A malfunctioning dishwasher can be a major inconvenience, especially when it refuses to drain. If you’re facing this issue with your Frigidaire dishwasher, it’s crucial to understand the potential causes and find an effective solution. This comprehensive guide will delve into the reasons why your Frigidaire dishwasher won’t drain and provide step-by-step troubleshooting tips to restore its proper functioning.
Common Causes of Dishwasher Drainage Issues
1. Clogged Drain Hose
Over time, food particles, grease, and debris can accumulate in the drain hose, obstructing water flow. Check for any kinks or blockages in the hose and remove any obstructions.
2. Malfunctioning Drain Pump
The drain pump is responsible for pumping water out of the dishwasher. If it fails, water will remain in the dishwasher, preventing it from draining. Listen for unusual noises or vibrations coming from the pump during the drain cycle.
3. Faulty Check Valve
The check valve prevents water from flowing back into the dishwasher after it has been drained. A faulty check valve can allow water to accumulate in the dishwasher, leading to drainage issues.
4. Clogged Drain Impeller
The drain impeller is a rotating blade that helps to pump water out of the dishwasher. If it becomes clogged with debris, it can hinder the drainage process.
5. Blocked Air Gap
An air gap is a device installed above the kitchen sink to prevent contaminated water from flowing back into the dishwasher. If the air gap becomes blocked, it can create a vacuum that prevents water from draining.
6. Faulty Control Board
The control board is the brain of the dishwasher, controlling all its functions. If it malfunctions, it can disrupt the drainage cycle, leading to water accumulation.
7. Other Factors
Less common causes of drainage issues include a blocked garbage disposal, a kinked water supply line, or a faulty pressure switch.
Troubleshooting Steps
1. Inspect the Drain Hose
- Disconnect the drain hose from the dishwasher and check for any blockages.
- Use a flashlight to inspect the inside of the hose for any obstructions.

2. Test the Drain Pump
- Disconnect the drain pump from the dishwasher.
- Connect the drain pump to a power source and listen for it to operate.

3. Check the Check Valve
- Locate the check valve in the drain hose.
- Blow air through the check valve to see if it opens and closes properly.
- If the check valve does not open and close properly, it may need to be replaced.
4. Clean the Drain Impeller
- Remove the drain pump from the dishwasher.
- Locate the drain impeller and remove any debris that may be clogging it.
- Use a soft brush or a vacuum cleaner to clean the impeller thoroughly.
5. Inspect the Air Gap
- Locate the air gap above the kitchen sink.
- Remove the air gap and check for any blockages.
- Clean the air gap and reinstall it properly.
6. Reset the Control Board
- Unplug the dishwasher from the power outlet.
- Wait for 30 seconds.

- This will reset the control board and may resolve any software glitches that may be causing the drainage issue.
