Dishwashers are a key appliance in modern kitchens, providing convenience and time-saving benefits for homeowners. However, like all appliances, they can encounter problems from time to time. One of the most frustrating issues that can arise with your Kenmore Dishwasher Model 665.16761691 is a failure to drain properly. This can lead to standing water in the bottom of the dishwasher, leaving dishes dirty and wet. Fortunately, several potential causes exist for this issue, and with the right knowledge and tools, you can troubleshoot and resolve it on your own.
Common Reasons Why Your Kenmore Dishwasher Won’t Drain
Before diving into the troubleshooting steps, it’s important to understand why your dishwasher may not be draining. Several factors can lead to drainage issues, including:
- Clogged Drain Hose: One of the most common reasons for drainage issues is a clogged or blocked drain hose. This hose connects the dishwasher to your home’s plumbing system, and if it becomes obstructed, water cannot properly exit the machine.
- Faulty Drain Pump: The drain pump is responsible for pumping water out of the dishwasher. If it’s malfunctioning or broken, the dishwasher won’t drain.
- Clogged Filter or Garbage Disposal: A clogged filter or garbage disposal can also prevent the dishwasher from draining properly. These components are crucial in trapping food particles and debris, and a buildup can block the drainage system.
- Faulty Check Valve: The check valve prevents water from flowing back into the dishwasher after it has drained. If this valve becomes damaged or stuck, water may not drain properly.
- Timer or Control Board Issue: The timer or control board directs the dishwasher’s operations, including when to drain. If there’s a problem with the control board or timer, it may not be triggering the drain cycle properly.
- Kinked or Bent Drain Hose: Sometimes, the drain hose can become kinked or bent, restricting the flow of water out of the machine. This could be due to improper installation or accidental damage.
Now that we know the potential causes, let’s explore the steps you can take to troubleshoot and fix your Kenmore Dishwasher Model 665.16761691.
Step 1: Check the Drain Hose
The first thing you should check is the drain hose. If the hose is clogged or kinked, water cannot flow freely from the dishwasher.
How to Check and Fix:
- Locate the Drain Hose: The drain hose is typically connected at the bottom of the dishwasher and leads to the garbage disposal or drain line. You may need to remove the dishwasher’s lower rack to access it.
- Inspect the Hose for Clogs or Kinks: Look for any visible obstructions or bends in the hose. If you find any, straighten out the hose or remove the blockage.
- Clean the Hose: If the hose appears clear but you still notice drainage issues, you can detach the hose and flush it with water. Use a long, flexible brush to remove any buildup that could be clogging it.
- Reattach the Hose: Once cleaned, reattach the hose securely to ensure it’s properly positioned and not obstructed.
Step 2: Examine the Drain Pump
The drain pump is responsible for expelling water from the dishwasher. If it’s malfunctioning or clogged, the dishwasher won’t drain properly.
How to Check and Fix:
- Access the Drain Pump: The drain pump is usually located at the bottom of the dishwasher. Depending on the model, you may need to remove the lower spray arm, filter, or other parts to access it.
- Inspect the Pump for Obstructions: Check for any debris or food particles that may have gotten stuck in the pump. Clean the area thoroughly.
- Listen for Unusual Noises: If you hear a buzzing or humming sound when the dishwasher should be draining, it could indicate that the pump is trying to work but is unable to because of a malfunction. In this case, the pump may need to be replaced.
Step 3: Clean the Filter
Your dishwasher likely has a filter designed to catch food particles and debris. If this filter becomes clogged, it can prevent the dishwasher from draining properly.
How to Clean the Filter:
- Locate the Filter: The filter is usually located at the bottom of the dishwasher, beneath the spray arm or at the base of the tub.
- Remove the Filter: Most Kenmore dishwashers have removable filters. Take it out gently, being careful not to damage it.
- Clean the Filter: Rinse the filter under warm water to remove food particles and debris. If it’s very clogged, use a soft brush to scrub it clean.
- Reinstall the Filter: After cleaning, put the filter back in place, ensuring it’s securely installed.
Step 4: Inspect the Garbage Disposal
A clogged garbage disposal can affect the dishwasher’s drainage. The dishwasher drain hose is often connected to the garbage disposal, and a blockage in the disposal can prevent water from draining.
How to Check and Fix:
- Check for Blockages: Run the garbage disposal and check for any blockages or clogs. If the disposal is clogged, it may be preventing water from draining properly from the dishwasher.
- Clear the Disposal: If you find any debris in the disposal, clear it out. You can use a plunger or a wrench to break up tough blockages. Once clear, run the disposal with water to ensure it’s draining properly.
Step 5: Examine the Check Valve
The check valve ensures that water doesn’t flow back into the dishwasher after it has been drained. If the valve is stuck or malfunctioning, it may prevent the water from draining properly.
How to Check and Fix:
- Locate the Check Valve: The check valve is typically located near the pump or the drain hose connection.
- Inspect for Damage: Check if the check valve is stuck or damaged. If it is, it may need to be replaced.
- Test the Valve: Try to move the valve gently to see if it’s stuck. If it moves freely, it’s working properly. If it’s stuck or broken, it will need to be replaced.
Step 6: Test the Timer or Control Board
The timer or control board regulates the dishwasher’s cycle, including when to drain. If either of these components is malfunctioning, the dishwasher may not drain properly.
How to Check and Fix:
- Check for Error Codes: Some dishwashers display error codes if there’s a problem with the control board or timer. Refer to your user manual for specific error codes related to drainage issues.
- Test the Timer or Control Board: If no error codes are present, but the dishwasher still isn’t draining, you may need to test the timer or control board. This typically requires specialized tools like a multimeter.
- Replace the Timer or Control Board: If you find that the timer or control board is faulty, it will need to be replaced. You can order a replacement part and install it yourself or hire a professional to do so.
Step 7: Professional Help
If you’ve gone through all the troubleshooting steps above and your dishwasher still won’t drain, it may be time to call in a professional. A certified repair technician can diagnose the issue more accurately and fix it in a timely manner.
