Why Pump Keeps Running
A washing machine drain pump that keeps running can waste energy and cause wear. Understanding why the pump keeps running helps fix the problem quickly. Several parts may cause this issue. Checking these parts can save time and money on repairs.
Faulty Water Level Switch
The water level switch tells the machine when to stop draining. If it fails, the pump may run nonstop. Dirt or damage can cause the switch to malfunction. Testing the switch with a multimeter shows if it works correctly. Replacing a faulty switch stops the pump from running continuously.
Blockages In Drain System
Blockages in the drain hose or filter can make the pump work harder. Water cannot drain properly. The pump keeps running to try to clear the blockage. Cleaning the drain hose and filter removes clogs. This helps the pump stop at the right time.
Stuck Drain Valve
The drain valve controls water flow out of the washer. If it gets stuck open, water keeps flowing. The pump runs nonstop to remove water. Dirt or wear can cause the valve to stick. Fixing or replacing the valve stops the pump from running too long.
Control Board Issues
The control board manages the washer’s functions, including the pump. A stuck relay or damaged circuit can keep the pump powered. Faulty control boards cause the pump to run without stopping. Inspecting and repairing the control board fixes this electrical problem.
Signs Of Drain Pump Problems
Recognizing signs of drain pump problems helps prevent bigger washer issues. Early detection saves time and repair costs. Watch your washing machine closely for these common symptoms. They often indicate trouble with the drain pump.
Incomplete Wash Cycles
Clothes stay wet after the cycle ends. Water remains in the drum or tub. The washer may stop mid-cycle without finishing. These signs suggest the pump cannot drain water properly.
Unusual Noises
Loud humming, buzzing, or grinding sounds come from the washer. Noises happen during draining or spinning. These sounds point to a stuck or damaged drain pump motor or debris caught inside.
Persistent Drain Sounds
The drain pump runs continuously after the cycle ends. You hear water pumping sounds even when the washer is off. This problem usually means the pump is stuck or the control board is faulty.
Bad Odors From Washer
A foul smell comes from inside the washing machine. Rotten or musty odors are common. These smells occur when water and debris stay trapped due to poor drainage. The drain pump may not be working properly.
Basic Troubleshooting Steps
A washing machine drain pump that keeps running can waste electricity and cause damage. Basic troubleshooting helps find the issue quickly. Follow simple steps to check common problems before calling a repair expert.
Start by ensuring the washer is safe to work on. Then, inspect parts that often cause pump issues. Clean any dirt or blockages that stop the pump from working properly. Check key components that control the pump’s function. These steps can fix many common problems.
Unplugging The Washer Safely
Always unplug the washing machine before starting any work. This prevents electric shock and injury. Find the power cord at the back or side of the washer. Pull the plug gently from the outlet. Do not touch the plug with wet hands. Wait a few minutes before opening the washer to avoid any residual electricity.
Inspecting Drain Hose
Look at the drain hose connected to the washer. Check if it is bent or clogged. A blocked hose stops water from draining. Remove the hose from the back of the machine. Use a long brush or water to clean inside the hose. Make sure it is free of any dirt or debris. Reattach the hose firmly to prevent leaks.
Cleaning Pump Filter
Find the pump filter, usually at the bottom front of the washer. Place a towel and bowl under it to catch water. Open the filter cover slowly. Remove the filter and clear out any lint, coins, or small objects. Rinse the filter under running water. Put the filter back and close the cover tightly. This helps the pump work without blockages.
Checking Float And Pressure Switch
The float and pressure switch control water level and pump operation. Open the washer’s top or back panel to find these parts. Check the float for dirt or stuck position. Clean it carefully with a cloth. Test the pressure switch hose for cracks or blockages. Replace any damaged parts to ensure the pump stops at the right time.

Fixing Blockages
Blockages often cause a washing machine drain pump to keep running. Dirt, lint, and small items can clog the drainage parts. Clearing these blockages helps the pump stop running and the machine to work properly. Simple steps can remove these obstructions and restore normal function.
Removing Hose Kinks
Start by checking the drain hose for bends or kinks. A twisted hose blocks water flow and forces the pump to run continuously. Straighten the hose carefully to allow smooth drainage. Make sure it is not crushed behind the machine or under heavy objects.
Clearing Pump Filter Debris
Locate the pump filter, usually at the front bottom of the washer. Open the filter cover and remove any trapped lint, coins, or debris. Clean the filter with warm water and a soft brush. A clean filter prevents water backup that makes the pump work nonstop.
Flushing Pressure Hose
The pressure hose links the water level switch to the tub. Dirt inside this hose can give false signals, causing the pump to run. Detach the hose gently and flush it with water to clear blockages. Reattach securely to ensure accurate water level readings and proper pump control.
Testing And Replacing Parts
Testing and replacing parts is key to fixing a washing machine drain pump that keeps running. Each part plays a role in controlling the pump’s operation. Faulty components can cause the pump to run nonstop.
Proper testing helps identify which part is defective. Replacing bad parts restores normal function. Below are common parts to test and replace for this issue.
Testing Float Switch With Multimeter
The float switch detects water level inside the washer. It signals the pump to turn on or off. Use a multimeter to test the float switch’s continuity.
Lift the float and check if the multimeter shows a closed circuit. No change means the switch is stuck or broken. Clean the float area or replace the switch if needed.
Replacing Faulty Pressure Switch
The pressure switch senses water pressure to control pump cycles. A faulty switch may send false signals, keeping the pump running. Remove the switch from the washer.
Check for visible damage or corrosion. Replace the switch with a compatible part. This stops the pump from running endlessly due to wrong pressure readings.
Fixing Or Replacing Stuck Drain Valve
A stuck drain valve can block water flow and confuse the pump’s control. Inspect the valve for debris or damage. Clean away dirt or mineral buildup carefully.
If the valve remains stuck, replace it. A smooth working valve allows proper draining and pump control. This can solve the problem of continuous pump running.
Diagnosing Control Board Relay
The control board relay manages power to the drain pump. A stuck relay may keep the pump powered without stopping. Inspect the relay on the control board.
Look for signs of burning or damage. Use a multimeter to test relay function. Replace the relay or control board if the relay is faulty. This restores proper pump control and stops constant running.

Preventive Maintenance Tips
Preventive maintenance helps keep your washing machine running smoothly. It stops the drain pump from running non-stop. Simple care can save you time and money. Regular checks catch small problems early. This section offers easy steps to maintain your machine.
Regular Cleaning Schedule
Clean the drain pump filter every month. Remove lint, hair, and dirt that block the pump. Wipe around the pump area to prevent buildup. A clean pump works better and lasts longer. Follow your machine’s manual for safe cleaning steps.
Avoiding Drain Blockages
Do not put large objects or thick fabrics in the washer. Use a mesh bag for small items like socks. Check pockets for coins, keys, and debris before washing. Clear the drain hose regularly to avoid clogs. Blockages cause the pump to run continuously.
Inspecting Hoses Periodically
Look at the drain and water hoses every few months. Check for cracks, bends, or leaks. Replace damaged hoses quickly to prevent water flow issues. Secure hose connections tightly to stop leaks. Proper hose care keeps the drain pump working well.
When To Call A Professional
Call an expert if the drain pump still runs after cleaning. Problems with the control board or pressure switch may need repair. Unusual noises or leaks also require professional help. Early service prevents costly damage and machine failure.
