blockages: Detergent dispensers can become clogged with detergent residue or debris. Clean the dispenser and check for any obstructions that might affect the flow.
2. Verify the Settings: Make sure you are using the correct detergent for your washing machine. Some machines require specific types of detergent, such as HE (High Efficiency) detergent.

Examine the Water Supply

1. Check Water Pressure: Low water pressure can affect detergent dispensing. Ensure that the water supply valves are fully open and that there are no kinks or blockages in the hoses.
2. Inspect Water Inlet Valves: The water inlet valves control the flow of water into the detergent dispenser. If these valves are faulty, it can lead to incorrect detergent dispensing. Consider having a professional check and replace them if necessary.

Review the Washing Machine’s Detergent System

1. Inspect the Flowmeter: Some washing machines have a flowmeter that measures the amount of water and detergent being used. If the flowmeter is malfunctioning, it can cause incorrect detergent dispensing. Consult your washing machine’s manual to locate and test the flowmeter.
2. Check for Software Issues: Modern washing machines with digital controls might have software that controls detergent dispensing. Ensure that the machine’s software is up to date and reset the machine if needed.

Consult the User Manual

Refer to your washing machine’s user manual for specific instructions related to detergent dispensing. The manual will often provide troubleshooting tips and detailed diagrams for your specific model.

Call a Professional

If you’ve tried the above steps and your washing machine is still having issues with detergent dispensing, it may be time to call a professional technician. They can diagnose and repair more complex problems with the detergent system or internal components.

Fixing a washing machine that is over- or under-dispensing detergent requires a bit of investigation and maintenance. By following these steps, you can ensure your washing machine dispenses the right amount of detergent, leading to cleaner clothes and a more efficient washing process
