Understanding the Dishwasher’s Drainage System
To effectively troubleshoot a non-draining dishwasher, it’s crucial to grasp the fundamentals of its drainage system. The drainage mechanism typically consists of:
- A drain hose that directs wastewater into the sink drainpipe
- A drain pump that generates the force to expel the water
- A check valve that prevents water from flowing back into the dishwasher
Common Causes of KitchenAid Dishwasher Draining Issues
When your KitchenAid dishwasher refuses to drain, the following factors may be responsible:
1. Clogged Drain Hose
Over time, food particles, grease, and debris can accumulate within the drain hose, creating a blockage.
2. Defective Drain Pump
The drain pump is the heart of the dishwasher’s drainage system. A faulty pump can hinder water expulsion.
3. Malfunctioning Check Valve
A faulty check valve allows water to flow back into the dishwasher, preventing proper drainage.
4. Blocked Air Gap
The air gap is a small device installed on the countertop to prevent contaminated water from flowing back into the dishwasher. A blocked air gap can impede drainage.
5. Clogged Garbage Disposal
If your dishwasher is connected to a garbage disposal, a blockage in the disposal can obstruct water flow.
6. Kinked Drain Hose
A kinked drain hose can restrict water flow and prevent proper drainage.
7. Faulty Control Board
The control board is the brain of the dishwasher. A malfunctioning control board can disrupt the drainage cycle.
Troubleshooting Steps
1. Inspect the Drain Hose
Disconnect the drain hose from the sink drainpipe and examine it for any kinks or blockages. Clear any obstructions and reconnect the hose securely.
2. Test the Drain Pump
Unplug the dishwasher and remove the lower access panel. Locate the drain pump and check for any debris or damage. Manually rotate the pump impeller to ensure it spins freely.
3. Check the Check Valve
Disconnect the check valve from the drain hose. Blow air through the valve to check for proper operation. If air flows only in one direction, the valve is functioning correctly.
4. Clean the Air Gap
Unscrew the air gap cover and remove any debris or blockages. Rinse the air gap thoroughly and reassemble it.
5. Unclog the Garbage Disposal
If your dishwasher is connected to a garbage disposal, run the disposal to clear any blockages. If the disposal is still clogged, call a plumber.
6. Straighten the Drain Hose
Ensure that the drain hose is not kinked or bent. Straighten any kinks to allow for unobstructed water flow.
7. Reset the Dishwasher
Unplug the dishwasher for a few minutes and then plug it back in. This may reset the control board and resolve the draining issue.
When to Call a Professional
If you have followed the troubleshooting steps outlined above but your KitchenAid dishwasher still does not drain, it may be time to seek professional assistance. A qualified appliance technician can diagnose and repair the underlying problem effectively.
