How to test your dishwasher’s drain pump and solve drain issues once and for all

A faulty drain pump can lead to a dishwasher that won’t drain properly, leaving dishes wet and potentially smelly. If you’re experiencing this issue with your GE dishwasher, it’s important to test the drain pump to determine if it’s the culprit. This blog post will provide you with a comprehensive guide on how to test a GE dishwasher drain pump and troubleshoot any potential problems.

How to Access the Drain Pump

1. Unplug the dishwasher from the power outlet.
2. Turn off the water supply to the dishwasher.
3. Open the dishwasher door and remove the lower dishrack.
4. Locate the drain pump at the bottom of the dishwasher tub. It is usually a cylindrical or square-shaped component with a motor and impeller.

Visual Inspection

Before testing the drain pump, it’s a good idea to perform a visual inspection. Check for any visible damage, such as cracks, leaks, or loose wires. If you notice any abnormalities, it’s best to replace the drain pump.

Electrical Testing

Step 1: Disconnect Wires

Disconnect the wires connected to the drain pump. Use a multimeter to test for continuity between the terminals on the pump.

Step 2: Check for Continuity

Set the multimeter to the ohms setting. Touch one probe to each terminal on the pump. If the multimeter reads “0” or a low resistance value, the pump is likely functional. If the multimeter reads “OL” (open line), the pump is faulty and needs to be replaced.

Step 3: Check for Ground Faults

Set the multimeter to the AC voltage setting. Touch one probe to the ground terminal on the pump and the other probe to each of the other terminals. If the multimeter reads any voltage, there is a ground fault and the pump needs to be replaced.

Mechanical Testing

Step 1: Remove Drain Impeller

Remove the drain impeller from the pump. Check for any obstructions or damage to the impeller blades. Clean or replace the impeller if necessary.

Step 2: Manually Turn Impeller

Try turning the impeller by hand. It should rotate freely without any resistance. If the impeller is stuck or difficult to turn, the pump is likely faulty and needs to be replaced.

Troubleshooting Common Drain Pump Issues

Noisy Drain Pump

A noisy drain pump could indicate a blockage or a worn-out bearing. Check the drain hose and impeller for any obstructions. If there are no blockages, the pump may need to be replaced.

Dishwasher Not Draining Completely

If your dishwasher is not draining completely, the drain pump may be clogged or faulty. Check the drain hose and impeller for any obstructions. If the pump is clogged, clean it thoroughly. If the pump is faulty, it will need to be replaced.

Dishwasher Leaking Water

A leaking dishwasher could be caused by a damaged drain pump seal or a faulty drain hose. Inspect the pump seal and drain hose for any leaks. If either component is damaged, it will need to be replaced.

The Bottom Line: Maintain an Efficient Dishwasher

By following these steps, you can effectively test a GE dishwasher drain pump and troubleshoot any potential issues. Remember to regularly maintain your dishwasher by cleaning the drain hose and impeller, and checking for any leaks. This will help ensure that your dishwasher continues to operate efficiently and effectively.
