Common Causes of a KitchenAid Dishwasher Not Draining
Understanding the underlying issues is the first step to fixing the problem. Below are some of the most common reasons why your KitchenAid dishwasher might not be draining:
- Clogged Drain Hose: Debris or food particles can accumulate, blocking the flow of water.
- Blocked Garbage Disposal: If your dishwasher is connected to a garbage disposal, a clog in the disposal unit can affect drainage.
- Faulty Drain Pump: The pump responsible for pushing water out might be defective.
- Dirty Filter: A clogged filter prevents water from flowing out effectively.
- Air Gap Obstruction: An air gap blockage can hinder proper drainage.
Step-by-Step Guide to Fixing Your KitchenAid Dishwasher
Step 1: Turn Off the Power
Before working on your dishwasher, always turn off the power to ensure your safety. Unplug the unit or switch off the circuit breaker connected to it.
Step 2: Inspect and Clean the Filter
The filter is often the culprit when water pools at the bottom of the dishwasher.
- Locate the Filter: Usually found at the base of the dishwasher under the spray arm.
- Remove and Clean: Detach the filter and rinse it under warm water. Use a soft brush to scrub away debris and grease.
- Reinstall the Filter: Ensure it is securely placed to avoid future drainage issues.
Step 3: Check the Drain Hose
The drain hose connects the dishwasher to your home’s plumbing system. A clog here can impede water flow.
- Locate the Hose: Found at the back of the dishwasher.
- Inspect for Blockages: Disconnect the hose and look for any food particles or debris.
- Clean the Hose: Flush it with warm water or use a plumber’s snake to clear any blockages.
- Reconnect Securely: Ensure there are no kinks in the hose when reattaching it.
Step 4: Examine the Garbage Disposal
If your dishwasher shares a drain with the garbage disposal, ensure the disposal is clear.
- Check for Clogs: Remove any visible debris inside the disposal unit.
- Run the Disposal: Turn on the disposal to clear any small obstructions.
- Remove Knockout Plug (if newly installed): Ensure the plug in the disposal inlet is removed when setting up a new dishwasher.
Step 5: Inspect the Air Gap
The air gap prevents dirty water from backflowing into the dishwasher. It can sometimes become obstructed.
- Locate the Air Gap: Found near the sink, it’s a small cylindrical fixture.
- Clean the Gap: Unscrew the cap and remove any debris or buildup inside.
- Test for Blockages: Blow through the air gap tube to ensure it is clear.
Step 6: Test the Drain Pump
The drain pump is crucial for expelling water. If it’s faulty, it must be repaired or replaced.
- Access the Pump: Typically located at the bottom of the dishwasher.
- Check for Obstructions: Remove any food particles or foreign objects caught in the pump.
- Test the Pump Motor: Use a multimeter to check for electrical continuity. Replace the pump if it’s not functioning correctly.
Step 7: Inspect the Check Valve
The check valve prevents backflow into the dishwasher.
- Locate the Valve: Found along the drain line or at the base of the dishwasher.
- Inspect for Damage: Ensure it moves freely and is not stuck or damaged.
- Clean or Replace: If it’s clogged or faulty, clean or replace it as needed.
Step 8: Run a Diagnostic Cycle
Many KitchenAid dishwashers have a diagnostic mode that can identify errors.
- Consult the Manual: Refer to your dishwasher’s user manual for instructions on activating diagnostic mode.
- Run the Test: The cycle will pinpoint any issues that need attention.
- Address the Problem: Follow the error code guidelines provided by KitchenAid.
Step 9: Prevent Future Drainage Problems
Regular maintenance can keep your dishwasher functioning optimally.
- Rinse Dishes Before Loading: Avoid large food particles entering the system.
- Clean the Filter Weekly: A clean filter ensures smooth water flow.
- Inspect the Drain Hose Periodically: Prevent clogs by checking for debris or kinks.
