Why Is My Kenmore Dishwasher Not Draining? Here Are The Shocking Reasons!

If your Kenmore dishwasher is leaving your dishes soaked and unwashed, it’s time to investigate the culprit behind the drainage dilemma. Here’s a comprehensive guide to help you diagnose and resolve the issue, ensuring sparkling clean dishes once again.

The Clogged Drain Hose: A Common Suspect

The drain hose, responsible for carrying wastewater away from the dishwasher, is a prime candidate for blockages. Food particles, grease, and debris can accumulate over time, obstructing the flow of water. To check for a clogged drain hose:

1. Disconnect the drain hose from the sink or garbage disposal.
2. Inspect the hose for any kinks or bends.
3. Run water through the hose to check for flow. If water doesn‘t flow freely, the hose is likely clogged.

The Food Trap: A Hidden Culprit

The food trap, located at the bottom of the dishwasher, collects food particles and debris before they enter the drain hose. A clogged food trap can prevent water from draining properly. To clean the food trap:

1. Remove the lower dishrack.
2. Locate the food trap, usually at the center or back of the dishwasher floor.
3. Unscrew the food trap and remove it.
4. Clean the food trap and its filter with hot, soapy water.

The Drain Pump: The Heart of Drainage

The drain pump is responsible for pumping water out of the dishwasher. If the drain pump is faulty or clogged, water will not drain properly. To check the drain pump:

1. Disconnect the drain hose from the drain pump.
2. Use a flashlight to inspect the drain pump for any debris or blockages.
3. If you find any blockages, use a small brush or wire to remove them.

The Air Gap: A Vent for Drainage

The air gap is a small device installed on the countertop or sink to prevent water from siphoning back into the dishwasher. A clogged air gap can cause drainage problems. To check the air gap:

1. Locate the air gap on the countertop or sink.
2. Remove the cap and inspect the air gap for any blockages.
3. Clean the air gap and its filter with hot, soapy water.

The Check Valve: A One-Way Street for Drainage

The check valve is a small device installed in the drain hose to prevent water from flowing back into the dishwasher. A faulty or clogged check valve can cause drainage problems. To check the check valve:

1. Disconnect the drain hose from the drain pump.
2. Locate the check valve in the drain hose.
3. Blow air into the check valve. If air flows freely in both directions, the check valve is faulty.

The Pressure Switch: A Sensor for Drainage

The pressure switch is a sensor that detects the water level in the dishwasher. If the pressure switch is faulty, it may not signal the drain pump to start pumping water out. To check the pressure switch:

1. Disconnect the pressure switch from the dishwasher.
2. Use a multimeter to test the pressure switch.
3. If the pressure switch is faulty, replace it.

The Control Board: The Brain of the Dishwasher

The control board is the electronic brain of the dishwasher, controlling all its functions. If the control board is faulty, it may not send the correct signals to the drain pump or other components, causing drainage problems. To check the control board:

1. Disconnect the dishwasher from power.
2. Remove the control board from the dishwasher.
3. Inspect the control board for any burn marks or damage.
4. If the control board is damaged, replace it.

Wrapping Up: A Dishwasher That Drains Again

By following these steps, you should be able to diagnose and resolve the drainage issue in your Kenmore dishwasher. Remember to check for clogs, inspect components, and ensure proper connections. With a clear drain, your dishwasher will restore its ability to deliver sparkling clean dishes, making your kitchen chores a breeze.
