Breville BES870 Steam Problem
We have one of these machines and it has developed a periodic (every few weeks) problem with the steam.
Periodically, when we go to steam the milk, we find that steam is also coming out of the grouphead aperture, at about roughly the same pressure as it is coming out of the wand.
We have cleaned the machine thoroughly, but it has kept occurring. It does not seem to make any difference if we have the grouphead handle and basket in or not.
Has anyone else encountered this problem before? If so, is there a fix we can apply? Many thanks!
