The state of a Kenmore appliance failing to evacuate water following a wash cycle is a common household issue. This malfunction prevents the subsequent drying phase and renders the appliance unusable until resolved. A standing pool of water at the cycle’s conclusion is the primary symptom, often accompanied by a musty odor.
Addressing this problem promptly is essential for several reasons. Unresolved standing water can foster bacterial growth, creating unsanitary conditions. Furthermore, the accumulation of stagnant water can lead to mineral deposits and corrosion, potentially causing long-term damage to the appliance and shortening its lifespan. Historically, troubleshooting such issues required professional repair services, but many causes are readily addressed with basic knowledge and tools.
The following sections will detail the typical causes of this malfunction, including clogs in the drain system, issues with the drain pump, and problems with the appliance’s control components. Practical steps for diagnosis and resolution will also be presented, empowering owners to address the issue effectively.
1. Drain Hose Obstruction
Drain hose obstruction represents a primary cause of water retention within a Kenmore dishwasher following a cleaning cycle. The hose, responsible for directing wastewater from the appliance to the household plumbing, is susceptible to blockage. Identifying and resolving obstructions in this component is often the initial step in addressing a non-draining dishwasher.
-
Kinks and Bends
Sharp bends or kinks in the drain hose impede water flow. These restrictions create back pressure, overwhelming the drain pump’s capacity. Inspecting the hose’s entire length, ensuring smooth, unrestricted curves, is critical. A tightly bent hose behind the dishwasher, for instance, can severely restrict drainage, even if no other obstructions are present.
-
Food Particle Accumulation
Over time, food particles and debris can accumulate inside the drain hose, narrowing its internal diameter. This gradual buildup creates a significant impediment to water flow. Disconnecting the hose and flushing it with high-pressure water can dislodge accumulated debris. Ignoring this can lead to a complete blockage that requires hose replacement.
-
Grease Buildup
Grease introduced into the dishwasher through soiled dishes solidifies within the drain hose, particularly in cooler sections. This grease forms a sticky residue that traps other debris, exacerbating the blockage. Regular use of dishwasher cleaning agents that dissolve grease can prevent this accumulation. Otherwise, manual cleaning or hose replacement is necessary.
-
Connection Point Obstructions
Obstructions can occur at the connection points of the drain hose, both at the dishwasher itself and where it connects to the garbage disposal or drainpipe. These points are vulnerable to debris accumulation. Disconnecting and inspecting these connections for obstructions are important. A clogged connection can impede water flow even if the hose itself is clear.
Addressing these potential obstructions within the drain hose is often the first and simplest step in resolving water retention issues in a Kenmore dishwasher. A clear, unobstructed drain hose is essential for the proper functioning of the appliance, ensuring complete and efficient water evacuation after each cycle.
2. Drain Pump Failure
Drain pump failure directly correlates with a Kenmore dishwasher’s inability to drain water. The drain pump is the component responsible for actively expelling water from the dishwasher tub at the conclusion of a wash cycle. When this pump malfunctions, the water remains inside the appliance, resulting in the “not draining” condition. The pump’s failure can stem from various causes, ranging from electrical issues to physical obstructions within the pump housing. A non-functional pump renders the dishwasher inoperable, as the subsequent drying cycle cannot commence without water evacuation. A common example is a pump impeller jammed by a piece of broken glass, preventing the motor from turning and halting the draining process.
Understanding the connection between drain pump failure and the broader issue allows for targeted troubleshooting. For instance, if the dishwasher is emitting a humming sound during the drain cycle but no water is being expelled, this often indicates that the pump motor is receiving power but is unable to turn, suggesting an obstruction or internal component failure. Similarly, if the pump motor is completely silent, the issue may lie with the electrical supply to the pump or a burned-out motor. Diagnosing the precise cause, whether it be electrical or mechanical, is crucial for determining the appropriate repair strategy, ranging from clearing an obstruction to replacing the entire pump assembly.
In summary, drain pump failure is a critical factor in the occurrence of water retention within a Kenmore dishwasher. Identifying and addressing this malfunction is paramount for restoring the appliance’s proper operation. Recognizing the symptoms of pump failure and understanding potential causes enable effective troubleshooting, minimizing downtime and preventing further damage to the appliance. The integration of this knowledge into a broader diagnostic approach ensures a comprehensive assessment of the reasons behind a Kenmore dishwasher’s failure to drain effectively.
3. Filter system blockage
Filter system blockage is a significant factor contributing to a Kenmore dishwasher’s inability to drain. The filter system, typically located at the bottom of the dishwasher tub, is designed to trap food particles and debris, preventing them from entering the drain pump and potentially causing damage or obstructions in the drain line. When this filter becomes clogged with excessive debris, it restricts the flow of water, effectively preventing the dishwasher from draining properly. The accumulation of food scraps, seeds, and other materials reduces the filter’s efficiency, leading to a backup of water in the dishwasher tub after the wash cycle concludes. For instance, neglecting regular cleaning of the filter after preparing meals with leafy vegetables or starchy foods can quickly lead to a significant blockage and subsequent drainage issues.
