Door lock does not lock but makes a whirring noise like a motor and latch moves up and down – if you start m/wave the door will jump open. Error code E723 appears in display – any ideas guys. Thanks Franz Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
