What is the most common problem with GE dishwashers?

What is the most common problem with GE dishwashers is not draining and leaving standing water at bottom of tub, accounting for about 30 percent of service calls. For GE models like GDT630PYRFS, GDP630PYRFS, and PDT775SYNFS, top failure is drain pump clogged with food particles, glass shards, and grease or failed drain pump motor at 30 to 60 dollars that causes water to remain at bottom after cycle and dishwasher not completing cycle, fix by cleaning filter under lower rack monthly by removing lower rack, twisting filter, and rinsing under hot water to remove food, and checking air gap on countertop or garbage disposal connection under sink for clog where drain hose connects, as clog there prevents draining. Second most common is not cleaning dishes well and leaving food residue due to spray arm holes clogged with food that blocks water jets, or filter clogged, or low water temperature below 120 degrees that prevents detergent dissolving. Third is not filling with water due to inlet valve clogged with sediment from hard water at 15 to 30 dollars or float switch stuck in up position inside tub. Fourth is leaking water onto floor due to door gasket worn after 5 to 8 years. Fifth is not drying dishes due to heating element failed at 30 to 60 dollars or rinse aid dispenser empty. Regular maintenance like cleaning filter monthly and using rinse aid reduces most common problems.
