My dishwasher seems to be steaming a lot at end of cycle..

Earl, unfortunately this is normal operation. Especially when using the heat dry option. We get a lot of questions around the holidays when they are being used much more frequently, and multiple times in one day. You tend to notice things that you might not have before. But try and advise the grandchildren to avoid that since it’s hot, or maybe opt to run it at a different time if possible. Hope this helps!
