Yes, it is normal to have some water in the bottom of the dishwasher after a cycle. The water at the bottom of the dishwasher is typically there to perform specific functions during the washing process. Here's why you might find water in the dishwasher after a cycle:
Filtering and draining: Dishwashers are designed to filter out food particles and debris during the wash cycle. The water at the bottom acts as a reservoir to collect these particles, preventing them from recontaminating the dishes. After the wash cycle is complete, the dishwasher's drain pump expels this water, along with the collected debris, during the draining phase.
Heating element protection: In some dishwashers, a small amount of water remains at the bottom to protect the heating element. Leaving a little water helps prevent the heating element from burning out or getting damaged due to direct contact with the dishwasher's base.
Sealing and avoiding air gaps: Water at the bottom can create a seal that prevents air from entering the dishwasher during the wash cycle. This seal is essential for proper functioning and to avoid potential leaks.
While it is normal to have some water at the bottom of the dishwasher, excessive water or standing water that does not drain properly may indicate an issue with the dishwasher. If you notice an unusually large amount of water or persistent standing water in the dishwasher after a cycle, it could be due to a clog or malfunction in the drainage system, filters, or pump. In such cases, it is advisable to check the dishwasher's components or seek professional assistance to resolve the problem and ensure proper drainage.
