eli5: dishwasher tablet dispensing

227 views

how does this work? I put a little tablet in the dishwasher tablet section and close the little covering. Does this then open at some time during the wash? at what time? does the tablet then just randomly float around the interior?

When a cycle starts, the first thing a dishwasher will do is fill the tub with hot water and aggressively spray to get everything hot and soaked so most of the food particles will fall off. Then the pump kicks on and pumps that water out. The next cycle will do the same but this time it will signal the dispenser to open and expose the detergent. This is where the “clean” happens. The third cycle will be a brief rinse. Older dishwashers may have had a dry cycle where a heating element evaporates the water on the dishes to get them mostly dry. Now with energy saving appliances, that last cycle is a half-ass drying that only relies on the heat from the last cycle to evaporate *some* water.
