Quick Answer
If your dishwasher door won’t latch, the most common causes are a worn door latch, misaligned hinges, damaged strike plate, faulty door switch, or obstruction around the door seal. A dishwasher will not start unless the door closes and locks properly.
A dishwasher that refuses to close properly can stop the appliance from operating altogether. In many models, the control system will not allow a wash cycle to begin until the door latch engages completely.
Fortunately, many dishwasher door not closing problems can be diagnosed quickly and repaired without replacing the entire appliance.
