Unclog your dishwasher circulation pump: a step-by-step guide to unblocking the bloodline of your machine

Your Whirlpool dishwasher’s circulation pump is a crucial component responsible for circulating water throughout the appliance during the wash cycle. If the pump malfunctions, it can disrupt the cleaning process and leave your dishes dirty. Testing the circulation pump is essential for troubleshooting and ensuring optimal dishwasher performance.

Identifying the Circulation Pump

Locate the circulation pump inside the dishwasher’s base. It’s usually situated at the bottom of the appliance, connected to the wash arm or spray arm. The pump typically has a black or gray plastic housing and electrical wires attached to it.

Step-by-Step Testing Procedure

1. Unplug the Dishwasher: Disconnect the dishwasher from the power source for safety.

2. Access the Pump: Remove the dishwasher’s lower access panel or kickplate to expose the circulation pump.

3. Disconnect the Wires: Use a screwdriver to carefully disconnect the electrical wires connected to the pump.

4. Remove the Pump: Unbolt the pump from the dishwasher’s base using a wrench or socket set.

5. Inspect the Pump: Examine the pump for any visible damage or debris. Clean any debris or blockages from the pump housing and impeller.

6. Test the Motor: Connect the pump to a 120-volt power source using jumper wires. If the pump motor runs smoothly, it indicates a healthy motor.

7. Check the Impeller: Rotate the impeller by hand. It should spin freely without any resistance. If the impeller is stuck or damaged, the pump may not be able to circulate water effectively.

8. Reinstall the Pump: If the pump passes the tests, reinstall it into the dishwasher. Reconnect the electrical wires and bolt the pump into place.

9. Plug in and Test: Plug the dishwasher back into the power source and run a test cycle. Observe if the wash arm or spray arm rotates smoothly, indicating proper water circulation.

Troubleshooting Common Issues

• No Water Circulation: If the wash arm or spray arm doesn’t rotate, the circulation pump may be faulty or there may be a blockage in the water supply line.
• Loud Noises: A faulty circulation pump can produce loud noises during operation. Replace the pump if necessary.
• Leaking: Leaks around the circulation pump can indicate a damaged pump seal or housing. Replace the pump or seal as needed.
• Overheating: If the circulation pump overheats, it may trip the dishwasher’s thermal fuse. Check the pump for any obstructions or damage.

Preventative Maintenance

To maintain the health of your Whirlpool dishwasher‘s circulation pump, follow these tips:

• Clean the dishwasher regularly to remove food particles and debris that can clog the pump.
• Use a dishwasher cleaner monthly to prevent scale buildup and blockages.
• Run the dishwasher on a hot water cycle occasionally to flush out any accumulated grease or detergent buildup.
