Why Your Kenmore Dishwasher Isn’t Draining (and What You Can Do About It)
What To Know
- The drain hose is responsible for carrying wastewater from the dishwasher to the drainpipe.

- Common causes include a clogged drain hose, blocked filter, faulty drain pump, clogged air gap, faulty check valve, kinked drainpipe, or overloading the dishwasher.
A malfunctioning dishwasher can be a major inconvenience, especially when it refuses to drain. If your Kenmore dishwasher is giving you trouble, don’t despair. This comprehensive guide will explore the potential reasons behind this issue and provide practical solutions to help you get your dishwasher draining again.
Common Causes of Dishwasher Drainage Issues
1. Clogged Drain Hose
The drain hose is responsible for carrying wastewater from the dishwasher to the drainpipe. A blockage in the hose can prevent water from draining properly. Check for kinks, clogs, or crushing of the hose.
2. Blocked Dishwasher Filter
The dishwasher filter traps food particles and debris to prevent them from entering the drain hose. Over time, the filter can become clogged, restricting water flow. Clean the filter regularly according to the manufacturer’s instructions.
3. Faulty Drain Pump
The drain pump is the heart of the dishwasher’s drainage system. It pumps water out of the dishwasher and into the drain hose. If the pump is malfunctioning, it can prevent the dishwasher from draining.
4. Clogged Air Gap
The air gap is a small device that prevents wastewater from flowing back into the dishwasher. It can become clogged with food particles or debris, which can cause drainage problems. Clean the air gap regularly.
5. Faulty Check Valve
The check valve prevents water from flowing back into the dishwasher from the drainpipe. A faulty check valve can allow water to back up into the dishwasher, causing drainage issues.
6. Kinked or Crushed Drainpipe
The drainpipe is the final destination for wastewater from the dishwasher. If the drainpipe is kinked or crushed, it can restrict water flow and cause drainage problems.
7. Overloading the Dishwasher
Overloading the dishwasher can put excessive strain on the drainage system. This can lead to clogs and drainage issues. Always follow the manufacturer’s recommended loading capacity.
Troubleshooting and Solutions
1. Inspect and Clean the Drain Hose
Disconnect the drain hose from the dishwasher and inspect it for blockages. Remove any clogs or kinks and reconnect the hose securely.
2. Clean the Dishwasher Filter
Locate the dishwasher filter at the bottom of the dishwasher tub. Remove the filter and clean it thoroughly with warm water.
3. Test the Drain Pump
Disconnect the drain pump from the dishwasher. Connect a voltmeter to the pump’s terminals and turn on the dishwasher. If the pump is working, the voltmeter should read around 120 volts. If there is no voltage, the pump may be faulty and need replacing.
4. Clean the Air Gap
Locate the air gap on the countertop or under the sink. Unscrew the air gap and clean it thoroughly with warm water.
5. Replace the Check Valve
Turn off the water supply to the dishwasher. Disconnect the check valve from the drainpipe. Replace the check valve with a new one and reconnect the drainpipe.
6. Unclog the Drainpipe
If the drainpipe is kinked or crushed, carefully straighten it out. If the pipe is clogged, use a drain snake or plumber’s auger to clear the blockage.
7. Adjust the Dishwasher Load
Avoid overloading the dishwasher. Always follow the manufacturer’s recommended loading capacity to prevent drainage issues.
Prevention Tips
- Rinse dishes thoroughly before loading them into the dishwasher.
- Clean the dishwasher filter regularly.
- Avoid putting grease or oil down the drain.
- Run the dishwasher with a dishwasher cleaner monthly to prevent clogs.
- Have the dishwasher inspected and serviced by a qualified appliance technician annually.
