is it dangerous yes or no? housemate did a wash that finished at 11am and i’ve just discovered the machine ( 12 hours later ) has been turned on and not emptied all day. is this a hazard or no as i know sometimes leaving the machine on for ages can cause it to start smoking. Just asking as they always leave hob on etc and do this often and i’m hoping this isn’t another safety hazard i have to start worrying about or am i just being paranoid?
