As the GGP said, the menu can be exited without updating by scrolling down. The interface isn't intuitive, but it's not a hard block.
An appliance going "nope, I have one path for this" is, tbh, to be expected. A dishwasher washes dishes, and the idea that there is a secret-sauce way to tell it to do something it isn't actively presenting to you is not something a reasonable person is going to expect. It's why my dishwasher has like eight buttons on the top--it enumerates everything it can do. So if that appliance is hiding its verbs, then a reasonable person is going to assume it doesn't have any.
It would be best if most machines didn't talk to us, at all. Press a button: it runs. Nothing more.
