The drain pump of a washing machine makes it possible to evacuate the water present in the device at the end of the cycle. It is composed of a motor and a propeller to suck up the water.
It is probably at fault if you notice one of the following failures:
- The drain cycle does not start.
- The tub remains filled at the end of a programme.
- The pump does not make a draining noise.
Start by unplugging your washing machine to avoid any risk of electrocution.
The drain pump is located at the bottom of your device, on the left or right side. It can be identified by means of a trap door that simply needs to be opened to access the pump.
The drain pump in a washing machine is responsible for removing water from the machine during the drain cycle. If you notice that your washing machine is not draining properly or there is water remaining in the drum after a cycle, it may indicate a faulty drain pump. Testing and potentially replacing the drain pump can help restore proper drainage and ensure the optimal performance of your washing machine. In this guide, we will walk you through the steps to test and replace a washing machine drain pump.
Safety Precautions
Before starting any repair work on your washing machine, it is important to prioritize safety. Always unplug the machine from the power source before attempting any repairs. Additionally, ensure you are working in a well-lit area and wear protective gloves to prevent injury.
Tools Required
To test and replace a washing machine drain pump, you will need the following tools:
- Screwdriver set (Phillips or Torx, depending on your machine)
- Pliers
- Towels or rags (to protect the floor and clean up any spills)
Testing the Drain Pump
Follow these steps to test the drain pump in your washing machine:
Step 1: Unplug the Washing Machine
Ensure the washing machine is disconnected from the power source by unplugging it from the wall socket.
Step 2: Locate the Drain Pump
The drain pump is usually located at the bottom of the washing machine. Consult your washing machine’s user manual or search online for specific information about the location of the drain pump in your particular model.
Step 3: Access the Drain Pump
Remove any covers or panels that obstruct access to the drain pump. This may involve removing the back panel or a portion of the machine’s casing. Take caution and follow safety guidelines while removing components to prevent damage or injury.
Step 4: Inspect the Drain Pump
Visually inspect the drain pump for any signs of damage, blockages, or debris that may be obstructing its operation. Clear away any blockages or debris if present.
Step 5: Test the Drain Pump
With the washing machine still unplugged, locate the electrical connections on the drain pump. Using a multimeter, set it to measure resistance (ohms). Disconnect the electrical connections and touch the multimeter probes to the terminals on the drain pump. Consult your washing machine’s user manual or search online for the acceptable resistance range for the drain pump in your particular model. If the resistance reading is significantly different from the specified range or if it shows an open circuit, it indicates a faulty drain pump that needs to be replaced.
Changing the Drain Pump
Follow these steps to change the drain pump in your washing machine:
Step 1: Unplug the Washing Machine
Ensure the washing machine is disconnected from the power source by unplugging it from the wall socket.
Step 2: Access the Drain Pump
Remove any covers or panels that obstruct access to the drain pump, following the same steps as in the testing process.
Step 3: Disconnect the Electrical Connections
Carefully disconnect the wires connected to the drain pump. Take note of their positions or use a marker to label them for proper reconnection later.
Step 4: Remove the Faulty Drain Pump
Using a screwdriver, remove any screws or fasteners that secure the faulty drain pump in place. Carefully detach it from its mounting location.
Step 5: Install the New Drain Pump
Take the new drain pump and position it in place of the old one. Ensure it is aligned correctly and fits snugly. Insert and tighten the screws or fasteners to secure the new drain pump in place.
Step 6: Reconnect the Electrical Connections
Reconnect the wires to the new drain pump, ensuring they are properly positioned and securely attached. Refer to the labels or notes made during the disconnection process.
Step 7: Reassemble the Washing Machine
Once you have completed the drain pump replacement, reassemble any covers or panels you removed earlier to access the drain pump. Use the appropriate screws or fasteners to secure these components back in place.
Step 8: Test the Machine
Plug your washing machine back into the power source. Run a test cycle to ensure that the new drain pump is functioning properly. Observe the machine’s operation, ensuring that it drains water effectively without any issues.
If you encounter any persistent problems or suspect a fault with the drain pump despite the replacement, it is recommended to consult a professional appliance repair technician or contact the manufacturer for further assistance.
In conclusion, testing and replacing a washing machine drain pump can help restore proper drainage and ensure the optimal performance of your machine. By following these steps and using the appropriate tools, you can successfully diagnose a faulty drain pump and replace it to restore proper functionality. Always refer to your washing machine’s user manual for specific instructions and guidelines, as different models may have slight variations in the drain pump testing and replacement process. Regular maintenance and prompt drain pump replacement will help ensure the optimal performance of your washing machine.
