Dishwasher not draining — Rotterdam, Zuid-Holland

A dishwasher that leaves standing water at the bottom after every cycle is failing to drain properly, leaving dishes dirty and creating a breeding ground for odor-causing bacteria. The blockage usually sits in the drain pump, filter screen, or drain hose rather than in the household plumbing. An appliance-repair technician removes and cleans the filter assembly, checks the drain pump impeller for debris, inspects the hose and check valve for kinks or clogs, and runs a test cycle to confirm full drainage.
