A malfunctioning dishwasher can quickly turn into a kitchen nightmare. One of the most common problems is a dishwasher that won’t drain properly, leaving you with a pool of soapy water and a lingering odor. If you’re facing this frustrating issue with your KitchenAid dishwasher, don’t despair! This comprehensive guide will walk you through the most likely culprits and provide step-by-step solutions to get your dishwasher draining like a champ again.
Understanding the Drainage System
Before diving into troubleshooting, it’s helpful to have a basic understanding of how a KitchenAid dishwasher drains. The process involves a series of components working in harmony:
- Drain Hose: This hose connects the dishwasher to the drain line, allowing the wastewater to flow out.
- Drain Pump: This electric pump pushes the water through the drain hose.
- Impeller: This rotating component within the pump creates suction, pulling the water from the dishwasher tub.
- Check Valve: This valve prevents wastewater from flowing back into the dishwasher.
Common Culprits Behind a Clogged Drain
A KitchenAid dishwasher that won’t drain usually points to a blockage somewhere in the drainage system. Here are the most common culprits:
- Clogged Drain Hose: The drain hose can become clogged with food debris, grease, or other obstructions.
- Blocked Drain Pump: The drain pump impeller can get jammed with food particles or other debris.
- Clogged Drain Line: The drain line itself can become clogged, especially if it’s shared with other appliances.
- Faulty Drain Pump: The drain pump might be malfunctioning, preventing it from creating suction to remove the water.
- Stuck Check Valve: The check valve might be stuck in the closed position, preventing water from flowing out.
Troubleshooting Steps for a KitchenAid Dishwasher Not Draining
Now that you understand the potential causes, let’s dive into the troubleshooting steps. Remember to unplug the dishwasher before starting any work.
1. Check the Drain Hose
- Locate the Drain Hose: It’s usually found connected to the dishwasher’s bottom, leading to the drain line.
- Inspect for Clogs: Carefully examine the hose for visible blockages.
- Remove the Hose: Disconnect the hose from the dishwasher and the drain line.
- Clean the Hose: Use a cleaning brush or a hose attachment to remove any debris.
- Flush the Hose: Run water through the hose to ensure it’s clear.
- Reconnect the Hose: Make sure the hose is securely connected to both the dishwasher and the drain line.
2. Check the Drain Pump
- Locate the Drain Pump: The pump is usually located at the bottom of the dishwasher, near the drain hose.
- Inspect the Impeller: Look for any visible debris blocking the impeller.
- Remove the Impeller: If necessary, remove the impeller and clean it with a brush or a small screwdriver.
- Check for Damage: Inspect the pump for any signs of damage, such as cracks or broken parts.
- Replace the Pump: If the pump is damaged, you’ll need to replace it with a new one.
3. Check the Drain Line
- Locate the Drain Line: The drain line is usually found under the sink or in the wall.
- Inspect for Clogs: Look for any visible blockages in the drain line.
- Use a Drain Snake: If there’s a clog, use a drain snake to try and dislodge it.
- Call a Plumber: If the clog is too stubborn or deep, you may need to call a plumber to clear the drain line.
4. Check the Check Valve
- Locate the Check Valve: The check valve is usually located near the drain pump.
- Inspect the Valve: Look for any signs of damage or obstruction.
- Clean the Valve: If the valve is dirty, use a brush or a small screwdriver to clean it.
- Replace the Valve: If the valve is damaged, you’ll need to replace it with a new one.
Beyond the Basics: Potential Electrical Issues
If you’ve checked the drainage system and found no blockages, the problem might lie with the electrical components.
- Faulty Drain Pump Motor: A malfunctioning drain pump motor might be preventing the pump from running.
- Broken Wiring: Damaged wiring can interrupt the flow of electricity to the drain pump.
- Control Board Malfunction: A faulty control board can prevent the drain pump from receiving the signal to activate.
When to Call a Professional
While many dishwasher drainage issues can be fixed with a bit of DIY, there are times when it’s best to call a professional:
- Complex Electrical Issues: If you suspect a problem with the drain pump motor, wiring, or control board, it’s best to leave the repairs to a qualified technician.
- Persistent Clogs: If you’ve tried everything and the drain line is still clogged, a plumber can use specialized tools to clear the obstruction.
- Safety Concerns: If you’re uncomfortable working with electrical components or plumbing, it’s best to err on the side of caution and call a professional.