The proper maintenance of the filter system is, therefore, crucial for ensuring the efficient operation of the dishwasher’s drainage mechanism. A blocked filter not only impedes water flow but can also put undue strain on the drain pump, potentially leading to premature pump failure. Regular cleaning of the filter, typically involving its removal, rinsing under running water, and the removal of any accumulated debris, is essential preventive maintenance. Some Kenmore dishwashers have multiple filters, requiring all to be cleaned for optimal function. Furthermore, understanding the dishwasher’s user manual will clarify the specific cleaning procedure and recommended frequency for maintaining the filter system’s integrity.
In conclusion, filter system blockage directly impacts the draining capability of a Kenmore dishwasher. Consistent maintenance, including the removal and cleaning of the filter, represents a proactive approach to preventing drainage problems. Addressing this aspect of dishwasher maintenance ensures efficient water evacuation, prevents potential damage to the drain pump, and contributes to the appliance’s overall longevity. Addressing the filter should be one of the first troubleshooting steps when confronted with a Kenmore dishwasher that fails to drain.
4. Air gap malfunction
An air gap malfunction presents a potential impediment to the proper draining of a Kenmore dishwasher. The air gap is a plumbing component designed to prevent backflow of contaminated water from the sink drain into the dishwasher. Its primary function is to maintain a physical separation between the dishwasher drain hose and the household drain system, ensuring that wastewater cannot siphon back into the appliance. When the air gap becomes clogged or otherwise malfunctions, it can restrict airflow and impede the dishwasher’s ability to evacuate water effectively, leading to a “not draining” condition. For example, a buildup of grease and food particles within the air gap can obstruct the vent, creating negative pressure that prevents the dishwasher drain pump from operating at full capacity.
The significance of a properly functioning air gap lies in its dual role of preventing contamination and facilitating efficient drainage. A malfunctioning air gap may not only compromise the dishwasher’s draining capabilities but also increase the risk of introducing unsanitary water into the appliance, potentially contaminating dishes and utensils. Diagnosing an air gap malfunction typically involves inspecting the component for visible obstructions and ensuring that the vent is clear. In some cases, disassembly and cleaning of the air gap may be required to restore its functionality. For instance, a homeowner might find that removing accumulated debris from the air gap immediately resolves the drainage problem, highlighting the direct connection between the component’s condition and the dishwasher’s performance.
In summary, air gap malfunction is a relevant factor to consider when troubleshooting a Kenmore dishwasher that is not draining. Its impact extends beyond simple drainage issues, encompassing potential contamination concerns. Addressing a malfunctioning air gap, whether through cleaning or replacement, is essential for maintaining both the operational efficiency and the sanitary integrity of the dishwasher. This component warrants inspection and maintenance as part of a comprehensive approach to resolving drainage problems in Kenmore dishwashers.
5. Control board error
Control board malfunctions, though less frequent than mechanical issues, represent a potential cause for a Kenmore dishwasher’s failure to drain. The control board acts as the central processing unit of the appliance, governing the timing and execution of various functions, including the activation of the drain pump. When the control board malfunctions, it may fail to send the signal necessary to initiate the drain cycle, resulting in water retention within the dishwasher tub. Identifying control board errors requires a systematic approach, often involving diagnostic testing and, in some cases, professional intervention.
-
Relay Failure
The control board employs relays to switch electrical circuits, including the one powering the drain pump. A failed relay may prevent voltage from reaching the pump, irrespective of the control board’s programming. For example, a burnt-out relay coil or stuck contacts would inhibit the pump’s operation, even if the control board is otherwise functioning correctly. Testing the relay with a multimeter can confirm its operational status.
-
Software Corruption
Modern Kenmore dishwashers utilize software to manage cycle sequences and component activation. Software corruption or glitches can disrupt the proper execution of the drain cycle, preventing the control board from signaling the drain pump to activate. This might manifest as intermittent draining issues or a complete failure to drain. Resetting the control board or, in severe cases, reflashing the software, might resolve these issues.
-
Sensor Malfunction
The control board relies on sensor inputs to determine cycle progression and activate specific functions. If a sensor providing feedback on water level or cycle completion malfunctions, it may send incorrect data to the control board. This erroneous information could prevent the control board from initiating the drain cycle, assuming that the dishwasher is not ready to drain. Replacing the faulty sensor may restore normal operation.
-
Component Burnout
Over time, components on the control board can degrade or burn out due to electrical surges or general wear and tear. This damage can disrupt the control board’s ability to function correctly, potentially affecting the drain cycle.
