Current machine: two connections - a red thin pipe and a grey tube. Red pipe screws on to a water pipe. Grey tube just sort of flops into an upright white plastic u-pipe.
New machine: same two connections (I believe) - the delivery men had been paid for installation but took one look at the white pipe and freaked out. Tried to trace it through the wall but there’s kitchen cupboards on the other side so couldn’t, and said they’d never seen anything like it so didn’t want to install the new machine.
