Common Kenmore 665 Dishwasher Issues and Diagnosis
Before diving into specific solutions, let's outline the most frequent problems users face with the Kenmore 665 series and how to approach their diagnosis. Effective Kenmore dishwasher troubleshooting begins with accurate identification of the symptom.
Dishwasher Not Starting
This is a common, albeit frustrating, symptom. If your Kenmore 665 dishwasher refuses to start, several factors could be at play. First, ensure the unit is receiving power; check if the circuit breaker has tripped or if the power cord is securely plugged into a working outlet. Verify that the dishwasher door is completely latched, as most models have a safety interlock that prevents operation if the door isn't fully closed. Check the control panel for any error codes displayed, which can provide specific clues. If none of these simple checks reveal the cause, the issue might stem from the door latch switch, the electronic control board, or the start switch itself.
Water Not Draining
A dishwasher that leaves standing water after a cycle is a clear sign of a drainage problem. The most common culprit is a clogged drain filter, usually located at the bottom of the tub. Remove and clean this filter regularly as part of your maintenance routine. Another frequent cause is a kinked or clogged drain hose that connects the dishwasher to your sink's plumbing or garbage disposal. Inspect the entire length of the hose for any obstructions or sharp bends. If you have a garbage disposal, ensure the knockout plug was removed when the dishwasher was installed, as this prevents water from entering the disposal and subsequently draining. A malfunctioning drain pump or a clogged sump area within the dishwasher can also impede drainage.
Dishwasher Leaking Water
Leaks can occur from various points. Start by checking the door seal or gasket for any damage, debris, or wear. A torn or dirty gasket can allow water to escape during the wash cycle. Inspect the water inlet valve, typically located at the base of the dishwasher, for cracks or loose connections. Ensure the dishwasher is level; an unlevel unit can cause water to pool and leak from the door. Check the spray arms for cracks, as damaged arms can spray water directly at the door seal, overwhelming it. Finally, examine the fill and drain hoses, as well as connections to the pump and tub, for any signs of leaks or damage.
Dishes Not Getting Clean
If your dishes aren't coming out spotless, the problem might be with water circulation or detergent dispensing. Ensure the spray arms are not blocked by large dishes and can rotate freely. Check the spray arm nozzles for clogs; you can often clear these with a toothpick or a small wire. Verify that you are using the correct type and amount of detergent. Older or improperly stored detergent can lose its effectiveness. Make sure the water temperature is adequate, as most dishwashers require water heated to at least 120°F (49°C) for optimal cleaning. Clogged filters or a faulty water inlet valve can also restrict water flow, impacting cleaning performance.
The most effective way to diagnose a Kenmore 665 dishwasher issue is to observe precisely when and where the problem occurs.
Step-by-Step Solutions for Common Problems
Once you've identified the symptom, it's time to implement targeted solutions. These steps are designed for straightforward fixes applicable to many Kenmore dishwasher model 665 troubleshooting scenarios.
Fixing a Dishwasher That Won't Start
- Power Check: Ensure the dishwasher is plugged in. Verify the home's circuit breaker for the dishwasher has not tripped; reset it if necessary. Test the outlet with another small appliance to confirm it's live.
- Door Latch: Open the dishwasher door, inspect the latch mechanism for debris or damage, and ensure it clicks securely when closed. Listen for the 'click' that signifies the door is latched.
- Control Lock: Some Kenmore models have a control lock feature. Check your Kenmore 665 dishwasher manual to see if this is enabled and how to disable it (often by pressing and holding a specific button for several seconds).
- Door Switch: If the above steps don't resolve the issue, the door switch might be faulty. This often requires removing the kick panel at the bottom front of the dishwasher to access and test the switch with a multimeter, or replacing it if necessary.
Clearing Drainage Obstructions
- Clean the Filter: Locate and remove the filter assembly at the bottom of the dishwasher tub. Rinse it thoroughly under running water, removing food particles and debris. Reinsert it securely.
- Inspect the Drain Hose: Disconnect the drain hose from the sink plumbing or disposal (place a towel to catch residual water). Check the hose for kinks and inside for blockages. A plumber's snake or stiff wire can help dislodge stubborn clogs. Ensure the hose is properly reconnected.
