Why is there water in the bottom of the dishwasher when it is not in use?

Water in the bottom of the dishwasher when it's not in use can be due to a few reasons. One common reason is a faulty water inlet valve that is not closing properly, allowing water to leak into the dishwasher. Another reason could be a clogged or malfunctioning drain hose, preventing water from properly draining out. It's important to address these issues promptly to prevent damage to the dishwasher and potential water leakage.
