I just use plain citric acid mixed with water and let it set for about
45 minutes. Then I drain it and rinse it several times like seven or
eight full boilers maybe even more. It seems to do a really good job
with my water quality. I did the machine I have now at 5 years when
one of the boiler elements went out.
Yup - exactly that. Acid deals with the salts deposited from the water,
plus removes the blackened copper residues nicely. Citric is used in
food, citric is actually present in coffee... But you do need to clean
it out. I tend to just put hot water in, and spoon in the citric. Like
Herman: I'm usually paranoid about washing it out. It'll loosen flakes
of black crud too - and you DON'T want that floating about in the
machine. The little jet at the top of the e61 is 0.6mm (from memory).
I think (but do NOT know for certain..) the white stuff in the element
is just Magnesium Dioxide. You probably want to remove all that too and
flushing plus the citric rinse will achieve it.
Like I said: I don't know any neat and tidy approach to this problem.
Water everywhere... I don't have any saucepan shaped dents in my head
so the mess was clearly confined to the kitchen sink area :)
