The most common reason a dishwasher breaks is due to problems with its components or mechanical parts. Some of the common reasons include:
Faulty Door Latch: The door latch is responsible for keeping the dishwasher door securely closed during operation. If it malfunctions, the dishwasher may not start or continue its cycle.
Drainage Issues: Clogs or blockages in the dishwasher's drainage system can lead to standing water at the bottom of the unit or incomplete draining after a cycle.
Water Inlet Valve Problems: The water inlet valve controls the flow of water into the dishwasher. If it fails to open or close properly, the dishwasher may not fill with water or might leak.
Pump Failure: The dishwasher's pump is responsible for circulating water during the wash and drain cycles. If the pump motor or impeller is faulty, it can result in poor cleaning or draining.
Heating Element Issues: The heating element heats the water during the wash cycle and helps with drying. If the element malfunctions, it can lead to poor cleaning and wet dishes at the end of the cycle.
Spray Arm Blockages: Clogs in the spray arms can prevent water from reaching all areas of the dishwasher, resulting in inadequate cleaning.
Control Board Malfunctions: Problems with the dishwasher's control board can lead to issues with cycle selection, timing, or error codes.
Sensor Problems: Modern dishwashers often have sensors that detect water level, temperature, or soil levels. If these sensors fail, it can impact the dishwasher's performance.
Leaking Seals and Gaskets: Worn-out or damaged door seals and gaskets can cause leaks during the wash cycle.
Overuse or Age: Frequent heavy usage or older age can contribute to the general wear and tear of the dishwasher's components, leading to various malfunctions.
Regular maintenance, proper loading techniques, and promptly addressing any minor issues can help prolong the life of a dishwasher and reduce the likelihood of breakdowns. If your dishwasher experiences problems, it's best to consult a professional appliance repair technician to diagnose and fix the issue properly.
