It's also difficult for someone who isn't familiar with it to use it as
an extra button has to be pressed just before closing it to (finally)
say "do what I've set up on the switches".

Mine you just close it again. No need to hit a "carry on" button. To check
the display, simply open it a crack and close it. It is also good for
sticking an extra bit of cutlery in if the programme has already started.
The pump stops when the door is open and starts again when closed. There is
no start button.
