Re: error code E33 on a zanussi FJS1225W washine machine
E33 is a water lever switch issue but it’s not specific as many aren’t.
Engineer time this one to be honest, try repairs@ and the directories for one.
You also won’t get a manual anywhere I’m afraid, they are not available to many engineers let alone the public, and those that may have one are unable to distribute due to copyright infringement.
