My grandparents had a dishwasher from the 1980s. The contractor they hired to fix it didn’t even know how to take it out of the spot as it had an old design that attached it at the top.

ChatGPT both told me exactly why from the model number (had to disconnect a part), found a new part, and told me step by step how that part would be taken out.

We didn’t end up buying the new part, but it beat the repairman.
