Yesterday I decalcified my Moccamaster, also gave it a cleaning cycle to remove the coffee oils and I took the WMF coffee grinder apart to give it a thorough cleaning too. This morning I enjoyed the result. A damn fine cup of Libertad coffee :) #Mehpost
Moccamaster says it is sufficient to decalcify after 100 runs, but the very hard water here in Munich calls for a monthly cycle. And never use citric acid for that! The heating element in a Moccamaster is pure copper, so it calls for (UPDATE) lactic acid instead, according to Technivorm. And as I plan to keep this machine working for many, many years, I will follow their guidelines slavishly ;)
@jwildeboer Lactic acid is better. I don't know exactly why, but I buy the original decalcifyier (lactic acid - based) from DeLonghi® for our Dedica® machine.
And using Brita® filtered water for brewing.

@jwildeboer the electronic of our Dedica machine offers many sophisticated options for settings and special modes by using special "sequences" of the three buttons & LED panel.

I can use among other things three settings for water hardness, which will trigger (after e.g. 100, 200, 300) an half automatic decalcifying mode.
The right button will blinking with orange backlight, if U confirm w/ special button pushing, and fill in the decalcifying solution, a special pump-pulsating rhythm starts.
