There are several possible reasons why your dishwasher might stop working after a few minutes:
Power issues: Check if there is a problem with the power supply to the dishwasher. Ensure that it is properly plugged in and that the power outlet is working. Sometimes, a tripped circuit breaker or a blown fuse can also cause the dishwasher to stop functioning.
Door latch problem: Many dishwashers have a safety feature that prevents them from running if the door is not securely latched. If the door is not closing properly or the door latch is faulty, the dishwasher may stop shortly after starting.
Water supply issues: If there is a problem with the water supply, such as a clogged water inlet valve or a kinked water supply line, the dishwasher may stop working. It needs a continuous flow of water to operate correctly.
Drainage problems: If the dishwasher is not able to drain the water properly, it might stop working to avoid flooding. Check for clogs in the drain hose or filter that could be preventing proper drainage.
Overheating: Some dishwashers have built-in thermal sensors that monitor the temperature inside the dishwasher. If the dishwasher overheats due to a malfunctioning heating element or some other issue, it may shut down as a safety measure.
Control board malfunction: The control board is like the brain of the dishwasher, and if it malfunctions, it can cause the dishwasher to stop working unexpectedly.
Motor or pump issues: Problems with the motor or pump that circulate water in the dishwasher can lead to a halt in the cleaning cycle.
Faulty sensors: Modern dishwashers have sensors that detect issues like water leakage or excess foam. If these sensors are faulty or detecting false positives, they may cause the dishwasher to stop working.
If you are unable to identify the issue and resolve it on your own, it's best to contact a professional appliance repair technician to diagnose and fix the problem. Dishwashers can be complex appliances, and attempting to repair them without proper knowledge and tools can lead to further damage.
