Why is there water at the bottom of my dishwasher?

Water at the bottom of your dishwasher is normal as it is used to clean dishes. However, if there is excess water or it is not draining properly, it could be due to a clog in the drain hose or pump, a faulty float switch, or a malfunctioning drain valve. It is important to troubleshoot and fix the issue to prevent damage to your dishwasher.
