Why is my dishwasher filling up with water from the sink?

Your dishwasher may be filling up with water from the sink due to a clog or blockage in the drain hose or the sink's Plumbing system. This can cause water to back up and flow into the dishwasher. It is important to check and clear any obstructions in the drain hose or the sink's plumbing to prevent this issue from happening.
