Base and base plate
The base of the machine, if you let water stagnate in the drip tray, can
result in the formation of rust. The phenomenon affects both machine with
chrome base that painted, although the latter phenomenon is more frequent and
occurs even in the absence of particular neglect. If the rust is very deep can
puncture the metal.
The phenomenon of rust can also affect the sub base. Is mainly due to
condensation that can form under the base and is accentuated if the machine is
kept unused in humid environments.
In the case of a painted may also depend on the formation of rust in the
drip tray.
