Understanding the Dishwasher Pump
The pump is the heart of your dishwasher, responsible for circulating water and draining it away after the wash cycle. When the pump malfunctions, you might experience issues like:
- Slow draining: Water lingers in the tub after the cycle ends.
- No draining: The water doesn’t drain at all, leaving a stagnant mess.
- Loud noises: A grinding or humming sound from the dishwasher can indicate a failing pump.
Gathering Your Tools and Supplies
Before diving into the replacement process, gather the necessary tools and supplies. You’ll need:
- New Kenmore dishwasher pump: Make sure to order the correct pump model for your specific dishwasher.
- Screwdriver set: Phillips and flathead screwdrivers will come in handy.
- Adjustable wrench: For loosening and tightening nuts.
- Pliers: For gripping and removing stubborn parts.
- Flashlight: To illuminate the work area.
- Gloves: Protect your hands from sharp edges and water.
- Shop towels: For cleaning up spills and wiping down parts.
Disconnecting Power and Water Supply
Safety first! Before starting any repairs, always disconnect the power supply to your dishwasher. Unplug the appliance from the wall outlet or turn off the circuit breaker. Next, shut off the water supply to the dishwasher by turning the valve located under the sink.
Accessing the Dishwasher Pump
The location of the pump varies depending on the model of your Kenmore dishwasher. However, it’s typically situated at the bottom of the appliance, near the drain hose.
1. Remove the lower access panel: Locate the panel covering the pump. It’s usually held in place by clips or screws.
2. Remove the drain hose: Disconnect the drain hose from the pump outlet.
3. Disconnect electrical connections: Carefully disconnect the electrical wires leading to the pump. Make note of the wire positions for reconnection.
Removing the Old Pump
1. Loosen the mounting screws: Locate the screws securing the pump to the dishwasher base. Use an adjustable wrench or socket to loosen them.
2. Remove the old pump: Once the screws are removed, carefully lift the old pump out of its housing.
Installing the New Pump
1. Position the new pump: Carefully align the new pump in its housing, ensuring it’s positioned correctly.
2. Secure the pump: Tighten the mounting screws to secure the new pump in place. Be careful not to overtighten the screws.
3. Reconnect electrical connections: Attach the electrical wires to the new pump, matching the wire colors and positions to the old pump.
4. Reconnect the drain hose: Connect the drain hose to the pump outlet, ensuring a tight seal.
Testing the New Pump
1. Turn on the water supply: Open the water valve under the sink.
2. Turn on the dishwasher: Plug the dishwasher back in and select a rinse cycle.
3. Observe the pump operation: Listen for the pump to operate and watch for water draining from the dishwasher.
If the pump is working correctly, you’ve successfully replaced it!
Final Steps and Troubleshooting
1. Reassemble the dishwasher: Replace the lower access panel and ensure all screws are secure.
2. Run a full cycle: Run a complete wash cycle to test the dishwasher’s functionality.
3. Troubleshooting: If the dishwasher still doesn’t drain or exhibits other problems, check for the following:
- Clogged drain hose: Inspect the drain hose for blockages.
- Faulty drain hose: A damaged or cracked drain hose can prevent proper drainage.
- Incorrect pump installation: Ensure the new pump is securely installed and the electrical connections are correct.
Beyond the Pump: Common Dishwasher Issues
While replacing the pump addresses drainage problems, it’s important to be aware of other common dishwasher issues and their solutions:
- Leaking dishwasher: Check for worn-out door seals, cracked hoses, or loose connections.
- Dishwasher not filling: Inspect the water inlet valve and the water supply line for blockages or damage.
- Dishwasher not heating: Examine the heating element and the thermostat for signs of failure.
