If your dishwasher is draining and working fine until the final rinse water doesn’t drain, don’t worry. All is normal. Economy Dishwashers especially countertop dishwashers use residual heating. During the final rinse, the water is heated up extra hot to ensure clean and spot free dishes. Instead of draining this super hot water, it will save it in the bottom of the dishwasher to dry dishes. At this time, the dishwasher is in pause mode. After several minutes when the water temperature drops, it is no longer needed to dry dishes. The water is drained and cycle is complete.
