The heating element in a dishwasher serves a crucial function in the drying process. Its primary purpose is to heat the air and water inside the dishwasher to help dry the dishes after the cleaning cycle. When the dishwasher has finished washing, the heating element raises the temperature inside the dishwasher, which causes the water on the dishes and the dishwasher's interior to evaporate quickly, leaving the dishes dry and ready for use.
If the heating element is not working properly or malfunctions, several issues can arise:
Dishes remain wet: The most noticeable effect of a faulty heating element is that the dishes won't dry effectively. When the heating element fails to heat the air and water inside the dishwasher, the drying process becomes inefficient, leaving dishes wet or covered in water spots.
Extended cycle time: If the dishwasher relies on the heating element to advance through specific cycles, a malfunctioning element may cause the dishwasher to take longer to complete its cycle.
Reduced cleaning performance: In some dishwasher models, the heating element is also responsible for maintaining the water temperature during the wash cycle. If the element is not working correctly, the dishwasher may struggle to achieve the necessary temperature for effective cleaning, resulting in subpar cleaning performance.
Error codes or warning lights: Many modern dishwashers have built-in diagnostic systems that detect issues like a faulty heating element. In such cases, the dishwasher may display error codes or activate warning lights on the control panel.
Increased energy consumption: A malfunctioning heating element may draw excessive power or remain on continuously, leading to higher energy consumption and potentially higher utility bills.
If you suspect that your dishwasher's heating element is not working properly, it's essential to have it checked and repaired by a qualified technician. They can diagnose the issue, determine whether the heating element needs replacement or repair, and ensure that the dishwasher functions optimally, providing clean and dry dishes after each cycle.
