Well I do not agree entirely, depending how bad the plastic was melted and what KIND of plastic it was originally, you could definitely have some toxin. But I do agree on running the load again...
This detailed answer was placed on the discussion page by user "Chris Plastic" (see link to profile on discussion page):
A plastic item placed in a dish-washer would normally be intended for food contact use. If the material was a thermoplastic (e.g., polypropylene), reheating to viscous fluid and then cooling to solid does not usually result in significant breakdown. Such plastics can usually be dishwashed without problem. Thermoset materials are often regarded as plastics (e.g., Melamine). They would tend to eventually breakdown into smaller particles, ultimately into powder, rather than remelting. They can have good dishwasher stability.That food-contact plastic would be normally approved by the US FDA (Food and Drug Administration) possibly for repeat use. They would screen plastics for the impact of chemicals which could migrate out of them. I doubt if dishwashing tests are specifically conducted, but sensitive tests are conducted to determine the nature of these migrating chemicals and their concentration. The likely toxicity would then be assessed. These tests would dictate whether or not FDA approval is granted.Harmful toxins are unlikely to be released. Anything migrating from the plastic would be expected to be flushed away along with the grease, etc., washed from the other items.Materials like polymethylmethacrylate (acrylic, e.g., Plexiglas) and polycarbonate (e.g., Lexan) can both crack and craze especially if items are packed tightly in a dishwasher. However, this is not linked to your comments about toxicity.
plastic plants are not harmful to your goldfish aquarium.
Yes
Yess it is pefectly fine too
Probably. It will depend both on the plastic the bottle is made from and its intended purpose.
Not Microwavable: No para microondas Not Dishwasher Safe: No apto para lavavajillas/lavaplatos
It is harmful chemicals and physical effects
If you can smell burnt plastic then you could potentially be in danger. Smoke from burning plastic can be harmful to breathe.

No. Many vital parts in the dishwasher are plastic. Usually, the drain hose is plastic, too. Drain cleaners are ok for PVC pipes, but too caustic for other types of plastic. Drain cleaners also cause corrosion of metal parts.
No
Dioxin poisoning. Cancer from plastic fibers.
My wife always uses the dishwasher to sterilize the bottles. However, the bottles we use for our baby are dishwasher safe. If your bottles are not dishwasher safe, you may want to wash them with warm water and soap.
