The following website:
shows a picture and makes this comment (back in 2002 -- the design may
have changed since):
"Again in my experience the Gaggia boilers tend to corrode internally.
They are attached to a brass group, and the combination of dissimilar
metals and hot electrically conductive water simply eats the aluminium.
This can also happen with aluminium thermoblocks, which is why some of
the more upmarket ones are now lined with stainless steel."
Is there any way to remediate a corroded boiler (assuming no replacement
is available) such as an immersion bath or other form of plating that is
food-safe as a vessel for boiling potable water as also able to
withstand the high temperatures of the heating element?