- Garbage Disposal Check: If connected to a garbage disposal, confirm the knockout plug was removed during installation. If it's a new installation, run the disposal briefly to clear any debris that might be blocking the dishwasher's drain path.
Addressing Dishwasher Leaks
- Inspect Door Gasket: Clean the door gasket with warm, soapy water and a soft cloth. Check for tears or deformation. Small tears might be temporarily sealed with silicone sealant, but replacement is recommended for significant damage.
- Check Water Inlet Valve: With the dishwasher disconnected from power, examine the water inlet valve for leaks. If it's cracked or leaking, it needs replacement. Ensure the connection hose is tight.
- Level the Dishwasher: Use a spirit level to check if the dishwasher is level from front to back and side to side. Adjust the leveling feet at the base of the unit to correct any tilt.
Improving Dishwashing Performance
- Clear Spray Arms: Remove the spray arms (consult your Kenmore 665 dishwasher manual if unsure). Use a toothpick or needle to clear any debris from the spray holes. Ensure they spin freely when reinstalled.
- Detergent and Rinse Aid: Use a high-quality dishwasher detergent and ensure it's fresh. Use rinse aid to help water sheet off dishes, preventing spots and improving drying.
- Water Temperature: Run hot water at the kitchen sink before starting the dishwasher to ensure the water entering the machine is sufficiently hot. If your home's water heater is set too low, adjust it to at least 120°F (49°C).
To prevent future clogs, scrape large food particles off dishes before loading, and run the hot water at your kitchen sink before starting the dishwasher to ensure it fills with hot water immediately.
Advanced Troubleshooting and Maintenance
When basic fixes don't resolve your Kenmore dishwasher model 665 issues, it's time to consider more advanced diagnostics and proactive maintenance. These steps often require a bit more technical confidence but can still be managed by a motivated homeowner.
Understanding Error Codes
Many modern Kenmore dishwashers, including the 665 series, use error codes to signal specific problems. These codes are your most direct clue to what's happening internally. Common codes might indicate issues with water fill (e.g., not sensing water), drain problems, or heating element malfunctions. Always refer to your Kenmore dishwasher manual for a comprehensive list of error codes specific to your model and their associated meanings and recommended troubleshooting steps. For instance, an error code related to draining might prompt a deeper inspection of the pump impeller or air gap.
Checking the Water Inlet Valve
If your dishwasher isn't filling with water or is leaking from the base, the water inlet valve is a prime suspect. This valve controls the flow of water into the dishwasher. It's usually located at the back or bottom of the unit where the water supply line connects. You can test its function using a multimeter to check for continuity. If it appears faulty or is visibly damaged, replacement is straightforward, typically involving disconnecting the water line and unscrewing the old valve to install a new one. Ensure the water supply is turned off and the unit is disconnected from power before attempting this.
The Drain Pump and Motor
Issues with draining can sometimes point to the drain pump itself or, less commonly, the main circulation motor if it has an integrated pump. The drain pump is responsible for expelling water at the end of cycles. If you hear the motor humming but water isn't draining, the pump might be clogged with debris (like glass shards or hard plastic). You may need to remove the pump assembly to clear it. If the pump is silent or making unusual noises, it might be failing and require replacement. Accessing these components usually involves removing the lower access panels of the dishwasher.
Regular maintenance is the most effective form of advanced troubleshooting, preventing many issues before they start.
A well-maintained dishwasher is a reliable dishwasher.
Routine Maintenance for Longevity
Beyond the filter cleaning, several other maintenance tasks will keep your Kenmore dishwasher 665 running smoothly. Periodically run an empty cycle with a dishwasher cleaner product or a cup of white vinegar placed on the bottom rack to descale the interior, clean the tub, and remove odors. Check the dishwasher's leveling regularly, as an uneven unit can affect performance and cause leaks. Ensure the door hinges are clean and lubricated, and that the door opens and closes without resistance. If you have hard water, consider using a water softener or regularly adding a dishwasher cleaner designed to combat mineral buildup.
Always disconnect power to the dishwasher and turn off the water supply before attempting any internal repairs or component replacements.
